Under the competitive regime, the conditions of success for the individual are not necessarily the same as those for a class.

The success of a class or party presumes a strong element of clannishness, or loyalty to a chief, or adherence to a tenet; whereas the competitive individual can best achieve his ends if he combines the barbarian's energy, initiative, self-seeking and disingenuousness with the savage's lack of loyalty or clannishness.

It may be remarked by the way, that the men who have scored a brilliant (Napoleonic) success on the basis of an impartial self-seeking and absence of scruple, have not uncommonly shown more of the physical characteristics of the brachycephalic-brunette than of the dolicho-blond.

The greater proportion of moderately successful individuals, in a self-seeking way, however, seem, in physique, to belong to the last-named ethnic element.
The temperament induced by the predatory habit of life makes for the survival and fullness of life of the individual under a regime of emulation; at the same time it makes for the survival and success of the group if the group's life as a collectivity is also predominantly a life of hostile competition with other groups.

But the evolution of economic life in the industrially more mature communities has now begun to take such a turn that the interest of the community no longer coincides with the emulative interests of the individual.
