The understanding is that which conditionates and co-ordinates all things, that which places all things in reciprocal dependence and connection, because it is itself immediate and unconditioned; it inquires for the cause of all things, because it has its own ground and end in itself. Only that which itself is nothing deduced, nothing derived, can deduce and construct, can regard all besides itself as derived; just as only that which exists for its own sake can view and treat other things as means and instruments. The understanding is thus the original, primitive being. The understanding derives all things from God as the first cause; it finds the world, without an intelligent cause, given over to senseless, aimless chance; that is, it finds only in itself, in its own nature, the efficient and the final cause of the world--the existence of the world is only then clear and comprehensible when it sees the explanation of that existence in the source of all clear and intelligible ideas, i.e., in itself. The being that works with design towards certain ends, i.e., with understanding, is alone the being that to the understanding has immediate certitude, self-evidence. Hence that which of itself has no designs, no purpose, must have the cause of its existence in the design of another, and that an intelligent being. And thus the understanding posits its own nature as the causal, first, premundane existence--i.e., being in rank the first but in time the last, it makes itself the first in time also.
