It is not possible, I think, to rise from the perusal of the arguments of Clark and Spinoza without a deep conviction of the futility of all endeavor… - Benedictus de Spinoza

Las traslúcidas manos del judío Labran en la penumbra los cristales Y la tarde que muere es miedo y frío. (Las tardes a las tardes son iguales.) Las manos y el espacio de jacinto Que palidece en el confín del Ghetto Casi no existen para el hombre quieto Que está soñando un claro laberinto. No lo turba la fama, ese reflejo De sueños en el sueño de otro espejo, Ni el temeroso amor de las doncellas. Libre de la metáfora y del mito abra un arduo cristal: el infinito Mapa de Aquél que es todas Sus estrellas. (Here in the twilight the translucent hands Of the Jew polishing the crystal glass. The dying afternoon is cold with bands Of fear. Each day the afternoons all pass The same. The hands and space of hyacinth Paling in the confines of the ghetto walls Barely exists for the quiet man who stalls There, dreaming up a brilliant labyrinth. Fame doesn't trouble him (that reflection of Dreams in the dream of another mirror), nor love, The timid love women. Gone the bars, He's free, from metaphor and myth, to sit Polishing a stubborn lens: the infinite Map of the One who now is all His stars.) [Translated from the Spanish by Willis Barnstone]

Spinoza did not envision secular Judaism. To be a secular or assimilated Jew is, in his view, nonsense. It is to be a nonsectarian sectarian. For him, Judaism without an observance of its textually and historically defined tenets, laws, and ceremonies would be a masquerade. [...] Of course, Spinoza had great contempt for traditional sectarian religions, and Judaism in particular. And he did argue that Jewish law is no longer binding on contemporary Jews. Perhaps in this sense he unwittingly opened the door for a secular or even Reform Judaism. But he also had a very strict understanding of what was to count as Judaism. Spinoza may have been a religious reformer, but what he envisioned was not reform within Judaism. Rather, what he had in mind was a universal rational religion that eschewed meaningless, superstitious rituals and focused instead on a few simple moral principles, above all, to love one's neighbor as oneself.

If he [Friedrich Wilhelm Schelling] had consulted me as an old friend in this matter, I would have answered: haven't you learned that much from our old master Benedict Spinoza that we and people like us can only thrive in private life? Even if the Elector of the Palatine had guaranteed this intelligent Jew total freedom to teach his convictions, the author of the Tractatus Theologico-Politicus would have answered: Honorable majesty, you cannot do that because freedom to teach, directed against the established powers, can only lead to the following: either I would overthrow the sanctioned order of things or I would be driven out in shame and disgrace. [Original in German: Hätte er mich, als alter Freund, in diesem Falle gefragt, ich würde geantwortet haben: hast du von unserm alten Herrn und Meister Benedict Spinoza nicht soviel gelernt, daß wir unseres Gleichen blos in Stillen gedeihen? Hätte der Kurfürst von der Platz diesem klugen Juden auch völlige Lehrfreiheit in Heidelberg zugesagt, so hätte der Verfasser des Tractatus theologico-politicus geantwortet: Ew. Durchlaucht, das können Sie nicht, denn Lehrfreiheit gegen das Bestehende kann nur dazu führen, daß ich entweder ihren sanctionirten Zustand umwerfe, oder daß ich daraus mit Schimpf und Schande vertrieben werde.]
