My thanks in advance.
At my Ancient Philosophy class, we are reviewing the Metaphysics, Book VII. I have an Analysis due next week on a fragment of chapter 3. We previously reviewed the Categories, followed by Physics.
I am confused on Aristotle’s definition of Substance, and even more on Subject which he says is “that of which the other things are said, but which is not itself in turn said of any other thing”. This is the first time I read Aristotle’s works, and I find it very difficult. Explain to me as if I was 7 years old
Thank you and God bless.
Substance is
that which exists in itself (or by itself). This is in contrast to
Accident, which means
that which exists in another (i.e. in a substance). Examples of substances: rock, tree, computer, human, chair, etc. Example of accidents: color, height, round, soft, three, running, etc. Substances stand alone and do not have to exist in any other thing except themselves. Accidents, on the other hand, need to exist in something (as color exists in … a rock for example). Accidents can either exist in other accidents, but ultimately they must exist in a substance. Does that make sense?
I’m not 100% confident on how Aristotle is using the word “subject” here (because it can be used in various ways, I believe), but I think he may primarily be using it in the grammatical sense, contrasting it to Predicate. I hope this is correct:
For example, let’s take the sentence:
A dog is an animal.
“A dog” is the subject. And “an animal” is the predicate. This is basic grammar.
Since this is so, we say that “an animal” could
be said of “a dog.” That is, “an animal” can be predicated of “a dog” … in other words, “an animal” can be made into a predicate of the subject “a dog.” And another way to phrase that is, “an animal” could be said of “a dog.”
Likewise, you could say “soft” can be said of “a pillow” (a pillow is soft). Or, “blue” can be said of “the sky” (the sky is blue). Or, “fast” could be said of “my car” (my car is fast).
So, a predicate is (by definition) something said of something else (and that something else, by definition, is called a subject). Likewise, you could say that a subject (by definition) is something of which something else is said (and that something else, by definition, is called a predicate).
“An animal” can be said of “a dog.” And likewise, “a dog” is something of which “an animal” is said. “Blue” can be said of “the sky.” Likewise, “the sky” is something of which “blue” is said.
“A dog” and “the sky” in these cases are subjects because they are things “that of which the other things are said” and are not things (in this case) that are “not themselves in turn said of any other thing” because a subject, by definition, is “that of which the other things are said, but which is not itself in turn said of any other thing.”
That might be really confusing. And I hope I didn’t have any glaring mistakes here. I admit, I was a bit overwhelmed with the confusing language. But I hope that helps. I hope your analysis goes well.
