Merely quantitative differences, beyond a certain point, pass into qualitative changes.
Karl Marx
Not too long ago thousands spent their lives as recluses to find spiritual vision in the solitude of nature. Modern man need not become a hermit to achieve this goal, for it is neither ecstasy nor world-estranged mysticism his era demands, but a balance between quantitative and qualitative reality. Modern man, with his reduced capacity for intuitive perception, is unlikely to benefit from the contemplative life of a hermit in the wilderness. But what he can do is to give undivided attention, at times, to a natural phenomenon, observing it in detail, and recalling all the scientific facts about it he may remember. Gradually, however, he must silence his thoughts and, for moments at least, forget all his personal cares and desires, until nothing remains in his soul but awe for the miracle before him. Such efforts are like journeys beyond the boundaries of narrow self-love and, although the process of intuitive awakening is laborious and slow, its rewards are noticeable from the very first. If pursued through the course of years, something will begin to stir in the human soul, a sense of kinship with the forces of life consciousness which rule the world of plants and animals, and with the powers which determine the laws of matter. While analytical intellect may well be called the most precious fruit of the Modern Age, it must not be allowed to rule supreme in matters of cognition. If science is to bring happiness and real progress to the world, it needs the warmth of man's heart just as much as the cold inquisitiveness of his brain.
Franz Winkler
The quantitative degeneration of all things is closely linked to that of money, as is shown by the fact that nowadays the ‘worth’ of an object is ordinarily ‘estimated’ only in terms of its price, considered simply as a ‘figure’, a ‘sum’, or a numerical quantity of money; in fact, with most of our contemporaries, every judgment brought to bear on an object is nearly always based exclusively on what it costs. The word ‘estimate’ has been emphasized because it has in itself a double meaning, qualitative and quantitative; today the first meaning has been lost to sight, or what amounts to the same thing, means have been found to equate it to the second, and thus it comes about that not only is the ‘worth’ of an object ‘estimated’ according to its price, but the ‘worth’ of a man is ‘estimated’ according to his wealth.
René Guénon
We forget that, although each of the liberties which have been won must be defended with utmost vigour, the problem of freedom is not only a quantitative one, but a qualitative one; that we not only have to preserve and increase the traditional freedom, but that we have to gain a new kind of freedom, one which enables us to realize our own individual self; to have faith in this self and in life.
Erich Fromm (The Fear of Freedom)
There is a very real relationship, both quantitatively and qualitatively, between what you contribute and what you get out of this world.
Oscar Hammerstein II
The calculative exactness of practical life which the money economy has brought about corresponds to the ideal of natural science: to transform the world by mathematical formulas. Only money economy has filled the days of so many people with weighing, calculating, with numerical determinations, with a reduction of qualitative values to quantitative ones.
Georg Simmel (The Sociology of Georg Simmel)
Our goal is to create a beloved community and this will require a qualitative change in our souls as well as a quantitative change in our lives.
Martin Luther King Jr.
In business, qualitative measurements and quantitative measurements are equally important.
Hendrith Vanlon Smith Jr.
If you are going to use the results of market research to make a big business decision, then it’s a good idea to do quantitative research rather than qualitative.
Pooja Agnihotri (Market Research Like a Pro)
When we burn fossil fuel for energy we are, in qualitative terms, doing nothing more wrong than burning wood. Our wrongdoing, if that is an appropriate term, is taking energy from Gaia hundreds of times faster than it is naturally made available. We are sinning in a quantitative not a qualitative way.
James E. Lovelock (The Revenge of Gaia)
A Value Proposition creates value for a Customer Segment through a distinct mix of elements catering to that segment’s needs. Values may be quantitative (e.g. price, speed of service) or qualitative (e.g. design, customer experience).
Alexander Osterwalder (Business Model Generation: A Handbook for Visionaries, Game Changers, and Challengers (The Strategyzer Series 1))
Power is defined as an ability to do qualitative work with a quantitative passion, backed by a compelling conviction, directed by a propelling purpose, fulfilling a divine destiny. That is power!
Israelmore Ayivor (Michelangelo | Beethoven | Shakespeare: 15 Things Common to Great Achievers)
Quantitative changes suddenly become qualitative changes. From all of Marxism, which I once thought attractive enough, I find only this dictum remaining in the realm of my opinions. Water grows colder and colder and colder, and suddenly it's ice. The day grows darker and darker, and suddenly it's night. Man ages and ages, and suddenly he's dead. Quantitative changes suddenly become qualitative changes; differences in degree lead to differences in kind.
John Barth
qualitative change is only produced by long-term quantitative accumulation.
Liu Cixin (The Dark Forest (Remembrance of Earth’s Past, #2))
A population of four million is not quantitatively but qualitatively different from an individual, because it involves systems of interaction among the individuals.
Paul Watzlawick (Change: Principles of Problem Formation and Problem Resolution)
All so-called ‘quantitative’ data, when scrutinized, turn out to be composites of ‘qualitative’ – i.e., contextually located and indexical – interpretations produced by situated researchers, coders, government officials and others. The
Anthony Giddens (The Constitution of Society: Outline of the Theory of Structuration)
A man's death makes everything certain about him. Of course, secrets may die with him. And of course, a hundred years later somebody looking through some papers may discover a fact which throws a totally different light on his life and of which all the people who attended his funeral were ignorant. Death changes the facts qualitatively but not quantitatively. One does not know more facts about a man because he is dead. But what one already knows hardens and becomes definite. We cannot hope for ambiguities to be clarified, we cannot hope for further change, we cannot hope for more. We are now the protagonists and we have to make up our minds.
John Berger
We will endeavor to halt the Industrial Revolution before it is too late, to regulate population at a reasonable point, to eventually replace quantitative money with qualitative money, to decentralize, to conserve resources. The Industrial Revolution is primarily a virus revolution, dedicated to controlled proliferation of identical objects and persons. You are making soap, you don't give a shit who buys your soap, the more the soapier. And you don't give a shit who makes it, who works in your factories. Just so they make soap.
William S. Burroughs
Man is saved if he opens himself to God and to others, even if he is not clearly aware that he is doing so. This is valid for Christians and non-Christians alike -- for all people. . . . We can no longer speak properly of a profane world. A qualitative and intensive approach replaces a quantitative and extensive one.
Gustavo Gutiérrez (A Theology of Liberation)
Be fruitful. God’s command in Genesis 1:28 is most often understood as referring to procreation, but filling the earth with people is only part of the meaning. The Hebrew word for fruitful means more than just sexual reproduction; it refers to being fruitful in either a literal or a figurative sense. Fruitfulness can be qualitative in nature as well as quantitative. Mankind has never had a problem being procreative—a current global population of over six billion is proof of that—but we do have a problem with being fruitful in the other ways God desires. Essentially, being fruitful means releasing our potential. Fruit is an end product. An apple tree may provide cool shade and be beautiful to look at, but until it produces apples it has not fulfilled its ultimate purpose. Apples contain the seeds of future apple trees and, therefore, future apples. However, apples also have something else to offer: a sweet and nourishing food to satisfy human physical hunger. In this sense, fruit has a greater purpose than simply reproducing; fruit exists to bless the world. Every person is born with a seed of greatness. God never tells us to go find seed; it is already within us. Inside each of us is the seed potential for a full forest—a bumper crop of fruit with which to bless the world. We each were endowed at birth with a unique gift, something we were born to do or become that no one else can achieve the way we can. God’s purpose is that we bear abundant fruit and release the blessings of our gift and potential to the world.
Myles Munroe (The Purpose and Power of Love & Marriage)
MANAGING STRICTLY BY NUMBERS IS LIKE PAINTING BY NUMBERS Some things that you want to encourage will be quantifiable, and some will not. If you report on the quantitative goals and ignore the qualitative ones, you won’t get the qualitative goals, which may be the most important ones. Management purely by numbers is sort of like painting by numbers—it’s strictly for amateurs. At HP, the company wanted high earnings now and in the future. By focusing entirely on the numbers, HP got them now by sacrificing the future.
Ben Horowitz (The Hard Thing About Hard Things: Building a Business When There Are No Easy Answers)
When you ignore quantitative measurements for a bit, you can get back to qualitative measurements.
Austin Kleon (Keep Going: 10 Ways to Stay Creative in Good Times and Bad)
The desire after hoarding is in its very nature unsatiable. In its qualitative aspect, or formally considered, money has no bounds to its efficacy, i.e., it is the universal representative of material wealth, because it is directly convertible into any other commodity. But, at the same time, every actual sum of money is limited in amount, and, therefore, as a means of purchasing, has only a limited efficacy. This antagonism between the quantitative limits of money and its qualitative boundlessness, continually acts as a spur to the hoarder in his Sisyphus-like labour of accumulating. It is with him as it is with a conqueror who sees in every new country annexed, only a new boundary.
Karl Marx (Capital: A Critique of Political Economy)
Rabbinic literature can be studied in two different ways, in two directions, one might say. It can be studied quantitatively or qualitatively - or, as my father once put it, horizontally or vertically. The former involves covering as much material as possible, without attempting to wrest it from it all its implications and intricacies; the latter involves confining oneself to one single area until it is exhaustively covered, and then going on to new material.
Chaim Potok (The Chosen (Reuven Malther, #1))
Qualitative and quantitative research with adults and children reporting ritual abuse has found that it occurs alongside other forms of organised abuse, particularly the manufacture of child abuse images (Scott 2001, Snow and Sorenson 1990, Waterman et al. 1993), and hence subsuming such non-ritualistic experiences under the moniker ‘ritual abuse’ is misleading at best and incendiary at worst. Moreover, it is unclear why an abusive group that invokes a religious or metaphysical mandate to abuse children should be considered as largely distinct from an abusive group that invokes a non-religious rationale to do so. The presumption evident amongst some authors writing on ritual abuse that a professed spiritual motivation for abusing children necessarily reflects the offenders actual motivation seems naïve at best, and at worst it risks colluding with the ways in which abusive groups obfuscate responsibility for their actions.
Michael Salter (Organised Sexual Abuse)
When you ignore quantitative measurements for a bit, you can get back to qualitative measurements. Is it good? Really good? Do you like it? You can also focus more on what the work does that can’t be measured. What it does to your soul.

I isolate a grove from my root network for a moment and enjoy the night as a human might, small in size but intense in outlook, entirely and pleasurably alert to nothing beyond my immediate surroundings, a luxury I can take only for a moment, but it is amazing how being small is a qualitative rather than a quantitative difference.

Sunday Adelaja
Between an American millionaire, a Caesar or Napoleon, or Lenin and the Socialist boss of a village there is no qualitative difference, only quantitative.
Fernando Pessoa (The Book of Disquiet: The Complete Edition)
Funny thing, falling in love. You can't quite explain the difference between this--kissing the girl you love, having sex with the girl you love--and all the kissing and all the sex that came before. You can't describe the difference between her flesh and that flesh, her hips and their hips, her gasp and those gasps. You can't parse the qualitative and quantitative aspects of the experience, the units that make up the whole, any more than you, the untrained viewer, can explain why the Mona Lisa is the Mona fucking Lisa. You just stand back and take it in and say, Wow, so this is art. You lie back in your bed, you hold her next to your chest, her ribs next to your ribs, her breath and your breath, and you say, So this is love.

It is when we go beyond instinct that we seem most idiosyncratically human. Perhaps, as Darwin suggested, the difference is one of degree rather than kind; it is quantitative, not qualitative.

Finally, another large-scale study [of false rape allegations] was conducted in Australia, with the 850 rapes reported to the Victoria police between 2000 and 2003 (Heenan & Murray, 2006). Using both quantitative and qualitative methods, the researchers examined 812 cases with sufficient information to make an appropriate determination, and found that only 2.1% of these were classified as false reports. All of these complainants were then charged or threatened with charges for filing a false police report." Lonsway, K. A., Archambault, J., & Lisak, D. (2009).

We know that the first step towards attaining intellectual mastery of our environment is to discover generalizations, rules and laws which bring order into chaos. In doing this we simplify the world of phenomena; but we cannot avoid falsifying it, especially if we are dealing with the process of development and change. What we are concerned with is discerning a qualitative alteration, and as a rule in doing so we neglect, at any rate to begin with, a quantitative factor.
Sigmund Freud (Análisis terminable e interminable)
One of the many signs of verbal virtuosity among intellectuals is the repackaging of words to mean things that are not only different from, but sometimes the direct opposite of, their original meanings. 'Freedom' and 'power' are among the most common of these repackaged words. The basic concept of freedom as not being subjected to other people's restrictions, and of power as the ability to restrict other people's options have both been stood on their heads in some of the repackaging of these words by intellectuals discussing economic issues. Thus business enterprises who expand the public's options, either quantitatively (through lower prices) or qualitatively (through better products) are often spoken of as 'controlling' the market, whenever this results in a high percentage of consumers choosing to purchase their particular products rather than the competing products of other enterprises. In other words, when consumers decide that particular brands of products are either cheaper or better than competing brands of those products, third parties take it upon themselves to depict those who produced these particular brands as having exercised 'power' or 'control.' If, at a given time, three-quarters of the consumers prefer to buy the Acme brand of widgets to any other brand, then Acme Inc. will be said to 'control' three-quarters of the market, even though consumers control 100 percent of the market, since they can switch to another brand of widgets tomorrow if someone else comes up with a better widget, or stop buying widgets altogether if a new product comes along that makes widgets obsolete. ....by saying that businesses have 'power' because they have 'control' of their markets, this verbal virtuosity opens the way to saying that government needs to exercise its 'countervailing power' (John Kenneth Galbraith's phrase) in order to protect the public. Despite the verbal parallels, government power is in fact power, since individuals do not have a free choice as to whether or not to obey government laws and regulations, while consumers are free to ignore the products marketed by even the biggest and supposedly most 'powerful' corporations in the world.
Thomas Sowell (Intellectuals and Society)
If it really were the case, as popular opinion has tried to establish, that the genius were separated from ordinary men by a thick wall through which no sound could penetrate, then all understanding of the efforts of genius would be denied to ordinary men, and their works would fail to make any impression on them. All hopes of progress depend on this being untrue. And it is untrue. The difference between men of genius and the others is quantitative not qualitative, of degree not of kind.
Otto Weininger (Sex and Character: An Investigation of Fundamental Principles)
Given the unconventional nature and scale of the problems we are facing today, there is real need to value our artists . Creative collaborations can bridge the best talents we have in both the quantitative and qualitative domains and inspire solutions .

Generally, hypothesis statements use the format: We believe [this statement is true]. We will know we’re [right/wrong] when we see the following feedback from the market: [qualitative feedback] and/or [quantitative feedback] and/or [key performance indicator change].
Jeff Gothelf (Lean UX: Applying Lean Principles to Improve User Experience)
There is no qualitative or quantitative measurement for pain. It is simply there--sharp or dull, shooting or stabbing, bearable or excruciating, local or general, it is unexplained, uninvited, unavoidable. It takes command. It is all-encompassing, implacable, exigent.
Elisabeth Elliot (Love Has A Price Tag)
Praying through is all about intensity. It’s not quantitative; it’s qualitative. Drawing prayer circles involves more than words; it’s gut-wrenching groans and heartbreaking tears. Praying through doesn’t just bend God’s ear; it touches the heart of your heavenly Father.
Mark Batterson (The Circle Maker (Enhanced Edition): Praying Circles Around Your Biggest Dreams and Greatest Fears)
A Nazi initiation into the upper reaches of the SS was to gouge out the eye of a pet cat after feeding the cat and cuddling it for a month. This exercise was designed to eliminate all traces of pity-poison and mold a full Übermensch. There is a very sound magical postulate involved: the practitioner achieves superhuman status by performing some atrocious, revolting, subhuman act. In Morocco, magic men gain power by eating their own excrement. But dig out Ruski’s eyes? Stack bribes to the radioactive sky. What does it profit a man? I could not occupy a body that could dig out Ruski’s eyes. So WHO gained the whole world? I didn’t. Any bargain involving exchange of qualitative values like animal love for quantitative advantage is not only dishonorable, as wrong as a man can get, it is also foolish. Because YOU get nothing. You have sold your YOU.
William S. Burroughs (The Cat Inside)
The human mind is an incredible thing. It can conceive of the magnificence of the heavens and the intricacies of the basic components of matter. Yet for each mind to achieve its full potential, it needs a spark. The spark of enquiry and wonder. Often that spark comes from a teacher. Allow me to explain. I wasn’t the easiest person to teach, I was slow to learn to read and my handwriting was untidy. But when I was fourteen my teacher at my school in St Albans, Dikran Tahta, showed me how to harness my energy and encouraged me to think creatively about mathematics. He opened my eyes to maths as the blueprint of the universe itself. If you look behind every exceptional person there is an exceptional teacher. When each of us thinks about what we can do in life, chances are we can do it because of a teacher. [...] The basis for the future of education must lie in schools and inspiring teachers. But schools can only offer an elementary framework where sometimes rote-learning, equations and examinations can alienate children from science. Most people respond to a qualitative, rather than a quantitative, understanding, without the need for complicated equations. Popular science books and articles can also put across ideas about the way we live. However, only a small percentage of the population read even the most successful books. Science documentaries and films reach a mass audience, but it is only one-way communication.
Stephen Hawking (Brief Answers to the Big Questions)
Some readers may find it a curious or even unscientific endeavour to craft a criminological model of organised abuse based on the testimony of survivors. One of the standard objections to qualitative research is that participants may lie or fantasise in interview, it has been suggested that adults who report severe child sexual abuse are particularly prone to such confabulation. Whilst all forms of research, whether qualitative or quantitative, may be impacted upon by memory error or false reporting. there is no evidence that qualitative research is particularly vulnerable to this, nor is there any evidence that a fantasy— or lie—prone individual would be particularly likely to volunteer for research into child sexual abuse. Research has consistently found that child abuse histories, including severe and sadistic abuse, are accurate and can be corroborated (Ross 2009, Otnow et al. 1997, Chu et al. 1999). Survivors of child abuse may struggle with amnesia and other forms of memory disturbance but the notion that they are particularly prone to suggestion and confabulation has yet to find a scientific basis. It is interesting to note that questions about the veracity of eyewitness evidence appear to be asked far more frequently in relation to sexual abuse and rape than in relation to other crimes. The research on which this book is based has been conducted with an ethical commitment to taking the lives and voices of survivors of organised abuse seriously.
Michael Salter (Organised Sexual Abuse)
While I call myself an investor, an evolutionary biologist would not be remiss in branding me a “signal decoder.” The only things investors can rely on to assess a company are the signals emitted by it—some direct and others indirect, some comprehensible and others bizarre, some ongoing and others delayed, and some quantitative and others qualitative.
Pulak Prasad (What I Learned About Investing from Darwin)
Stalin’s teachings about gradual, concealed, unnoticeable quantitative changes leading to rapid, radical, qualitative changes permitted Soviet biologists to discover in plants the realization of such qualitative transitions that one species could be transformed into another’… The slide away from truth-directed science had disastrous results in agriculture. It was also humanly disastrous. Biologists who disagreed were shot or imprisoned.
Jonathan Glover (Humanity: A Moral History of the Twentieth Century)
This paradox is resolved when we recognize that advances since 1970 have tended to be channeled into a narrow sphere of human activity having to do with entertainment, communications, and the collection and processing of information. For the rest of what humans care about—food, clothing, shelter, transportation, health, and working conditions both inside and outside the home—progress slowed down after 1970, both qualitatively and quantitatively.

The transformation of a business-as-usual culture into one focused on innovation and driven by design involves activities, decisions, and attitudes. Workshops help expose people to design thinking as a new approach. Pilot projects help market the benefits of design thinking within the organization. Leadership focuses the program of change and gives people permission to learn and experiment. Assembling interdisciplinary teams ensures that the effort is broadly based. Dedicated spaces such as the P&G Innovation Gym provide a resource for longer-term thinking and ensure that the effort will be sustained. Measurement of impacts, both quantitative and qualitative, helps make the business case and ensures that resources are appropriately allocated. It may make sense to establish incentives for business units to collaborate in new ways so that younger talent sees innovation as a path to success rather than as a career risk.
Tim Brown (Change by Design: How Design Thinking Transforms Organizations and Inspires Innovation)
People are qualitatively the same but may differ quantitatively. The quantitative differences are small in biological terms, and they are found to a far greater extent among the individual members of an ethnic group or race than between ethnic groups or races. These are reassuring findings. Any racist ideology that holds that the members of an ethnic group are all alike, or that one ethnic group differs fundamentally from another, is based on false assumptions about our biology.
Steven Pinker (The Blank Slate: The Modern Denial of Human Nature)
If you know a thing only qualitatively, you know it no more than vaguely. If you know it quantitatively—grasping some numerical measure that distinguishes it from an infinite number of other possibilities—you are beginning to know it deeply. You comprehend some of its beauty and you gain access to its power and the understanding it provides. Being afraid of quantification is tantamount to disenfranchising yourself, giving up on one of the most potent prospects for understanding and changing the world.
Carl Sagan (Billions & Billions: Thoughts on Life & Death at the Brink of the Millennium)
Being able to spot bullshit based on data is a critical skill. Decades ago, fancy language and superfluous detail might have served a bullshitter’s needs. Today, we are accustomed to receiving information in quantitative form, but hesitant to question that information once we receive it. Quantitative evidence generally seems to carry more weight than qualitative arguments. This weight is largely undeserved—only modest skill is required to construct specious quantitative arguments. But we defer to such arguments nonetheless. Consequently, numbers offer the biggest bang for the bullshitting buck.
Carl T. Bergstrom (Calling Bullshit: The Art of Skepticism in a Data-Driven World)
Consciousness grew out of the unconscious, psychology out of physiology, the organic world out of the inorganic, the solar system out of the nebulae. On all the rungs of this ladder of development, the quantitative changes were transformed into qualitative. Our thought, including dialectical thought, is only one of the forms of the expression of changing matter. There is place within this system for neither God nor Devil, nor immortal soul, nor eternal norms of laws and morals. The dialectic of thinking, having grown out of the dialectic of nature, possess consequently a thoroughly materialist character.
Leon Trotsky (The ABC of Materialist Dialectics)
Animals at the high end of heartbeat longevity, such as mice, cats, dogs, horses, elephants, and whales, have the capacity for as many as a billion heartbeats within their life spans. Human hearts, on the other hand, can sustain nearly three billion beats in a lifetime. This significant difference in humans’ capacity for longevity demands explanation. The human body’s characteristics allowing for such extended activity on all levels (physical, mental, and spiritual) suggests uniqueness of design and purpose. It argues for a qualitative rather than mere quantitative difference between humans and the rest of Earth’s creatures.
Hugh Ross (Hidden Treasures in the Book of Job (Reasons to Believe): How the Oldest Book in the Bible Answers Today's Scientific Questions)
[…] a student in our class asked disdainfully why quantitative methodologists do not openly criticize qualitative methods. He scoffed, 'They don't even mention it. But in courses in qualitative methods, quantitative methods always come up.' […] I pointed out that the lack of critical remarks and the absence of any mention of qualitative research in 'methods' courses indicate the hegemony of the quantitative approach. Were not his statistics professors making a strong statement about the place of qualitative methods by omitting them entirely? Qualitative researchers, then, have to legitimate their perspective to students in order to break the methodological silence coming from the other side.
Sherryl Kleinman (Emotions and Fieldwork (Qualitative Research Methods))
It will be noticed that the fundamental theorem proved above bears some remarkable resemblances to the second law of thermodynamics. Both are properties of populations, or aggregates, true irrespective of the nature of the units which compose them; both are statistical laws; each requires the constant increase of a measurable quantity, in the one case the entropy of a physical system and in the other the fitness, measured by m, of a biological population. As in the physical world we can conceive the theoretical systems in which dissipative forces are wholly absent, and in which the entropy consequently remains constant, so we can conceive, though we need not expect to find, biological populations in which the genetic variance is absolutely zero, and in which fitness does not increase. Professor Eddington has recently remarked that 'The law that entropy always increases—the second law of thermodynamics—holds, I think, the supreme position among the laws of nature'. It is not a little instructive that so similar a law should hold the supreme position among the biological sciences. While it is possible that both may ultimately be absorbed by some more general principle, for the present we should note that the laws as they stand present profound differences—-(1) The systems considered in thermodynamics are permanent; species on the contrary are liable to extinction, although biological improvement must be expected to occur up to the end of their existence. (2) Fitness, although measured by a uniform method, is qualitatively different for every different organism, whereas entropy, like temperature, is taken to have the same meaning for all physical systems. (3) Fitness may be increased or decreased by changes in the environment, without reacting quantitatively upon that environment. (4) Entropy changes are exceptional in the physical world in being irreversible, while irreversible evolutionary changes form no exception among biological phenomena. Finally, (5) entropy changes lead to a progressive disorganization of the physical world, at least from the human standpoint of the utilization of energy, while evolutionary changes are generally recognized as producing progressively higher organization in the organic world.
Ronald A. Fisher (The Genetical Theory of Natural Selection)
Skill is the connection between life and tools, or life and machines. Once, skill was defined ultimately in qualitative terms: How well did a person work; how good, durable, and pleasing were his products? But as machines have grown larger and more complex, and as our awe of them and our desire for labor-saving have grown, we have tended more and more to define skill quantitatively: How speedily and cheaply can a person work? We have increasingly wanted a measurable skill. And the more quantifiable skills became, the easier they were to replace with machines. As machines replace skill, they disconnect themselves from life; they come between us and life. They begin to enact our ignorance of value—of essential sources, dependences, and relationships.
Wendell Berry (The Art of the Commonplace: The Agrarian Essays of Wendell Berry)
The Objectives and Key Results (OKR) technique is a tool for management, focus, and alignment. As with any tool, there are many ways to use it. Here are the critical points for you to keep in mind when using the tool for product teams in product organizations. Objectives should be qualitative; key results need to be quantitative/measurable. Key results should be a measure of business results, not output or tasks. The rest of the company will use OKRs a bit differently, but for the product management, design, and technology organization, focus on the organization's objectives and the objectives for each product team, which are designed to roll up and achieve the organization's objectives. Don't let personal objectives or functional team objectives dilute or confuse the focus.
Marty Cagan (Inspired: How to Create Tech Products Customers Love (Silicon Valley Product Group))
Objectivity is obsessed with exactness and tends to be rather intolerant of deviation, almost like the jealous God of monotheistic mythologies. But meanings change over time, with the personality of the reader, and with context. Subjectivity challenges the assumption that ideas are fixed and can be controlled; it celebrates the fluid. Modern global discourse tends to look at truth qualitatively: it is either true or false. That which is objective is scientific and true. That which is subjective is mythic and false. Hindu thought, however, looks at truth quantitatively: everyone has access to a slice (bhaga); the one who sees all slices of truth is bhaga-van. Limited truth is mithya. Limitless truth is satya. Satya is about including everything and being whole (purnam). The journey towards limitless truth expands our mind (brahmana).
Devdutt Pattanaik (My Gita)
It is one thing to explain the causal origins of thinking, as science commendably does; it is an entirely different thing to conflate thinking in its formal or rule-governed dimension with its evolutionary genesis. Being conditioned is not the same as being constituted. Such a conflation not only sophistically elides the distinction between the substantive and the formal, it also falls victim to a dogmatic metaphysics that is impulsively blind to its own epistemological and methodological bases qua origins. It is this genetic fallacy that sanctions the demotion of general intelligence as qualitatively distinct to a mere quantitative account of intelligent behaviours prevalent in nature. It should not come as a any surprise that this is exactly the jaded gesture of antihumanism upon whose shoddy pillars today's discourse of posthumanism supports its case. Talk of thinking forests, rocks, worn shoes, and ethereal beings goes hand in hand with the cult of technological singularity, musings on Skynet or the Market as speculative posthuman intelligence, and computers endowed with intellectual intuition. And again, by now it should have become obvious that, despite the seeming antagonism between these two camps - one promoting the so-called egalitarianism of going beyond human conditions by dispensing with the rational resources of critique, the other advancing the speculative aspects of posthuman supremacy on the grounds of the technological overcoming of the human condition - they both in fact belong to the arsenal of today's neoliberal capitalism in its full-on assault on any account of intelligence that may remotely insinuate an ambition for collective rationality and imagination.
Reza Negarestani (Intelligence and Spirit)
The Soviets were not 50% right, they were entirely wrong. They weren’t quantitatively wrong about the amount of variance due to the environment, they were qualitatively wrong about what environmental manipulations could do in the face of built-in universal human machinery. Having said this, though, I now feel no particular impulse to vote Republican. Also, it’s quite possible that someday you could create perfectly unselfish people… if you used sufficiently advanced neurosurgery, drugs, and/or brain-computer interfaces to engineer their brains into a new state that no current human brain occupies.

Eliezer Yudkowsky (Brain, Belief, and Politics (Cato Unbound Book 92011))
The fashion now is to think of universities as industries or businesses. University presidents, evidently thinking of themselves as CEO's, talk of "business plans" and "return on investment," as if the industrial economy could provide an aim and a critical standard appropriate either to education or to research. But this is not possible. No economy, industrial or otherwise, can supply an appropriate aim or standard. Any economy must be either true or false to the world and to our life in it. If it is to be true, then it must be made true, according to a standard that is not economic. To regard the economy as an end or as the measure of success is merely to reduce students, teachers, researchers, and all they know or learn to merchandise. It reduces knowledge to "property" and education to training for the "job market." If, on the contrary, [Sir Albert] Howard was right in his belief that health is the "one great subject," then a unifying aim and a common critical standard are clearly implied. Health is at once quantitative and qualitative; it requires both sufficiency and goodness. It is comprehensive (it is synonymous with "wholeness"), for it must leave nothing out. And it is uncompromisingly local and particular; it has to do with the sustenance of particular places, creatures, human bodies, and human minds. If a university began to assume responsibility for the health of its place and its local constituents, then all of its departments would have a common aim, and they would have to judge their place and themselves and one another by a common standard. They would need one another's knowledge. They would have to communicate with one another; the diversity of specialists would have to speak to one another in a common language. And here again Howard is exemplary, for he wrote, and presumably spoke, a plain, vigorous, forthright English-- no jargon, no condescension, no ostentation, no fooling around.
Wendell Berry
Trinitarian monotheism is not a matter of the number three. It is a qualitative and not a quantitative characterization of God. It is an attempt to speak of the living God, the God in whom the ultimate and the concrete are united. The number three has no specific significance in itself, although it comes nearest to an adequate description of life-processes. Even in the history of the Christian doctrine of the trinity there have been vascillations between trinitarian and binitarian emphasis (the discussion about the position of the Holy Ghost) and between trinity and quaternity (the question about the relation of the Father to the common divine substance of the three personae). The trinitarian problem has nothing to do with the trick question how one can be three and three be one. The answer to this question is given in every life-process. The trinitarian problem is the problem of the unity between ultimacy and concreteness in the living God. Trinitarian monotheism is concrete monotheism, the affirmation of the living God.
Paul Tillich (Systematic Theology, Vol 1)
The process of simplifying man's environment and rendering it increasingly elemental and crude has a cultural as well as a physical dimension. The need to manipulate immense urban populations—to transport, feed, employ, educate and somehow entertain millions of densely concentrated people—leads to a crucial decline in civic and social standards. A mass concept of human relations—totalitarian, centralistic and regimented in orientation—tends to dominate the more individuated concepts of the past. Bureaucratic techniques of social management tend to replace humanistic approaches. All that is spontaneous, creative and individuated is circumscribed by the standardized, the regulated and the massified. The space of the individual is steadily narrowed by restrictions imposed upon him by a faceless, impersonal social apparatus. Any recognition of unique personal qualities is increasingly surrendered to the manipulation of the lowest common denominator of the mass. A quantitative, statistical approach, a beehive manner of dealing with man, tends to triumph over the precious individualized and qualitative approach which places the strongest emphasis on personal uniqueness, free expression and cultural complexity.
Murray Bookchin (Post-Scarcity Anarchism (Working Classics))
As Descartes said to his close correspondent, Marin Mersenne, “I may tell you, between ourselves, that these six Meditations contain all the foundations of my physics. But please do not tell people, for that might make it harder for supporters of Aristotle to approve of them. I hope that readers will gradually get used to my principles, and recognize their truth, before they notice that they destroy the principles of Aristotle” (18 January 1641). The Meditations attempts a complete intellectual revolution: the replacement of Aristotelian philosophy with a new philosophy in order to replace Aristotelian science with a new science. For a 17th-century Aristotelian, a body is matter informed by substantial and accidental forms, and change is explained by the gain or loss of such forms: in mutation by the acquisition of a substantial form, and in what Aristotelians would call true motion (that is, augmentation and diminution, alteration, or local motion) by the successive acquisition of places or of qualitative or quantitative forms. The mechanist program consisted in doing away with qualitative forms and reducing all changes to something mathematically quantifiable: matter in motion. As Descartes said in The World, not only the four qualities called heat, cold, moistness, and dryness, “but also all the others
Roger Ariew (Modern Philosophy: An Anthology of Primary Sources)
The first stage can be called stage of potential power… A nation is not industrial. Its people are primarily agricultural and the great majority of them are rural… Such a nation may be very powerful in a world where no nation is industrial. But compared to any industrial nation, even a small one, its power is slight... The second stage of the power transition is the stage of the transitional growth… to an industrial stage… its power grows rapidly relative to that of the other pre-industrial nations whom it leaves behind. Fundamental changes take places within the nation. There is great growth in industry and in the cities… Large number of people move out of farming and into industry and service occupations… They move from the country-side to the growing cities. Productivity per man-hour rises, the national income goes up sharply… Nationalism runs high and sometimes finds expression in aggressive action toward the outside… So many of these changes have the effect of increasing the ability of the nation`s representatives to influence the behavior of other nations, i.e. of increasing the nation`s power… The changes that occur at the beginning of the industrialization process are qualitative, not just quantitative. It is these first fundamental changes that brings the great spurt in national power. Of course, the speed at which a nation gains power depends largely upon the speed with which she industrializes, and both these factors have a great influence on the degree to which the rise of a new power upsets the international community (302-304).

This is the pattern: poor quantitative results force us to declare failure and create the motivation, context, and space for more qualitative research. These investigations produce new ideas—new hypotheses—to be tested, leading to a possible pivot. Each pivot unlocks new opportunities for further experimentation, and the cycle repeats. Each time we repeat this simple rhythm: establish the baseline, tune the engine, and make a decision to pivot or persevere.

With the onset of the war, each belligerent eagerly scanned its competitors and allies for aspects of state management and intervention in the war economy which could be imitated. The capitalist sectors, appeased by enormous profits and inspired no doubt also by patriotism, raised no objections. The result was a qualitative and quantitative expansion of the role of the state which has never been fully reversed–for though wartime arrangements were sometimes abandoned with peace, in virtually every case they were eventually adopted again, usually permanently.

Consequently, medical data theft can lead to a variety of long-term problems including damaged credit, misdiagnosed illnesses, and unwarranted medical charges. Personal data has become such a valuable commodity that it's outpacing stolen credit cards on the black markets.

when a computer program beats a grandmaster at chess, the two are not using even remotely similar algorithms. The grandmaster can explain why it seemed worth sacrificing the knight for strategic advantage and can write an exciting book on the subject. The program can only prove that the sacrifice does not force a checkmate, and cannot write a book because it has no clue even what the objective of a chess game is. Programming AGI is not the same sort of problem as programming Jeopardy or chess. An AGI is qualitatively, not quantitatively, different from all other computer programs.

Dans ses versions les plus stylisées, l’arabesque à forme végétale n’a plus qu’une lointaine ressemblance avec une plante. En revanche, elle transcrit parfaitement, en termes visuels, les lois du rythme : son déroulement est continu comme celui d’une vague, avec des phases contrastantes aux multiples résonances. Le dessin n’est pas nécessairement symétrique mais, pour compenser, il comporte toujours des alternances dont le caractère rythmique est accentué par le fait que les pleins et les vides sont esthétiquement équivalents. A proprement parler, le rythme n’appartient pas à l’espace mais au temps dont il est la mesure non pas quantitative mais qualitative. C’est par l’intermédiaire du mouvement que le rythme est rétabli dans la dimension de l’espace.

Le véritable objet de l’architecture islamique, c’est l’espace comme tel, dans sa plénitude indifférenciée. Les arcades et leur majestueuse ampleur – elles dépassent le plein cintre et se dilatent légèrement en fer à cheval – suffisent pour rendre cette qualité manifeste. Ce n’est pas pour rien qu’en arabe le nom de l’arcade, rawq (au pluriel riwaq) est devenu le synonyme de beau, gracieux et pur. Une simple arcade bâtie selon de justes proportions possède la vertu de transformer l’espace d’une réalité purement quantitative en une réalité qualitative. Et l’on sait que l’art islamique a développé une grande variété de formes d’arc, qui s’annoncent déjà dans l’architecture omeyyade et dont deux sont les plus typiques : l’arc en fer à cheval, qui trouve son expression la plus parfaite dans l’art maghrébin, et l’arc « en carène », qui caractérise l’art persan. L’une et l’autre de ces formes combinent les deux qualités de calme statique et de légèreté ascendante. L’arc persan est à la fois généreux et gracieux ; il s’élève sans aucun effort, comme la flamme calme d’une lampe à l’huile protégée du vent. Quant à l’arc maghrébin, il se caractérise par son expansion extrême, souvent contenue par un cadre rectangulaire, d’où une synthèse de stabilité et d’ampleur.

I am surprised at how often researchers fail to draft a title early in the development of their projects. In my opinion, the working or draft title becomes a major road sign in research—a tangible idea that the researcher can keep refocusing on and changing as the project goes on (see Glesne & Peshkin, 1992).

Unfortunately, computer knowledge, because it must be processed and programmed, cannot remain constantly in touch, like the human brain, with the unceasing flow of reality; for only a small part of experience can be arrested for extraction and expression in abstract symbols. Changes that cannot be quantitatively measured or objectively observed, such changes as take place constantly all the way from the atom to the living organism, are outside the scope of the computer. For all its fantastic rapidity of operation, its components remain incapable of making qualitative responses to constant organic changes.
Lewis Mumford (The Pentagon of Power (The Myth of the Machine, Vol 2))
Modern global discourse tends to look at truth qualitatively: it is either true or false. That which is objective is scientific and true. That which is subjective is mythic and false. Hindu thought, however, looks at truth quantitatively: everyone has access to a slice (bhaga); the one who sees all slices of truth is bhaga-van. Limited truth is mithya. Limitless truth is satya. Satya is about including everything and being whole (purnam). The journey towards limitless truth expands our mind (brahmana). The Gita itself values subjectivity:

There was a discussion about success, and broad agreement that qualitative results were more significant than quantitative ones. Success should be defined by three questions: did centres open, did people vote and did it become ‘ordinary’ for people to do so?

Third Wave technology will also change how we measure success in the classroom. What good is an annual standardized test, after all, once teachers and parents can get detailed reports with a wide range of metrics, comparing their students on a regular basis to others in their class or school or state? In this way, big data on individual students will do for education what standardized testing never quite could: bring quantitative precision to a qualitative learning process.
Steve Case (The Third Wave: An Entrepreneur's Vision of the Future)
Whether it’s anthropology or sociology or geography, social scientists are often asked – no, required – early in their careers, to choose between humanistic and scientific approaches to the subject matter of their discipline and between collecting and analyzing qualitative or quantitative data. Even worse, they are taught to equate science with quantitative data and quantitative analysis and humanism with qualitative data and qualitative analysis. This denies the grand tradition of qualitative approaches in all of science, from astronomy to zoology. When Galileo first trained his then-brand-new telescope on the moon, he noticed what he called lighter and darker areas. The large dark spots had, Galileo said, been seen from time immemorial and so he said, “These I shall call the ‘large’ or ‘ancient’ spots.” He also wrote that the moon was “not smooth, uniform, and precisely spherical” as commonly believed, but “uneven, rough, and full of cavities and prominences,” much like the Earth. No more qualitative description was ever penned

MANAGING STRICTLY BY NUMBERS IS LIKE PAINTING BY NUMBERS Some things that you want to encourage will be quantifiable, and some will not. If you report on the quantitative goals and ignore the qualitative ones, you won’t get the qualitative goals, which may be the most important ones. Management purely by numbers is sort of like painting by numbers—it’s strictly for amateurs. At HP, the company wanted high earnings now and in the future. By focusing entirely on the numbers, HP got them now by sacrificing the future. Note that there were many numbers as well as more qualitative goals that would have helped:   Was our competitive win rate increasing or declining?   Was customer satisfaction rising or falling?   What did our own engineers think of the products? By managing the organization as though it were a black box, some divisions at HP optimized the present at the expense of their downstream competitiveness. The company rewarded managers for achieving short-term objectives in a manner that was bad for the company. It would have been better to take into account the white box. The white box goes beyond the numbers and gets into how the organization produced the numbers. It penalizes managers who sacrifice the future for the short term and rewards those who invest in the future even if that investment cannot be easily measured. CLOSING THOUGHT It is easy to see that there are many ways for leaders to be misinterpreted. To get things right, you must recognize that anything you measure automatically creates a set of employee behaviors. Once you determine the result you want, you need to test the description of the result against the employee behaviors that the description will likely create. Otherwise, the side-effect behaviors may be worse than the situation you were trying to fix.
Ben Horowitz (The Hard Thing About Hard Things: Building a Business When There Are No Easy Answers)
This is why you may need to blend quantitative and qualitative analysis. Our friend John Lilly likes to distinguish between “genius-driven design” (e.g., Apple) and “data-driven design” (e.g., Google). Both approaches have their strengths and weaknesses. Data-driven design is great at optimizing products with incremental changes, but it could steer you to the top of a local hill rather than the highest peak. Genius-driven design may be the only way to build a revolutionary product, but it usually needs to be supplemented with data-driven refinement
Reid Hoffman (Blitzscaling: The Lightning-Fast Path to Building Massively Valuable Companies)
In chess one realises that all education is ultimately self education. This idea is a timely consideration in our data driven world. Chess lends itself to structural information and quantitive analysis in a range of ways. For instance the numerical value of the pieces, databases of millions of games, computerised evaluation functions and the international rating system. However, the value of the experience of playing the game is more qualitative than quantitive. Like any competitive pursuit or sport, chess is an elaborate pretext for the production of stories. The benign conceit of rules and points and tournaments generates a narrative experience in which you are at once co-director, actor and spectator. Chess is education in the literal sense of bringing forth, and it is self education because our stories about a game emerge as we play it, as we try to achieve our goals, just as they do in real life. Chess stories are of our own making and they are often about challenges we overcame or failed to overcome. Every chess player knows the experience of encountering a vexed colleague whose desperate to share their tragic tale in which they were “completely winning!” until they screwed up and lost. And yet we also know tougher characters who recognise that taking resolute responsibility for your mistakes, no matter how painful, is the way to grow as a person and a player. As the child psychologist Bruno Bettelheim says: "we grow, we find meaning in life and security in ourselves by having understood and solved personal problems on our own, not by having them explained to us by others”.

John Dewey (The Collected Works of John Dewey: The Complete Works PergamonMedia)
The tragedy of the Western mind, beautifully described by Koyré, is a direct consequence of the stark Cartesian division between mind and world. We discover the “certain principles of physical reality,” said Descartes, “not by the prejudices of the senses, but by the light of reason, and which thus possess so great evidence that we cannot doubt of their truth.”7 Since the real, or that which actually exists external to ourselves, was in his view only that which could be represented in the quantitative terms of mathematics, Descartes concluded that all qualitative aspects of reality could be traced to the deceitfulness of the senses. It was this logical sequence that led Descartes to posit the existence of two categorically different domains of existence for immaterial ideas—the res extensa and the res cognitans, or the “extended substance” and the “thinking substance.” Descartes defined the extended substance as the realm of physical reality within which primary mathematical and geometrical forms reside and the thinking substance as the realm of human subjective reality. Given that Descartes distrusted the information from the senses to the point of doubting the perceived results of repeatable scientific experiments, how did he conclude that our knowledge of the mathematical ideas residing only in mind or in human subjectivity was accurate, much less the absolute truth? He did so by making a leap of faith—God constructed the world, said Descartes, in accordance with the mathematical ideas that our minds are capable of uncovering in their pristine essence. The truths of classical physics as Descartes viewed them were quite literally “revealed” truths, and it was this seventeenth-century metaphysical presupposition that became in the history of science what we term the “hidden ontology of classical epistemology.

Then there is the extraordinary marriage of observation and mathematics. Mankind, and for some perhaps sociological reason it has been mostly man kind, has developed a sinewy language of the utmost rigour and austerity that has proved to be the perfect tool for teasing out objectively the consequences of an imaginative qualitative leap or of adding spine to a whim so that it can stand up to the harshness of quantitative comparison of prediction with observation. I hasten to add that mathematics does not appear explicitly in this book, but it does lie as a hidden deep foundation beneath it.

The first, or predictive, approach could also be called the qualitative approach, since it emphasizes prospects, management, and other nonmeasurable, albeit highly important, factors that go under the heading of quality. The second, or protective, approach may be called the quantitative or statistical approach, since it emphasizes the measurable relationships between selling price and earnings, assets, dividends, and so forth. Incidentally, the quantitative method is really an extension—into the field of common stocks—of the viewpoint that security analysis has found to be sound in the selection of bonds and preferred stocks for investment. In our own attitude and professional work we were always committed to the quantitative approach. From the first we wanted to make sure that we were getting ample value for our money in concrete, demonstrable terms. We were not willing to accept the prospects and promises of the future as compensation
Benjamin Graham (The Intelligent Investor)
To us the only acceptable point of view appears to be one that recognizes both sides of reality — the quantitative and the qualitative, the physical and the psychical — as compatible with each other, and can embrace them simultaneously. It would be most satisfactory if physics and psyche (i.e., matter and mind) could be viewed as complementary aspects of the same reality.
Wolfgang Pauli
physicists traditionally choose to deal with systems and phenomena that are very different from those in history. Physicists tend to choose very simple systems with few interacting components (such as the solar system, the hydrogen atom, etc.) or systems consisting of a huge number of identical components (as in thermodynamics). As a result, very precise quantitative predictions can be made and empirically tested. But even in physical applications such systems are rare, and in social sciences only very trivial questions can be reduced to such simplicity. Real societies always consist of many qualitatively and quantitatively different agents interacting in very complex ways.
