Immanuel Kant

Notes

Immanuel Kant (1724–1804), German philosopher. Argued that we know the world only as it appears through the structures of our minds, that morality rests on duty and the categorical imperative rather than consequences, and that existence is not a predicate, which sinks the Ontological Argument. The source of Deontology and of a great deal of homework.

Ontological Argument

Existence is simply asserted to be "greater" than non-existence, without justification. Immanuel Kant's objection (Critique of Pure Reason, 1781) stands: existence is not a predicate. Saying that a thing exists adds nothing to the concept…
