Immanuel Kant (1724 — 1804)

The outstanding philosopher of the enlightenment. We have seen ideas as above the phenomena, as in the phenomena and now as separate from the phenomena. Kant’s task was to examine how we come to understand the world or rather how the world can be known by us. Having mapped out what is knowable, this world of appearances, he maintained there is an unknowable world of things-in-themselves.
