The doctrine of the equality of the man is a transcendent doctrine: a “dogma,” as we call such doctrines in the field of transcendental religion. It corresponds to no physical reality which we can grasp, it is hardly to be adumbrated even by metaphors drawn from physical objects. We may attempt to rationalise it by saying that what is common to all men is not more important but infinitely more important than the accidents by which men differ. We may compare human attributes to tri-dimensional, and personal attributes to bi-dimensional measurements; we may say that whatever man has of his nature is the standard of man, and we may show that in all such things men are potentially equal. None of these metaphors explains the matter; still less do any of them satisfy the demand of those to whom the dogma may be incomprehensible.
Its truth is to be arrived at (for these) in a negative manner. If men are not equal then no scheme of jurisprudence, no act of justice, no movement of human indignation, no exaltation of fellowship, has any meaning. The doctrine of the equality of man is one which, like many of the great transcendental doctrines, may be proved by the results consequent upon its absence. It is in man to believe it—and all lively societies believe it.
It is certainly not in man to prove the equality of men save, as I have said, by negation; but it demands no considerable intellectual faculty to perceive that, void of the doctrine of equality, the conception of political freedom and of a community’s moral
