Existence Quote by Immanuel Kant
““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.””
