Banished from the Jewish community at 23 for heresy, Baruch Spinoza decides to devote his life to philosophy. His goal? To discover a real good which would "procure for eternity the enjoyment of a supreme and incessant joy. During the twenty years remaining to live, Spinoza is building 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 ways, Spinoza is not only far ahead of his time, but also on ours. This is what I call the "miracle" Spinoza.
