Hugo Grotius

"Liberty is the power that we have over ourselves."

"Even God cannot make two times two not make four."

"Not to know certain things is a great part of wisdom."

"So is there no kind of life more wicked than that of mercenary Souldiers, who without any respect had to the equity of the Cause, fight only for plunder and pay."

"The ideal of reason that had emerged in the modern world with Grotius and Descartes found one of its first typical expressions in Spinoza."
