ABSTRACT
Understood in this way, the principle of equality does not prescribe positively that all human beings be treated alike; it is a presumption against treating them differently, in any respect, until grounds for distinction have been shown. It does not assume, therefore, a quality which all men have to the same degree, which is the ground of the presumption, for to say that there is a presumption means that no grounds need be shown. The onus of justification rests on whoever would make distinctions.
