I have laboured carefully, not to mock, lament, or execrate, but to understand human actions. - Benedictus de Spinoza

En la reminiscencia, en efecto, el alma tiene el pensamiento de esta sensación, pero no en la continuidad de su duración. Así, la idea de la sensación no es la duración misma de la sensación, es decir, ella no es propiamente su memoria. En cuanto a saber si las ideas mismas están sujetas a alguna corrupción, lo veremos en la Filosofía.

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.

I find no evidence that Jefferson read Spinoza, although his library does contain a copy of his works. Enlightenment thought is so saturated with Spinoza's ideas, however, that they could have reached Jefferson by innumerable routes.
