generation as result of imitation and training. If it is unjust "to condemn a whole [italics]people[end italics]" meaning thereby a political group, how much more hazardous is it, as some sensational writers have not hesitated to do, to pass judgment as to the relative genetic inferiority or superiority of different [italics]races[end italics]. If within each human social group the geneticist finds it impossible to discover, with any reasonable certainty, the genetic basis behavior, the problems must seem extraordinarily difficult when groups contrasted with each other where the differences are obviously connected not only with material advantages and disadvantages resulting from location, climate, soil, and mineral wealth, but with traditions, customs, religions, taboos, conventions, and prejudices. A little goodwill might seem more fitting in treating these complicated questions than the attitude adopted by some of the modern race-propagandists. [end]
