 this to the uncertainty of every possible result, is in the end irrational. For the assertion, “I am sure that I am everywhere fallible,” contradicts itself, and would revive a familiar Greek dilemma. And if we modify the assertion, and instead of “everywhere” write “in general,” then the desired conclusion will not follow. For unless, once more falsely, we assume that all truths are much the same, and that with regard to every point error is equally probable, fallibility in general need not affect a particular result. In short within theory we must decline to consider the chance of a fundamental error. Our assertion of fallibility may serve as the expression of modest feeling, or again of the low estimate we may have formed of the intellect’s value. But such an estimate or such a feeling must remain outside of the actual process of theory. For, admitted within, they would at once be inconsistent and irrational.

2. An asserted possibility in the next place must have some meaning. A bare word is not a possibility, nor does any one ever knowingly offer it as such. A possibility always must present us with some actual idea.

3. And this idea must not contradict itself, and so be self-destructive. So far as it is seen to be so, to that extent it must not be taken as possible. For a possibility qualifies the Real, and must therefore not conflict with the known character of its subject. And it is useless to object here that all appearance is self-contradictory. That is true, but, as self-contradictory and so far as it is so, appearance is not a real or possible predicate of Reality. A predicate which contradicts itself is, as such, not possibly real. In order to be real, its particular nature must be modified and corrected. And this
