Benedict Spinoza is one of the greatest rationalist philosophers. His writings constitute an era in the history of European thought, and their study became a necessary moment of all training courses in metaphysics. A characteristic feature of Spinoza's treatises is a strict sequence of thought and a clear organization of the text. Spinoza's ideas, especially his central work, Ethics, had a powerful impact on the culture of the 17th-19th centuries: Spinoza was loved, read, interpreted, not only philosophers such as Berkeley, Hume, Schelling, Hegel argued with him, but also great scientists, enlighteners, poets - Diderot, Gereder, Goethe. In the work "Ethics," the Dutch philosopher Benedict Spinoza (1632-1677) outlined his views about God, the world, the man in it, about the human essence, soul, feelings and mind. According to Spinoza, the world is a natural system that can be known geometrically.
