The necessary tendence therefore of all natural philosophy is from nature to intelligence; and this, and no other is the true ground and occasion of the instinctive striving to introduce theory into our views of natural phænomena. The highest perfection of natural philosophy would consist in the perfect spiritualization of all the laws of nature into laws of intuition and intellect. The phænomena (the material) must wholly disappear, and the laws alone (the formal) must remain. Thence it comes, that in nature itself the more the principle of law breaks forth, the more does the husk drop off, the phenomena themselves become more spiritual and at length cease altogether in our consciousness. The optical phænomena are but a geometry, the lines of which are drawn by light, and the materiality of this light itself has already become matter of doubt. In the appearances of magnetism all trace of matter is lost, and of the phænomena of gravitation, which not a few among the most illustrious Newtonians have declared no otherwise com-
