To these norms is to be added another broad principle of human nature—the predatory animus—which in point of generality and of psychological content lies between the two just named. The effect of the latter in shaping the accepted scheme of life is yet to be discussed.
The canon of reputability, then, must adapt itself to the economic circumstances, the traditions, and the degree of spiritual maturity of the particular class whose scheme of life it is to regulate.
