I am reading Martin Heidegger's Discourse on Thinking. At the beginning of "Conversation on a Country Path About Thinking*, the Scholar remarks: (page 58-9)
But thinking, understood in the traditional way, as re-presenting is a kind of willing. Kant, too, understands thinking this way when he characterizes it as spontaneity. To think is to will, and to will is to think.
The Teacher in this conversation doesn't agree that thinking is willing. In order to understand this better, I want to read what Kant has to say about thinking, willing, spontaneity and re-presenting.
Where can I find that in Kant's writings?
