W kwestii dowodów na istnienie Boga i dowodu na jedyność Spinozjańskiej substancji

Abstract 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.
