FORM

[A20/B34] Form is defined as "that which so determines the manifold of appearance that it allows of being ordered in certain relations"; it is thus opposed to matter and content. In the Aesthetic Kant argues that "form must lie ready for the sensations a priori in the mind"; this is crucial to his thesis that space and time, as forms of intuition, are transcendentally ideal. He also speaks of forms of logic.
