Baruch Spinoza
"Sane sicut lux se ipsam et tenebras manifestat, sic veritas norma sui et falsi est."
From the light and dark things happen, you can see their roots of true and false.
"In the Ethics, "Spinoza wrote the last indisputable Latin masterpiece, and one in which the refined conceptions of medieval philosophy are finally turned against themselves and destroyed entirely."[11] Hegel said, "You are either a Spinozist or not a philosopher at all."[12] His philosophical accomplishments and moral character prompted 20th-century philosopher Gilles Deleuze to name him "the 'prince' of philosophers".[13]" -wikipedia entry 141217
