ABSTRACT
The science of economics needs only its own behavioristic foundations. Habitual Assumptions are as deep as it is necessary to go. Custom means, in economics, that the individual cannot make a living or continue in business unless he adapts himself to what his competitors, customers, employees and others are doing. The economic sanction operates through scarcity of alternatives, often more powerful than a legal mandate sanctioned by the physical force of sovereignty. There are the moral sanctions of collective opinion, revealing themselves in their characteristic similarity of acts without economic pressure or governmental duress. Individuals are no longer the mere individuals of the classical economic theory—they are members, citizens of a concern, with rights and liberties conferred or withheld by associated action. Economists recognize three change abilities in the principle of scarcity, namely, degree, relativity and measurability. Degree varies from extreme scarcity to excessive abundance of a particular quantity—the principle of polarity.
