In all periods of transition which a process in change in progress implies, we expect to find cases where the conservative force of tradition from the past has delayed recognition of the too novel present, and we discover that circumstances have moved too rapidly for the intelligence of the times. If we keep this fact in view, we have thus seemed to find a natural explanation of the knotty point which was the cause of dispute between Mr. Morgan and Mr. McLennan,[12] and we may thus venture to say that each was both wrong and right in his views of the classificatory system in general. Each has mistaken a part for a whole, and they were ignorant that they were upholding two sides of the same question. Mr. Morgan was in error in assuming the system’s too intimate connection with a determination of affinities in blood, in relation to which primarily, as we hope to have shown, it had really neither purpose nor aim, as also in his too hasty assumption of a consanguine family founded on brother and sister incest, based on a mere conjectural solution of a verbal detail, an assumption which he himself acknowledges had no other foundation. Mr. McLennan was in error in maintaining that the classificatory system concerned terms of address alone. To quote his own words: ‘What duties or rights are affected by the “relationships” comprised in the classificatory system? Absolutely none; they are barren of consequences, except indeed as comprising a code of courtesies and ceremonial addresses in social intercourse.’ On the other hand, as we have tried to show, the system had precisely both intention and effect in regulation, as regards sexual feeling, which is the strongest passion in nature. And yet each disputant again was right in a degree, for, in later times, the classificatory distinctions really served as terms of address as regards the clan [tribe?], whilst again the primitive terms, which simply describe generations of persons in their relation to the group, were afterwards, by philological transmutation, to come to have a more definite meaning expressing the sense of the personal parent.
