But here an important distinction presents itself. Philosophy is employed on objects of the inner SENSE, and cannot, like geometry, appropriate to every construction a correspondent outward intuition. Nevertheless, philosophy, if it is to arrive at evidence, must proceed from the most original construction, and the question then is, what is the most original construction or first productive act for the inner sense. The answer to this question depends on the direction which is given to the inner sense. But in philosophy the inner sense cannot have its direction determined by an outward object. To the original construction of the line I can be compelled by a line drawn before me on the slate or on sand. The stroke thus drawn is indeed not the line itself, but only the image or picture of the line. It is not from it, that we first learn to know the line; but, on the contrary, we bring this stroke to the original line generated by the act of the imagination; otherwise we could not define it as without breadth or thickness. Still however this stroke is the sensuous image of the original or ideal line, and an efficient mean to excite every imagination to the intuition of it. It is demanded then, whether there be found any means in philosophy to determine the direction of the inner sense, as in mathematics it is determinable by its specific image or outward picture. Now the inner sense has its direction determined for the greater part only by an act of freedom. One man’s consciousness extends only to the pleasant or unpleasant sensations caused in him by external impressions; another enlarges his inner sense to a consciousness of forms and quantity; a third in addition to the image is conscious of the conception or notion of the thing; a fourth attains to a notion of his notions--he reflects on his own reflections; and thus we may say without impropriety, that the one possesses more or less inner sense, than the other. This more or less betrays already, that philosophy in its first principles must have a practical or moral, as well as a theoretical or speculative side. This difference in degree does not exist in the mathematics. Socrates in Plato shows, that an ignorant slave may be brought to understand and of himself to solve the most difficult geometrical problem. Socrates drew the figures for the slave in the sand. The disciples of the critical philosophy could likewise (as was indeed actually done by La Forge and some other followers of Des Cartes) represent the origin of our representations in copper-plates; but no one has yet attempted it, and it would be utterly useless. To an Esquimaux or New Zealander our most popular philosophy would be wholly unintelligible. The sense, the inward organ, for it is not yet born in him. So is there many a one among us, yes, and some who think themselves philosophers too, to whom the philosophic organ is entirely wanting. To such a man philosophy is a
