Baruch Spinoza, 23 years old of the Jewish community for heresy, decides to devote his life to philosophy. His objective? To discover a real good that would "provide him for eternity the enjoyment of supreme and incessant joy." During the twenty years remaining to live, Spinoza builds a revolutionary work. How could this man, in the middle of the seventeenth century, be the forerunner of the Enlightenment and our modern democracies? The pioneer of a historical and critical reading of the Bible? The founder of the psychology of the depths? The initiator of philology, sociology, and ethology? And above all, the inventor of a philosophy based on desire and joy, which upsets our conception of God, morality and happiness? In many respects, Spinoza is not only well ahead of his time, but also of ours. This is what I call the "miracle" Spinoza.F. L.
