The Biology of the Race Problem

'...Boas selected and excluded facts in accordance with their usefulness for his purpose. Consider the following: In the 1911 edition of his 'The Mind of Primitive Man', Boas wrote, 'Differences of structure must be accompanied by differences of function, physiological as well as psychological; and, as we found clear evidence of differences in structure between the races, so we must anticipate that the differences in mental characteristics will be found.' He excluded this statement, however, from the 1938 edition. With regard to this exclusion, Otto Klineberg,[115] another of Boas' students and followers, stated that '. . . it seems highly probable that Boas changed his mind on this point . . .' Possibly so; but I know of nothing in the development of anatomy or physiology between 1911 and 1938, or since, to justify a change of mind on that point; quite the contrary.' --p81
