that the worshipper was born a Jew and not a heathen, a free man and not a slave, a man and not a woman. Such an historical investigation would have spared Kant an unfortunate necessity in which he now becomes involved, in that he makes these three conceptions spring necessarily from the nature of reason, and yet explains that they are untenable and unverifiable by the reason, and thus makes the reason itself a sophisticator; for he says, p. 339; V. 397: "There are sophistications, not of man, but of pure reason itself, from which even the wisest cannot free himself, and although after much trouble he may be able to avoid error, yet he never can escape from the illusion which unceasingly torments and mocks him." Therefore these Kantian "Ideas of the Reason" might be compared to the focus in which the converging reflected rays from a concave mirror meet several inches before its surface, in consequence of which, by an inevitable process of the understanding, an object presents itself to us there which is a thing without reality.
But the name "Idea" is very unfortunately chosen for these pretended necessary productions of the pure theoretical reason, and violently appropriated from Plato, who used it to denote the eternal forms which, multiplied through space and time, become partially visible in the innumerable individual fleeting things. Plato's "Ideas" are accordingly throughout perceptible, as indeed the word which he chose so definitely signifies, for it could only be adequately translated by means of perceptible or visible things; and Kant has appropriated it to denote that which lies so far from all possibility of perception that even abstract thought can only half attain to it. The word "Idea," which Plato first introduced, has, more over, since then, through two-and-twenty centuries, always retained the significance in which he used it; for not only all ancient philosophers, but also all the Scholastics, and indeed the Church Fathers and the theologians of the Middle Ages, used it only in that Platonic sense, the
