Of all heroes , Spinoza was Einstein 's greatest. No one expressed more strongly then he a belief in the harmony , the beauty , and most of all the ultimate comprehensibility of nature.
The great Jewish scientists and philosophers of the last few generations - Spinoza, Einstein, Freud, Robert Oppenheimer and others - were natives of Europe and America.
The religious geniuses of all ages have been distinguished by this kind of religious feeling, which knows no dogma and no God conceived in man's image; so that there can be no church whose central teachings are based on it. Hence it is precisely among the heretics of every age that we find men who were filled with this highest kind of religious feeling and were in many cases regarded by their contemporaries as atheists, sometimes also as saints. Looked at in this light, men like Democritus, Francis of Assisi, and Spinoza are closely akin to one another.
There's a sense in which Marx does contribute to the fund of human knowledge, and we can no more dismiss him than we can [George] Hegel or [Jean-Jacques] Rousseau or [Baruch] Spinoza or [Charles] Darwin; you don't have to be a Darwinian to appreciate Darwin's views, and I don't have to be a Marxist to appreciate what is valid in a number of [Karl] Marx's writings-and Marx would call that a form of simple commodity production rather than capitalism.
[Malebranche] teaches that we see all things in God himself. This is certainly equivalent to explaining something unknown by something even more unknown. Moreover, according to him, we see not only all things in God, but God is also the sole activity therein, so that physical causes are so only apparently; they are merely occasional causes. ( Recherches de la vérité , Livre VI, seconde partie, chap. 3. ) And so here we have essentially the pantheism of Spinoza who appears to have learned more from Malebranche than from Descartes.
When Maimonides says that the Messiah will come but that 'he may tarry,' we see the origin of every Jewish shrug from Spinoza to Woody Allen.
