…to say that one term, say u, is logically simpler than another, say w, means precisely that the affirmation of w concerning any subject implies the affirmative truth of u concerning the same subject, while the affirmation of u does not reciprocally imply the affirmative truth of w; and it may be remarked, by the way, that disquiparance is thus necessarily involved in logical simplicity: but we need not argue from that principle.
