To further the end of this transformation of man we should

To further the end of this transformation of man we should
become familiar with the inborn springs to action, those
fundamental tendencies which we call instincts, for we live
more largely than is generally supposed by instinct and less by
reason. All of the organic cravings, hungers, needs, should be
thoroughly understood so that they may be effectively used.
And, finally, the laws of intellect must be at our command if
we are to meet the endlessly varying and puzzling situations of
life profitably and with the measure of adequacy our reason
would seem to justify.
