K. Lenk's book represents a significant effort to redefine, based on contemporary data of evolution and progress, the relationships between political science and sociology, as well as the cognitive field of political sociology.

He, like many other scholars, sees political sociology penetrating, as an autonomous branch, towards the cognitive fields of political science and those of sociology.

In this "expansive" inclination, political sociology develops its own concepts and presents its own cognitive goals, thereby enriching the cognitive foundation of the other two closely related sciences.
