Essays on the philosophy of george berkeley

It is evident to any one who takes a survey of the objects of human knowledge, that they are either ideas actually imprinted on the senses, or else such as are perceived by attending to the passions and operations of the mind, or lastly ideas formed by help of memory and imagination, either compounding, dividing, or barely representing those originally perceived in the aforesaid ways. By sight I have the ideas of light and colours with their several degrees and variations.

It is evident to any one who takes a survey of the objects of human knowledge, that they are either ideas actually imprinted on the senses, or else such as are perceived by attending to the passions and operations of the mind, or lastly ideas formed by help of memory and imagination, either compounding, dividing, or barely representing those originally perceived in the aforesaid ways.

By sight I have the ideas of light and colours with their several degrees and variations. By touch I perceive, for example, hard and soft, heat and cold, motion and resistance, and of all these more and less either as to quantity or degree.

Smelling furnishes me with odours; the palate with tastes, and hearing conveys sounds to the mind in all their variety of tone and composition.

And as several of these are observed to accompany each other, they come to be marked by one name, and so to be reputed as one thing. Thus, for example, a certain colour, taste, smell, figure and consistence having been observed to go together, are accounted one distinct thing, signified by the name apple.

Other collections of ideas constitute a stone, a tree, a book, and the like sensible things; which, as they are pleasing or disagreeable, excite the passions of love, hatred, joy, grief, and so forth.

As this passage illustrates, Berkeley does not deny the existence of ordinary objects such as stones, trees, books, and apples. On the contrary, as was indicated above, he holds that only an immaterialist account of such objects can avoid skepticism about their existence and nature.

What such objects turn out to be, on his account, are bundles or collections of ideas. An apple is a combination of visual ideas including the sensible qualities of color and visual shapetangible ideas, ideas of taste, smell, etc.

He does make clear that there are two sides to the process of bundling ideas into objects: Thus, although there is no material world for Berkeley, there is a physical world, a world of ordinary objects. This world is mind-dependent, for it is composed of ideas, whose existence consists in being perceived.

For ideas, and so for the physical world, esse est percipi. In addition to perceived things ideashe posits perceivers, i. Spirits, he emphasizes, are totally different in kind from ideas, for they are active where ideas are passive. This suggests that Berkeley has replaced one kind of dualism, of mind and matter, with another kind of dualism, of mind and idea.

Early life and works

There is something to this point, given Berkeley's refusal to elaborate upon the relation between active minds and passive ideas. Berkeley's dualism, however, is a dualism within the realm of the mind-dependent.

Berkeley believes that once he has established idealism, he has a novel and convincing argument for God's existence as the cause of our sensory ideas. He argues by elimination: What could cause my sensory ideas? Candidate causes, supposing that Berkeley has already established that matter doesn't exist, are 1 other ideas, 2 myself, or 3 some other spirit.

Berkeley eliminates the first option with the following argument PHK Therefore, 3 Ideas are passive, that is, they possess no causal power. The hidden assumption here is that any causing the mind does must be done by willing and such willing must be accessible to consciousness.

Berkeley is hardly alone in presupposing this model of the mental; Descartes, for example, makes a similar set of assumptions. This leaves us, then, with the third option: Berkeley thinks that when we consider the stunning complexity and systematicity of our sensory ideas, we must conclude that the spirit in question is wise and benevolent beyond measure, that, in short, he is God.

Berkeley himself sees very well how necessary this is: Much of the Principles is structured as a series of objections and replies, and in the Three Dialogues, once Philonous has rendered Hylas a reluctant convert to idealism, he devotes the rest of the book to convincing him that this is a philosophy which coheres well with common sense, at least better than materialism ever did.

Berkeley replies that the distinction between real things and chimeras retains its full force on his view. One way of making the distinction is suggested by his argument for the existence of God, examined above: Ideas which depend on our own finite human wills are not constituents of real things.

Not being voluntary is thus a necessary condition for being a real thing, but it is clearly not sufficient, since hallucinations and dreams do not depend on our wills, but are nevertheless not real.1.
