John Locke And Substance Essay, Research Paper

In his essay, ?A Supposition of He Knows Not What,? John Locke offers the

reader an intriguing view of substances and ideas. He argues for the existence

of substances in our world because there must logically be something greater

than the ideas and thoughts that occupy our minds. His argument for their

existence maintains that we cannot see substances in our realms, but we can

perceive them and note their effects on other things around us. Locke first

states that there are too many ideas in the world to stand alone. We cannot see

these ideas that form in our minds, but we know that the ideas we have cannot

persists as one single idea, because everything we think is ?a complication of

many ideas together? (Reality 90). Since the simple ideas we have cannot exist

alone, there must be something larger behind them, and those, Locke asserts, are

substances. Locke maintains that we only see substances in our world as ideas,

for they are too complex for us to perceive. Because of the qualities of our

ideas, we are able to perceive that they exist. The only evidence we have for

this belief is that we can put together ideas on our own, and we can also put

together ideas about substances, therefore these substances must create our

ideas. We perceive substances as ideas, because they are too complicated for our

minds and far from our realm of existence. Therefore, Locke?s notion of

substances reverts back to Plato?s idea of a form: substances are things that

underlie all thought, that we cannot perceive on our own, but must exist in

another place for they form our foundations of thought and ideas.
