ENDS AND MEANS husbands. Discussing this fact, Dr. Unwin hazards the opinion 'that it was the unequal fate of women, not the compulspry continence, that caused the downfall of absolute monogamy. No society has yet succeeded in regulating the relations between the sexes in such a way as to enable sexual opportunity to remain at a minimum for an extended period. The inference I draw from the historical evidence is that, if ever such a result should be desired, the sexes must first be placed on a footing of complete legal equality.9 In this very brief summary I have certainly done much less than justice to Dr. Unwin's very remarkable book; but though doing it less than justice, I do not think that I have misrepresented its main conclusions. The evidence for these conclusions is so full, that it is difficult to see how they can be rejected. They are conclusions which will certainly seem unpalatable to the middle-raged relics, of a liberal generation. Such liberals are liberals, not only politically, but also in the sense in which Shakespeare's 'liberal shepherds * (the ones who called wild arums by a grosser name than dead-men's fingers) were liberal. They have been * heard to declare,* very frequently and loudly, that they 'wish to enjoy the advantages of high culture and to abolish compulsory continence/ Living as they do upon the capital of energy accumulated by a previous generation of monpgamists, whose wives came to them as virgiqes zntactae, they can make the best of both worlds during their own lifetime. Dr. Unwin's researches have made it certain, however, that it will be impossible for their children to go on making the best of both worlds. If Dr. Unwin's conclusions are well founded—and it is difficult to believe that they are not—how do they fit into our-general ethical scheme? The first significant fact to be noticed is that 'the continence caused the thought, not the thought the continence.5 Zoistic societies live in a 3M
