Spinoza, then, emerged as the supreme philosophical bogeyman of Early Enlightenment Europe. Admittedly, historians have rarely emphasized this. It ha… - Benedictus de Spinoza

The Declaration of Independence, that extraordinary document first drafted by Thomas Jefferson, softly echoes Spinoza. John Locke, Spinoza's contemporary — both were born in 1632 — is a more obvious influence on Jefferson than Spinoza was. But Locke had himself been influenced by Spinoza's ideas on tolerance, freedom and democracy. In fact, Locke spent five formative years in Amsterdam, in exile because of the political troubles of his patron, the Earl of Shaftesbury. Though Spinoza was already dead, Locke met in Amsterdam men who almost certainly spoke of Spinoza. Locke's library not only included all of Spinoza's important works, but also works in which Spinoza had been discussed and condemned. It's worth noting that Locke emerged from his years in Amsterdam a far more egalitarian thinker, having decisively moved in the direction of Spinoza. He now accepted, as he had not before, the fundamental egalitarian claim that the legitimacy of the state's power derives from the consent of the governed, a phrase that would prominently find its way into the Declaration. Locke's claims on behalf of reason did not go as far as Spinoza's. He was firm in defending Christianity's revelation as the one true religion against Spinoza's universalism. In some of the fundamental ways in which Spinoza and Locke differed, Jefferson's view was more allied with Spinoza. (Spinoza's collected works were also in Jefferson's library, so Spinoza's impact may not just have been by way of Locke.)

El alma humana, cuantas veces percibe las cosas según el orden común de la naturaleza, no tiene conocimiento adecuado ni de sí misma, ni de su cuerpo, ni de los cuerpos exteriores, sino tan solo un conocimiento confuso y mutilado

Because of the specific epistemological interests of English philosophy and the dominance of Cartesianism in French thought, Spinoza's philosophical influence was centered in Germany. Of the great German figures Gotthold Ephraim Lessing was the first to come under the spell of Spinoza. He was a man of broad vision, with a hundred cultural interests and a critical disposition of mind, and would not accept any philosophical system in its totality. While he did not accept Spinozism in its entirety, he subscribed to its pantheistic doctrines. But more than he admired Spinoza's philosophy, he was attracted to him by his great earnestness of purpose, his strength of character, and his moral courage.
