...Kant is Spinoza's only adversary in the realm of occidental culture. Constantin Bruner has aptly stated that everyone must be either a Spinozist or a Kantian. The modern intellectual world, however, is overwhelmingly Spinozistic. Kant created only a school of thought, but Spinoza gave birth to a new culture and religion. Kant was long forgotten in his own fatherland until he was revived by Hermann Cohen. Spinoza has always lived in the centers of modern culture. Although at first he was maligned, calumniated, and even damned, he came to be later blessed and admired. He was always a subject of discussion in religious, philosophical, and scientific circles, because he dangled before man's eye the picture of a world without contradictions or abuses. Kant has accomplished only a special task. He examined and described the mechanism of the human mind rather than the mechanism of the world. He can be compared to Aristotle, as Spinoza can be likened to Plato. Kant is the very embodiment of idealism, while Spinoza is the representative of extreme naturalism.

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 my life long a fervent disciple of Spinoza precisely on account of his firmness, of his uncompromising naturalism. Yet even he leaves out the three traditions which, however false their cosmology, seem to me morally sound: the Greek, the Catholic, and the Indian. I am therefore not a disciple of Spinoza in his ideal of human life: It leaves out poetry, art, traditional religion, military and constructive patriotism. His society would be a tame society, where there would be no masters, but all would be voluntary slaves. Perhaps you feel something of my difficulty when you point out that "art" is an indispensable ingredient in everything human.
