" Miracles are sensuously cognizable events, not comprehensible on the ground of the causality of nature as such, but essentially on the ground of God's free action alone.
He facilitated this awkward transition by adding to Kant's a priori forms of space and time an " a priori form of alternative causality," or, as he also called it, " an intuition of causality involved in the elementary exercise of perception," which is the key to his whole philosophy.
Matter, as an abstract, unperceived substance or cause, is shown to be impossible, an unreal conception; true substance is affirmed to be conscious spirit, true causality the free activity of such a spirit, while physical substantiality and causality are held to be merely arbitrary, though constant, relations among phenomena connected subjectively by suggestion or association, objectively in the Universal Mind.
At the same time, true: to the hypothesis of " immanence," he rigidly confines these categories to the given data, and altogether avoids the inconsistent tendency of Kant to transfer causality from a necessary relation between phenomena to a neces-' sary relation between phenomena and things in themselves as their causes.
He uses this psychical causality to carry out his voluntarism into detail, regarding it as an agency of will directed to ends, causing association and understanding, and further acting on a principle which he calls the heterogony of ends; remarking very truly that each particular will is directed to particular ends, but that beyond these ends effects follow as unexpected consequences, and that this heterogony produces social effects which we call custom.
