Spinoza
Baruch Spinoza, often Benedictus de Spinoza, was a Dutch philosopher. The breadth and importance of Spinoza's work was not fully realized until many years after his death. By laying the groundwork for the 18th-century Enlightenment and modern biblical criticism, including modern conceptions of the self and, arguably, the universe, he came to be considered one of the great rationalists of 17th-century philosophy.
His magnum opus, the posthumous Ethics, in which he opposed Descartes' mind–body dualism, has earned him recognition as one of Western philosophy's most important thinkers. 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."
Philosopher Georg Wilhelm Friedrich Hegel said of all contemporary philosophers, "You are either a Spinozist or not a philosopher at all."
“He who wishes to revenge injuries by reciprocal hatred will live in misery. But he who endeavors to drive away hatred by means of love, fights with pleasure and confidence; he resists equally one or many men, and scarcely needs at all the help of fortune. Those whom he conquers yield joyfully”
“it is certain that seditions, wars, and contempt or breach of the laws are not so much to be imputed to the wickedness of the subjects, as to the bad state of the dominion.”
“Those who know the true use of money, and regulate the measure of wealth according to their needs, live contented with few things.”
“In proportion as we endeavor to live according to the guidance of reason, shall we strive as much as possible to depend less on hope, to liberate ourselves from fear, to rule fortune, and to direct our actions by the sure counsels of reason.”
“The more clearly you understand yourself and your emotions, the more you become a lover of what is.”
“Further conceive, I beg, that a stone, while continuing in motion, should be capable of thinking and knowing, that it is endeavoring, as far as it can, to continue to move. Such a stone, being conscious merely of its own endeavor and not at all indifferent, would believe itself to be completely free, and would think that it continued in motion solely because of its own wish. This is that human freedom, which all boast that they possess, and which consists solely in the fact, that men are conscious of their own desire, but are ignorant of the causes whereby that desire has been determined.”
“No matter how thin you slice it, there will always be two sides.”
“The more you struggle to live, the less you live. Give up the notion that you must be sure of what you are doing. Instead, surrender to what is real within you, for that alone is sure....you are above everything distressing.”
