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.

...The materialist is primarily an observer; and he will probably be such in ethics also; that is, he will have no ethics, except the emotion produced upon him by the march of the world. If he is an esprit fort and really disinterested, he will love life; as we all love perfect vitality, or what strikes us as such, in gulls and porpoises. This, I think, is the ethical sentiment psychologically consonant with a vigorous materialism: sympathy with the movement of things, interest in the rising wave, delight at the foam it bursts into, before it sinks again. Nature does not distinguish the better from the worse, but the lover of nature does. He calls better what, being analogous to his own life, enhances his vitality and probably possesses some vitality of its own. This is the ethical feeling of Spinoza, the greatest of modern naturalists in philosophy; and we shall see how Lucretius, in spite of his fidelity to the ascetic Epicurus, is carried by his poetic ecstasy in the same direction.

These old philosophers were heartless; philosophizing was always a kind of vampirism. Looking at these figures, even Spinoza, don't you have a sense of something profoundly enigmatic and uncanny? [...] I mean categories, formulas, words (for, forgive me, what was left of Spinoza, amor intellectualis dei, is mere clatter and no more than that: What is amor, what is deus, if there is not a drop of blood in them?)
