Kant Idealism Quotes & Sayings

For if we regard space and time as properties that must, as regards their possibility, be found in things in themselves, [ ... ] then we really cannot blame the good Bishop Berkeley for degrading bodies to mere illusion. Nay, even our own existence, which would thus be made dependent on the self-subsistent reality of a non-entity such as time, would, along with this time, be changed into mere illusion - an absurdity of which hitherto no one has been guilty. — Immanuel Kant

[...] As soon as the universe is reduced to the laws of mind, man, now become creator, has no longer any means of rising above himself. Legislator of a world to which his own mind has given birth, he is henceforth the prisoner of his own work, and he will never escape from it anymore.
