If we try to classify recognisable human qualities in these terms, a superficial glance suggests the following points. The first thing that strikes us, in broad outlines, is the psychological contrast between the sexes. It is a stale cliché, but all the more important because it is dredged up out of general experience, that women are mostly led by their feelings, while men follow their reason. Men are more ‘prudent’. They alone have the capacity for calculation, cool (abstract) thought, deliberation, strategic thinking and logic. As a rule, women are not much good at these things. They are thus lacking in the basic prerequisite of calculative will. It is not true that people can only succeed in being really active, independent of nature and with some degree of mastery over it, by means of abstract thought and rational calculation. But it is true that such activity begets and develops rational calculation and is [in turn] infinitely increased with its aid. Now the role of the male is more active not only among human beings, but certainly among other mammals, and in all cases where the female has to devote a large part of her time and attention to her brood. The male is then responsible for providing food and for fighting, especially when he has to attack and plunder or even kill his rivals in order to acquire a mate.
