By way of preface to an account of sex differences it is well to note that their existence does not necessarily imply in any case the advisability of differences in school and home training, and, on the other hand, that even if the mental make-up of the sexes were identical it might still be wisest to educate them differently. On the other hand, two boys might be identical in mental structure, yet their education might best be very different if we wished to make one of them a chemist and the other a psychologist. The chapter should properly be devoted exclusively to the differences necessarily produced by sex. Those produced by virtue of the adventitiously different training which boy and girl undergo belong in Chapter XIII. So far as may be, such a separation of differences due to sex-nature from those due to our traditional treatment of the sexes is in fact made. But in many cases where the amount of the difference that is to be credited to training is doubtful, the difference will be described in the present chapter, the discount to be made being left to the reader's judgment.
