s and ingenious cutting, jabbing, and
bruising appliances to compensate. His life was a life of strains,
both giving and taking, and under the stress he had developed
offensive and defensive weapons. There is, however, no radical
difference, simply a difference in object and intensity of stimulus,
between handling and making weapons and handling and making tools.
So, when man was obliged to turn his attention to the agriculture
and industries practiced by primitive woman he brought all his
technological skill and a part of his technological interest to bear
on the new problems. Women had been able to thrust a stick into the
earth and drop the seed and await a meager harvest. When man turned
his attention to this matter, his ingenuity eventually worked out a
remarkable combination of the animal, mineral, and vegetable kingdoms:
with the iron plow, drawn by the ox, he upturned the face of the
earth, and produced food stuffs in excess of immediate demands, thus
creating the conditions of culture.

The destructive habits of the male nature were thus converted
under the stress of diminishing nutrition to the habits represented
primarily by the constructive female nature, and the inventive faculty
developed through attention to destructive mechanical aids was now
applied equally to the invention of constructive mechanical aids.

SEX AND PRIMITIVE MORALITY

The function of morality is to regulate the activities of associated
life so that all may have what we call fair play. It is impossible to
think of morality aside from expressions of force, primarily physical
force. "Thou shalt not kill; thou shalt not steal; thou shalt not bear
false witness; thou shalt not commit adultery; thou shalt not remove
the ancient landmark;" and all approvals and disapprovals imply
that the act in question has affected or will affect the interest of
others, or of society at large, for better or for worse. And since
morality goes back so directly to forms of activity and their
regulation, we may expect to find that the motor male and the more
stationary female have had a different relation to the development of
a moral code.

As between nutrition and reproduction, in the struggle for life,
nutrition plays a larger role--in volume, at any rate--in the
life-history of the individual. A consideration of the causes of the
modification of species in nature shows that the changes in morphology
and habit of the animal which relate to food-gett
