The first of these principles is that the old logic of identity never gives us more than a postmortem dissection of disjecta membra , and that the fullness of life can be construed to thought only by recognizing that every object which our thought may propose to itself involves the notion of some other object which seems at first to negate the first one.
The second principle is that to be conscious of a negation is already virtually to be beyond it. The mere asking of a question or expression of a dissatisfaction proves that the answer or the satisfaction is already imminent; the finite, realized as such, is already the infinite in posse .
Applying these principles, we seem to get a propulsive force into our logic which the ordinary logic of a bare, stark self-identity in each thing never attains to. The objects of our thought now act within our thought, act as objects act when given in experience. They change and develop. They introduce something other than themselves along with them; and this other, at first only ideal or potential, presently proves itself also to be actual. It supersedes the thing at first supposed, and both verifies and corrects it, in developing the fullness of its meaning.
The program is excellent; the universe is a place where things are followed by other things that both correct and fulfill them; and a logic which gave us something like this movement of fact would express truth far better than the traditional school-logic, which never gets of its own accord from anything to anything else, and registers only predictions and subsumptions, or static resemblances and differences. Nothing could be more unlike the methods of dogmatic theology than those of this new logic. Let me quote in illustration some passages from the Scottish transcendentalist whom I have already named.
