II. THE PROBLEM OF THE BIRTH SUPPLY

It may be urged that this attempt to whittle down the “inherited craving” to a habit does not meet Mr. Reid’s argument from the gradual increase of resisting power in races subjected to alcoholic temptation, an increase due to the elimination of all the more susceptible individuals. There can be no denying that those nations that have had fermented drinks longest are the soberest, but that, after all, may be only one aspect of much more extensive operations. The nations that have had fermented drinks the longest are also those that have been civilized the longest. The passage of a people from a condition of agricultural dispersal to a more organized civilization means a very extreme change in the conditions of survival, of which the increasing intensity of temptation to alcoholic excess is only one aspect. Gluttony, for example, becomes a much more possible habit, and many other vices tender death for the first time to the men who are gathering in and about towns. The city demands more persistent, more intellectualized and less intense physical desires than the countryside. Moral qualities that were a disadvantage in the dispersed stage become advantageous in the city, and conversely. Rugged independence ceases to be helpful, and an intelligent turn for give and take, for collaboration and bargaining, makes increasingly for survival. Moreover, there grows very slowly an indefinable fabric of traditional home training in restraint that is very hard to separate in analysis from mental heredity. People who have dwelt for many generations in towns are not only more temperate and less explosive in the grosser indulgences, but more urbane altogether. The drunken people are also the “uncivil” peoples and the individualistic peoples. The great prevalence of drunkenness among the upper classes two centuries ago can hardly have been bred out in the intervening six or seven generations, and it is also a difficult fact for Mr. Reid that drunkenness has increased in France. In most of the cases cited by Mr. Reid a complex of operating forces could be stated in which the appearance of fermented liquors is only one factor, and a tangle of consequent changes in which a gradually increasing insensibility to the
