Johann Wolfgang von Goethe, in his diary of 1812 - Benedictus de Spinoza

How would it be possible, if salvation were ready to our hand, and could without great labor be found, that it should be by almost all men neglected? But all things excellent are as difficult as they are rare.

...[T]he once-accepted assumption that Spinoza was considered a “dead dog” in Kant's day [i.e. before the break of the Pantheismusstreit] is no longer tenable. [...] Suffice it here to recall the well-known fact that Spinoza is the subject of the single longest entry in Bayle's Dictionnaire (1702). It is true that Bayle attempts to refute Spinoza (though some have doubted the sincerity of his intentions) but unlikely that so much space would be dedicated to refuting a neglected philosopher—unlikely, indeed, that Spinoza's relevance would wane once this high-profile entry had been published about him. J. Zedler's Grosses Universal Lexikon (1731–54) gives a similar impression, devoting to Spinoza a five-page discussion. Descartes, by comparison, is discussed in one page. Hume, Locke, Hobbes, and Plato are equally dealt with in one page (or less) each. D. Diderot and J. d'Alembert's Encyclopédie (1751–72) similarly dedicates to Spinoza five times more space than to most relevant thinkers in the history of philosophy. While speaking of Spinoza's metaphysics in extremely hostile terms, the Encyclopédie gives a reliable account of the Ethics definitions and axioms and discusses at length its most important demonstrations, especially E1p1–11. The Dictionnaire, the Lexikon, and the Encyclopédie were the main transmitters of Enlightenment thought. The attention they devoted to Spinoza ensured him a place at the heart of Enlightenment debate. It would be impossible for any educated reader to avoid contact with Spinoza's ideas. It would be easy for every metaphysician to get a grasp on the system of the Ethics. And it would be tempting, for every philosophically inclined thinker, to read Spinoza for themselves.

Neutrality toward Spinoza set in once one was able to admit that the "modern worldview," whose victory was decisively aided by Spinoza's metaphysics, does not, or does not entirely, coincide with this metaphysics. But even at this stage it was still generally maintained, and even emphasized, that among the three great Western philosophers of the seventeenth century — Descartes, Hobbes, and Spinoza — Spinoza was the most important one because, he was the most progressive one. He alone had drawn certain consequences from the foundations of modern philosophy, which became fully clarified only in the nineteenth century and which henceforth determined the general consciousness.
