Single Idea 8451

[from 'Critique of Pure Reason' by Immanuel Kant, in 28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique ]

Full Idea

For Kant, existence derives from a true affirmative subject-copula-predicate judgement; existence is not a real predicate, but is merely derivatively implied by the copula ('is').

Gist of Idea

Existence is merely derived from the word 'is' (rather than being a predicate)

A Reaction

This is Kant's understanding of 'existence is not a predicate', prior to the later move of Brentano and Frege, which places existence claims in the quantifier, which is outside the proposition.
