Since the world is developed in time, or change, the perfection of the faculty that places men in relation with the world will necessarily be the greatest possible mutability and extensiveness. Since personality is permanence in change, the perfection of this faculty, which must be opposed to change, will be the greatest possible freedom of action (autonomy) and intensity. The more the receptivity is developed under manifold aspects, the more it is movable and offers surfaces to phaenomena, the larger is the part of the world seized upon by man, and the more virtualities he develops in himself. Again, in proportion as man gains strength and depth, and depth and reason gain in freedom, in that proportion man TAKES IN a larger share of the world, and throws out forms outside himself. Therefore his culture will consist, first, in placing his receptivity on contact with the world in the greatest number of points possible, and is raising passivity to the highest exponent on the side of feeling; secondly, in procuring for the determining faculty the greatest possible amount of independence, in relation to the receptive power, and in raising activity to the highest degree on the side of reason. By the union of these two qualities man will associate the highest degree of self-spontaneity (autonomy) and of freedom with the fullest plenitude of existence, and instead of abandoning himself to the world so as to get lost in it, he will rather absorb it in himself, with all the infinitude of its phenomena, and subject it to the unity of his reason. But man can invert this relation, and thus fail in attaining his destination in two ways. He can hand over to the passive force the intensity demanded by the active force; he can encroach by material impulsion on the formal impulsion, and convert the receptive into the determining power. He can attribute to the active force the extensiveness belonging to the passive force, he can encroach by the formal impulsion on the material impulsion, and substitute the determining for the receptive power. In the former case, he will never be an Ego, a personality; in the second case, he will never be a Non-Ego, and hence in both cases he will be NEITHER ONE NOR THE OTHER, consequently he will nothing.
