In the present text, the author is animated by the desire to put forward deep analysis over political philosophy and political economy. In substance, political philosophy and political economy are unified by similar carrying notions; taxation theory, expectation theory, price system, time preference theory and praxeology are equal to the core of both disciplines. The process of civilization is the aftermath of the instauration of the theory of expectations. The law is the most refined form of expectation. The citizen does build his / her actions by relying on a pre - existent net of ''objective'' expectations. Other forms of expectation are equal, for example, to the market system and welfare. The more society is characterized by the presence of expectations, the more the individual is in a position to put forward high time preference. The individual, in the presence of uneasiness, does act as soon as he/she can in order to solve the latter and thus reach a status of easiness/gratification. The more the individual is successful, the more he/she has a high time preference.
