Abstract

ON SPINOZA’S PROOFS OF (SPINOZIAN) GOD’S EXISTENCE AND THE PROOF OF THE UNIQUENESS OF THE SPINOZIAN SUBSTANCE In this paper I analyze Spinozian ontological arguments for God’s existence from Ethica ordine geometrico demonstrata. I argue that the first proof suffers from circulus vitiosus, whereas the others have at least one non-obvious premise. I also consider P. Gut’s modification of the first proof, reported to me during the conference “The Philosophy of the 17th Century—Its Origins and Continuations” (Gdańsk, 16.06.2011). Meanwhile, I address D. Chlastawa’s remark that theorem 7 and 14 from Ethica… makes Spinoza’s theory inconsistent. Keywords: SPINOZA, GOD’S EXISTENCE, PROOF, UNIQUENESS, SUBSTANCE Discipline: PHILOSOPHY
