“We must distinguish between military and political power.Political power is a psychological relation between those who exercise it and those over whom it is exercised. It gives the former control over certain actions of the latter through the influence which the former exert over the latter's minds. That influence may be exerted through orders, threats, persuasion, or a combination of any of these.”

“When we speak of power, we mean man's control over the minds and actions of other men. By political power we refer to the mutual relations of control among the holders of public authority and between the latter and the people at large.”

“Situational variables can exert powerful influences over human behavior, more so that we recognize or acknowledge.”

“In order to exert influence over people, there were other things that could be used besides love. Knowledge seemed to be an equally strong force, perhaps even stronger. Whoever possessed knowledge not only had power over the changeable passions of people, but also power over their thinking, over their minds, hearts and souls.”

“Our worst fears, like our greatest hopes, are not outside our powers, and we can come in the end to triumph over the former and to achieve the latter.”

“Be as careful of the books you read, as of the company you keep; for your habits and character will be as much influenced by the former as the latter.”
