Baruch Spinoza Quotes
But if men would give heed to the nature of substance they would doubt less concerning the Proposition that Existence appertains to the nature of substance: rather they would reckon it an axiom above all others, and hold it among common opinions. For then by substance they would understand that which is in itself, and through itself is conceived, or rather that whose knowledge does not depend on the knowledge of any other thing.

Baruch (de) Spinoza was a Dutch philosopher of Portuguese Sephardi origin. One of the early thinkers of the Enlightenment and modern biblical criticism, including modern conceptions of the self and the universe, he came to be considered one of the great rationalists of 17th-century philosophy. Inspired by the groundbreaking ideas of René Descartes, Spinoza became a leading philosophical figure of the Dutch Golden Age. Spinoza's given name, which means "Blessed", varies among different languages. In the Netherlands he used the Portuguese name Bento. In his Latin and Dutch works, he used Latin: Benedictus de Spinoza.
