You compare Cardozo with Spinoza; but as far as I can judge by your book there is no intellectual comparison. Spinoza was not soft. I have been all m… - Benedictus de Spinoza

The (respective) position of Judaism toward Spinoza coincides with the (respective) position of Europe toward him. However, it does not completely coincide with it. Spinoza played a special role in the Judaism of the past century. When what mattered was the justification of the breakup of the Jewish tradition and the entry of the Jews into modern Europe, perhaps no better, but certainly no more convenient, reference offered itself than the appeal to Spinoza. Who was more suitable for undertaking the justification of modern Judaism before the tribunal of the Jewish tradition, on the one hand, and before the tribunal of modern Europe, on the other, than Spinoza, who, as was almost universally recognized, was a classical exponent of this Europe and who, as one did not grow weary of at least asserting, had thought his thoughts in the spirit of Judaism and by means of Judaism? It is clear that, at a time when modern Europe has been shaken to its foundations, one can no longer justify oneself before this Europe for the sake of Judaism, nor before Judaism for the sake of this Europe, supposing one still wants to do so.

He was in a certain sense the first Zionist of the last three hundred years, [...] Through keen insight into Jewish and world history he prophesied the rebirth of the State of Israel.

Of all the great modern philosophers, Spinoza is probably the most interesting in relation to human life, and is certainly the most lovable and high-minded. Unfortunately, the difficulty and crabbedness of his writing make it very hard for people who are not serious students of philosophy to understand even what is not inherently difficult in his doctrines. He therefore requires commentaries to translate him into easier language, if his main ideas are to be appreciated as widely as possible. [...] Spinoza's philosophy, however, whether we agree with it or not, remains one of the noblest monuments of human genius, and whoever makes it more widely accessible is doing a useful work. To readers unacquainted with philosophy, Mr. Picton's book may therefore be confidently recommended.
