strictly from fundamental principles of Spinoza's abstract, dialectical psychology; but its truth or its practical applicability is because of that not in the least impaired. Indeed, because of its dialectical form its range of meaning is greatly increased. Spinoza's dictum applies to what William James called the "psychologist's fallacy." It also applies to what John Ruskin called the "pathetic fallacy." Again, it applies to the fallacy Franz Boas exposed and which he may justly have called the "anthropologist's fallacy." And it applies also to what one may, with a great deal of benefit, dub the "ethicist's fallacy." For the very same constitutional weakness of man to identify confusedly his own nature with that of the object he is contemplating or studying, is most flagrantly and painfully evident in the fields of theoretical and practical ethics. The "ethicist's fallacy" is the source of all absolutism in theory, and all intolerance in practice.

All four fallacies just enumerated come under Spinoza's dictum as special cases come under a general law. And these four are by no means the only instances of the common habit of mind. From no field of human endeavor is the mischief-working fallacy ever absent. We find it lodged in the judge's decision, the propagandist's program, the historian's record, the philosopher's system. In the field of metaphysical poetry it has recently been identified by Santayana as "normal madness." In its milder forms, the fallacy is now known by every one as the "personal equation"; in its pronounced, abnormal manifestations it is known by the psychoanalysts as "transference." It is a Protean fallacy woven into the emotional texture of the human mind. Nothing, for it, is sacred enough to be inviolate. For Spinoza discovered it sanctimoniously enshrined even in the Sacred Scriptures. As he brilliantly shows us in the Tractatus Theologico-Politicus, the prophets' ideas about God tell us more about the prophets than about God.

The far-reaching significance of Spinoza's propositions is one of their most remarkable characteristics. This is due to the fact, contemporary philological philosophers notwithstanding, that Spinoza defined the essence, the generating principle, not the accidental qualities, of the human mind.

Another example may not be out of place. Spinoza's proposition that anything may be accidentally (in the philosophic sense of "accident") a cause of pleasure, pain, or desire seems to explain the essence of all the particular variations of the psychological phenomena known now by all who have been aroused to the significance of their vagrant cryptic slumbers, as the phenomena of symbolism, sublimation, and fetich worship. Spinoza's proposition explains all the phenomena adequately because among the fundamental human emotions, Spinoza like Freud—if we discount the recent attempt to go beyond the pleasure-principle—reckons only three: desire, pleasure and pain. And with Spinoza, as with the Freudians, it sometimes seems that desire is more fundamental than the other two, for desire expresses, in Spinoza's terminology, the essence of man. Desire however may be stimulated by almost anything. It requires the least sanity of mind, therefore, to prevent one from scandalously over-emphasizing one particular class of objects—of desire.
