What is remarkable is how popular this heretic remains nearly three and a half centuries after his death, and not just among scholars. Spinoza's contemporaries, René Descartes and Gottfried Leibniz, made enormously important and influential contributions to the rise of modern philosophy and science, but you won’t find many committed Cartesians or Leibnizians around today. The Spinozists, however, walk among us. They are non-academic devotees who form Spinoza societies and study groups, who gather to read him in public libraries and in synagogues and Jewish community centres. Hundreds of people, of various political and religious persuasions, will turn out for a day of lectures on Spinoza, whether or not they have ever read him. There have been novels, poems, sculptures, paintings, even plays and operas devoted to Spinoza.

...Now Spinoza, my master and model in respect to the first point [the natural basis of morality], does not satisfy me on the second [the humane possibilities, the "types of excellence towards which life may be directed"]; and I will take this opportunity, since I may not have any other, of clearing my conscience of ambiguity in that respect. The complete moralist must not only be sound in physics, but must be inwardly inspired by a normal human soul and an adequate human tradition; he must be a complete humanist in a complete naturalist. Spinoza was not only a complete naturalist but, by a rare combination, also a spiritual man, seeing and accepting the place of the human heart in the universe; accepting it not grudgingly or viciously or frivolously, as your worldling does, but humbly and joyously: humbly in that he asked to be nothing more than he was, and joyously because what he was allowed him, in spirit, to salute and to worship every form of the good. Nevertheless, Spinoza was not a complete humanist. He had no idea of human greatness and no sympathy with human sorrow. His notion of the soul was too plebeian and too quietistic. He was a Jew not of Exodus or Kings but of Amsterdam. He was too Dutch, too much the merchant and artisan, with nothing of the soldier, the poet, the prince, or the lover. [...] He was virtuous but not normal. [...] He was a genius; but as a guide in the spiritual life, he was narrow and inadequate.

The rediscovery of Spinoza by the Germans contributed to the shaping of the cultural destinies of the German people for almost two hundred years. Just as at the time of the Reformation no other spiritual force was as potent in German life as the Bible, so during the eighteenth and nineteenth centuries no other intellectual force so dominated German life as Spinozism. Spinoza became the magnet to German steel. Except for Immanuel Kant and Herbart, Spinoza attracted every great intellectual figure in Germany during the last two centuries, from the greatest, Goethe, to the purest, Lessing.
