George Berkeley Idealism Quotes

It is indeed an opinion strangely prevailing amongst men, that houses, mountains, rivers, and in a word all sensible objects have an existence natural or real, distinct from their being perceived by the understanding. But with how great an assurance and acquiescence soever this principle may be entertained in the world; yet whoever shall find in his heart to call it in question, may, if I mistake not, perceive it to involve a manifest contradiction. For what are the forementioned objects but the things we perceive by sense, and what do we perceive besides our own ideas or sensations; and is it not plainly repugnant that any one of these or any combination of them should exist unperceived?' (Berkeley, 1710: 25)

Each species has its own sensory world, which are often very different from each other's sensory world. There is some overlap between these worlds but there are many aspects of one species world which will be completely unknown to members of other species. The human view of the world is only one view and is no more valid than that of any other species.

A significant part of the history of science has been the dethroning of human beings from being the centre of existence. Copernicus and Kepler showed the Earth was not the centre of the universe with everything orbiting the Earth. Darwin showed that the human being is just another animal, which has evolved like all other animals and shares ancestors with all other living species. It is time to dethrone the human view of the world and recognize that it is just another view of the world, no more real or true than the view of any other species.

Our senses have evolved over millions of years in order to help us to survive. They give us information as to whether food is safe to eat, where potential prey may be and whether potential predators are around. They are designed to give us information relevant to our survival. Information not relevant to our survival, will not normally be available to us. Our senses are not designed to give us an accurate objective view of the world. They require a certain amount of energy to operate and human survival requires that energy is not wasted in providing us with information not relevant to our continued survival as a species. It is hardly surprising our senses do not give an accurate or objective view of the world. They are simply not intended for that purpose.

One of the most neglected areas in the philosophy of perception concerns animal senses. It is surprising how many philosophers write abut perception in the apparent belief that humans are the only perceivers in the world. Human senses evolved through the same natural process as other animal senses, so there is no reason to regard human senses as special, or better than other animals senses.
