Ethics, Demonstrated in Geometrical Order
1661 AD - 1675 AD
AKA Ethica, ordine geometrico demonstrata
Spinoza's magnum opus which opposes Descartes' philosophy of mind–body dualism and earned Spinoza recognition as one of Western philosophy's most important thinkers.
The book is perhaps the most ambitious attempt to apply the method of Euclid in philosophy. Spinoza puts forward a small number of definitions and axioms from which he attempts to derive hundreds of propositions and corollaries, such as
- "When the Mind imagines its own lack of power, it is saddened by it"
- "A free man thinks of nothing less than of death"
- "The human Mind cannot be absolutely destroyed with the Body, but something of it remains which is eternal."
Hegel said, "The fact is that Spinoza is made a testing-point in modern philosophy, so that it may really be said: You are either a Spinozist or not a philosopher at all." His philosophical accomplishments and moral character prompted Gilles Deleuze to name him "the 'prince' of philosophers".
