Baruch Spinoza Quotes
Freedom is absolutely necessary for the progress in science and the liberal arts.
Spinoza, Baruch. Tractatus Theologico-Politicus. Translated by R. H. M. Elwes, George Bell and Sons, 1883, p. 257, Ch. 20.
The societies that had regularly produced the great advances in the sciences were those that allowed its citizens much liberty—liberty of thought, expression, association, etc. Where religious dogma controlled thought and expression, great scientific achievements were far less probable or less productive. Imagine, what Galileo might have achieved if the Church had not curtailed his efforts. When Islamic society was open, the sciences flourished whereas they were stifled in Christian Europe, but once Islam closed and liberty was no more, Islamic science degenerated to its low point of the 21st century.
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.
