I do not know how to teach philosophy without becoming a disturber of the peace. - Benedictus de Spinoza

The great Voltaire once accused Spinoza of ‘abusing metaphysics’. Is not the uncompromising nature of metaphysics more important today than ever? Has not liberated thinking become the most valued freedom at a time when political systems, social constraints, moral codes and political correctness often control our thinking?

[Spinoza, the Romantic] The paradox marking Spinoza's reappearance in modernity is well known. If Mendelssohn wished to “give him new credence by bringing him closer to the philosophical orthodoxy of Leibniz and Wolff,” and Jacobi, “by presenting him as a heterodox figure in the literal sense of the term, wanted to do away with him definitively for modern Christianity”—well, “both failed in their goal, and it was the heterodox Spinoza who was rehabilitated.” The Mendelssohn-Jacobi debate can be grafted onto the crisis of a specific philosophical model. It generates a figure of Spinoza capable of assuaging the exacerbated spiritual ten­sion of that epoch, and of constituting the systematic preamble of the relation between power and substance—between subject and nature. Spinoza, the damned Spinoza, had a resurgence in modernity as a Romantic philosopher. Lessing won out by recognizing in Spinoza an idea of nature which was capable of balancing the relation between feeling and intellect, freedom and necessity, and history and reason. Herder and Goethe, against the subjective and revolutionary impa­tience of the Sturm und Drang, based themselves on this powerful image of synthesis and recomposed objectivity: Spinoza is not only the figure of Romanticism; he constitutes its grounding and its fulfillment.

When Plato writes his dialogues or his didactic works, he takes great care to differentiate them from any other literary, rhetorical or sophistic discourse. When Descartes or Spinoza writes, no one can mistake it for 'literature'. When Kant or Hegel writes, we are not dealing with a moral exhortation, a religious sermon, or a novel.
