Rene Descartes Philosophy Quotes

I suppose therefore that all things I see are illusions; I believe that nothing has ever existed of everything my lying memory tells me. I think I have no senses. I believe that body, shape, extension, motion, location are functions. What is there then that can be taken as true? Perhaps only this one thing, that nothing at all is certain.

I desire to live in peace and to continue the life I have begun under the motto 'to live well you must live unseen

Dubito, ergo cogito, ergo sum. (English: "I doubt, therefore I think, therefore I am")

Dubium sapientiae initium. (Doubt is the origin of wisdom.)

But I cannot forget that, at other times I have been deceived in sleep by similar illusions; and, attentively considering those cases, I perceive so clearly that there exist no certain marks by which the state of waking can ever be distinguished from sleep, that I feel greatly astonished; and in amazement I almost persuade myself that I am now dreaming.

Whatever I have up till now accepted as most true and assured I have gotten either from the senses or through the senses. But from time to time I have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once.

Some years ago I was struck by the large number of falsehoods that I had accepted as true in my childhood, and by the highly doubtful nature of the whole edifice that I had subsequently based on them. I realized that it was necessary, once in the course of my life, to demolish everything completely and start again right from the foundations if I wanted to establish anything at all in the sciences that was stable and likely to last.

Very few of us can now place ourselves in the mental condition in which even such philosophers as the great Descartes were involved in the days before Newton had announced the true laws of the motion of bodies.

The analytical geometry of Descartes and the calculus of Newton and Leibniz have expanded into the marvelous mathematical method—more daring than anything that the history of philosophy records—of Lobachevsky and Riemann, Gauss and Sylvester. Indeed, mathematics, the indispensable tool of the sciences, defying the senses to follow its splendid flights, is demonstrating today, as it never has been demonstrated before, the supremacy of the pure reason.

I think, therefore I am? No, I simply am. I am. I am. I am. I will still be if I didn't think. In fact, it is only then that I would step into a different dimension of consciousness. Yes, I will still be if I didn't think. I will still be if I stopped breathing. I will still be because you still are. My words are written and you are receiving them. We are dancing. We are making love. And when you stop reading them, they will still be because nothing ever truly ceases to exist. There is not a thing that is not. Every thought, energy, and vibration is recycled. I am and I will continue to be because I manifest as the universe, therefore I will continue to manifest as the universe.

...Although the term Existentialism was invented in the 20th century by the French philosopher Gabriel Marcel, the roots of this thought go back much further in time, so much so, that this subject was mentioned even in the Old Testament. If we take, for example, the Book of Ecclesiastes, especially chapter 5, verses 15-16, we will find a strong existential sentiment there which declares, 'This too is a grievous evil: As everyone comes, so they depart, and what do they gain, since they toil for the wind?' The aforementioned book was so controversial that in the distant past there were whole disputes over whether it should be included in the Bible. But if nothing else, this book proves that Existential Thought has always had its place in the centre of human life. However, if we consider recent Existentialism, we can see it was the French philosopher Jean-Paul Sartre who launched this movement, particularly with his book Being and Nothingness, in 1943. Nevertheless, Sartre's thought was not a new one in philosophy. In fact, it goes back three hundred years and was first uttered by the French philosopher René Descartes in his 1637 Discours de la Méthode, where he asserts, 'I think, therefore I am' . It was on this Cartesian model of the isolated ego-self that Sartre built his existential consciousness, because for him, Man was brought into this world for no apparent reason and so it cannot be expected that he understand such a piece of absurdity rationally.'' '' Sir, what can you tell us about what Sartre thought regarding the unconscious mind in this respect, please?'' a charming female student sitting in the front row asked, listening keenly to every word he had to say. ''Yes, good question. Going back to Sartre's Being and Nothingness it can be seen that this philosopher shares many ideological concepts with the Neo-Freudian psychoanalysts but at the same time, Sartre was diametrically opposed to one of the fundamental foundations of psychology, which is the human unconscious. This is precisely because if Sartre were to accept the unconscious, the same subject would end up dissolving his entire thesis which revolved around what he understood as being the liberty of Man. This stems from the fact that according to Sartre, if a person accepts the unconscious mind he is also admitting that he can never be free in his choices since these choices are already pre-established inside of him. Therefore, what can clearly be seen in this argument is the fact that apparently, Sartre had no idea about how physics, especially Quantum Mechanics works, even though it was widely known in his time as seen in such works as Heisenberg's The Uncertainty Principle, where science confirmed that first of all, everything is interconnected - the direct opposite of Sartrean existential isolation - and second, that at the subatomic level, everything is undetermined and so there is nothing that is pre-established; all scientific facts that in themselves disprove the Existential Ontology of Sartre and Existentialism itself...

I watch Fox news for the comedy, MSNBC when I need to be reminded that mind midgets exist and CNN when I want to check out the latest in media lies and special interest propaganda. On the other 364 days of the year I read the American transcendentalists, David Hume, Rene Descartes, Immanuel Kant, Niccolo Machiavelli and Diogenes of Sinope.

I esteemed Eloquency highly, and was in raptures with poesy; but I thought that both were gifts of nature rather than fruits of study. Those in whom the faculty of Reason is predominant, and who most skillfully dispose their thoughts with a view to render them clear and intelligible, are always the best able to persuade others of the truth of what they lay down, though they should speak only in the language of Lower Brittany, and be wholly ignorant of the rules of Rhetoric; and those whose minds are stored with the most agreeable fancies, and who can give expression to them with the greatest embellishment and harmony, are still the best poets, though unacquainted with the Art of Poetry.
