Note 29 — Chapter IV · THE FRENCH SCHOOL (THE SCHOOL OF THE ENVIRONMENT).

Among the anatomical stigmata observed in criminals in prison there are several which, considered by themselves, have nothing abnormal about them; none of them would serve to characterize criminals. We often find, for example, that murderers have relatively large jaws, which are ordinarily thus an index of a conformation disposed to brutality; “but this brutality is absolutely of the same order as that of men compared with women; it is a masculine characteristic, and the masculine conformation is indubitably favorable to crimes of violence much more than the feminine; but happily it happens that most men, in civilized countries, live under conditions in which their natural brutality does not prevent their being very peaceable citizens, though it would be imprudent to molest them. Very vigorous men are ordinarily endowed with square and very solid jaws; they are men for attack or defense, who may be very useful to society or very harmful, as the case may be. Given to acting vigorously and brutally, this they may be, but inclined to crime they are not, any more than the men with small jaws, whose mildness is often the effect of muscular weakness, and who, though little given to striking and breaking down doors, nevertheless know how to be brutal and violent in their own way.”29
