This relates to a previous question as to whether or not we are "born with" Kantian categories.
I had objected that this would imply that the categories in some manner depend upon or inhere in a physical process, while they are logically prior to any such physical process. I am not sure I'm correct about this or what sorts of interpretations Kant's categories might allow.
First, are there problems in thinking of the categories as "innate abilities" in the manner of instincts, neural constructs, language, or Chomskey's deep grammar? Do such interpretations contradict Kant's meaning and essential elements of his theory?
Second, how is the whole process of physical gestation and birth to be understood in terms of Kantian idealism? Does Kant anywhere discuss this? Do idealists generally discuss this developmental aspect of mind-body problems?
