D. The idea of a thing that is not dependent on anything else | ||
The term 'substance' is used to mean different things, meanings that are arguably linked in various ways. Descartes works with the conception expressed in D.
Descartes also postulated a single corporeal substance out of which everything material was made, which is C. (if you think of the universe as material).
Locke seems to argue that the complex idea of a thing (eg a table) is made up of set of ideas of its properties PLUS the concept of 'substance', which is B.
Which leaves the badger. But you could interpret the question to mean Is 'badger' the concept of a substance rather than say the concept of a property. If you did so you would have to conclude that all four possible answers are substance concepts and the question has the answer: None.
