A Succinct Version of George Berkeley's Arguments Against Material Substances and in Favor of Spirits, Part 1

We perceive material objects like mountains, rivers, houses, and so forth; but all we perceive are our own ideas or sensations, and so the material objects like mountains, rivers, houses and so forth that we perceive are our own ideas or sensations. Berkeley in this regard states thus: “For what are the aforementioned objects but the things we perceive by sense? And what do we perceive besides our own ideas or sensations?”

Representationalism, however, would posit that our sensations bear resemblance to the material objects of our perception. Berkeley denies this assertion. He does not allow that our sensations or ideas bear any resemblance to extra-mental material substances. Berkeley states in this regard as follows: “But, you say, though the ideas themselves do not exist without the mind, yet there may be things like them of which they are copies or resemblances, which things exist without the mind in an unthinking substance. I answer, an idea can be like nothing but an idea.”

Berkeley is also against the possible view that material things can be the cause of our ideas. In the first place, the existence of material things are not necessary for our possession of ideas, which in any case we can derive from say, dreams. Berkeley states in this regard, “Hence it is evident (that) the supposition of external bodies is not necessary for the producing (of) our ideas, since it is granted they are produced sometimes and might possibly be produced always in the same order we see them in at presence without their occurrence.” Secondly, our ideas do not source from material things because philosophers are yet to figure out the relationship between bodies and minds. Berkeley states in this regard thus: “for though we give the materialists their external bodies, they by their own confession are never the nearer knowing how our ideas are produced, since they admit themselves unable to comprehend in what manner body can act upon spirit or how it is possible it should imprint any idea in the mind.”

For Berkeley, mind-independent material things do not exist. For him, when the term “exist” is applied to material things, it simply means that such material things are being perceived. Berkeley states thus: “The table I write on, I say, exists; that is, I see and feel it; and if I were out of my study I should say it existed – meaning by that that if I was in my study I might perceive it, or that some other spirit actually does perceive it. There was an odor; that is, it was smelled; there was a sound, that is to say, it was heard; a color or figure, and it was perceived by sight or touch. This is all I can understand by these and the like expressions.”

Berkeley underscores the aforementioned by stating with regard to material (sensible) things: “And is it not plainly repugnant that any one of these or a combination of them should exist unperceived?” It is in this regard that one questions if sensible things disappear as soon as we are not presently perceiving them. Recall in any case what Berkeley has said concerning the “existence” of the table he writes on in his study, when he leaves the study: “some other spirit actually does perceive it.” It becomes clear in view of the foregoing that there are no circumstances in which Berkeley would allow for a demarcation between material objects and our sensations. He states in this regard thus: “In truth, the object and the sensation are the same thing and cannot be abstracted from each other.”
