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.

Kant is erroneously viewed as the founder of German philosophy, and an ingenious poet-philosopher, Heinrich Heine, has even drawn a parallel between the different phases of the French Revolution and those of German philosophy, putting next to each other as analogous phenomena Kant and Robespierre, Fichte and Napoleon, Schelling and the Restoration, Hegel and the July Revolution. But the true founder of German philosophy - if one wishes to name a personal representative for the spirit of the age [Zeitgeist] - is none other than [the thinker] whose world view lies equally at the foundation of French social philosophy - Spinoza; and as far as Heine's analogy goes, it is only Kant and Robespierre, i.e. the religious revolution, who are analogous phenomena.
