3 ideas

7. Existence / E. Categories / 1. Categories
Categories are general concepts of objects, which determine the way in which they are experienced [Kant]
     Full Idea: The categories are the concepts of an object in general, by means of which its intuition is regarded as determined with regard to one of the logical functions of government.
     From: Immanuel Kant (Critique of Pure Reason [1781], B128/A95)
     A reaction: These are Kant's 'transcendental' categories. I'm wondering what he made of our more normal categories, such as animal species, genera etc.
Categories are necessary, so can't be implanted in us to agree with natural laws [Kant]
     Full Idea: If one proposed a middle way, that categories are subjective predispositions for thinking, implanted in us so that their use would agree exactly with the laws of nature,..then the categories would lack the necessity which is essential to their concept.
     From: Immanuel Kant (Critique of Pure Reason [1781], B167)
     A reaction: Kant might want to rethink this once he got the hang of the theory of evolution. If we have innate categories, they must have some survival value. I don't understand Kant's claim that the categories are necessary. They just reflect nature.
7. Existence / E. Categories / 2. Categorisation
Does Kant say the mind imposes categories, or that it restricts us to them? [Rowlands on Kant]
     Full Idea: It is unclear whether Kant says the mind imposes space and time and categories, such as substance and cause and effect, on empirical objects, or whether our mind restricts our cognition to such features of noumenal objects. Imposition, say the majority.
     From: comment on Immanuel Kant (Critique of Pure Reason [1781]) by Mark Rowlands - Externalism Ch.3
     A reaction: Rowlands says, rightly, that Kant probably thought the mind imposed categories, but that he should have said that it restricts us to them. The imposition view leads to idealism, anti-realism and madness; restriction is common sense, really.
