Reduced to abstract logical categories, the creative principle in God expresses nothing further than the tautological proposition: the different can only proceed from a principle of difference, not from a simple being. However the Christian philosophers and theologians insisted on the creation of the world out of nothing, they were unable altogether to evade the old axiom--"Nothing comes from nothing," because it expresses a law of thought. It is true that they supposed no real matter as the principle of the diversity of material things, but they made the divine understanding (and the Son is the wisdom, the science, the understanding of the Father)--as that which comprehends within itself all things as spiritual matter--the principle of real matter. The distinction between the heathen eternity of matter and the Christian creation in this respect is only that the heathens ascribed to the world a real, objective eternity, whereas the Christians gave it an invisible, immaterial eternity. Things were before they existed positively,--not, indeed, as an object of sense, but of the subjective understanding. The Christians, whose principle is that of absolute subjectivity, conceive all things as effected only through this principle. The matter posited by their subjective thought, conceptional, subjective matter, is therefore to them the first matter,--far more excellent than real, objective matter. Nevertheless, this distinction is only a distinction in the mode of existence. The world is eternal in God. Or did it spring up in him as a sudden idea, a caprice? Certainly man can conceive this too; but, in doing so, he deifies nothing but his own irrationality. If, on the contrary, I abide by reason, I can only derive the world from its essence, its idea, i.e., one mode of its existence from another mode; in other words, I can derive the world only from itself. The world has its basis in itself, as has everything in the world which has a claim to the name of species. The differentia specifica, the peculiar character, that by which a given being is what it is, is always in the ordinary sense inexplicable, undeducible, is through itself, has its cause in itself.
