Republic
"The American system is not a democracy. It is a constitutional republic. A democracy, if you attach meaning to terms, is a system of unlimited majority rule . . . a form of collectivism, which denies individual rights . . . . The American system is a constitutionally limited republic, restricted to the protection of individual rights. In such a system, majority rule is applicable only to lesser details, such as the selection of certain personnel. But the majority has no say over the basic principles governing the government. It has no power to ask for or gain the infringement of individual rights."
~ Leonard Peikoff, The Philosophy of Objectivism
Individual Rights
"A “right” is a moral principle defining and sanctioning a man’s freedom of action in a social context. There is only one fundamental right (all the others are its consequences or corollaries): a man’s right to his own life. Life is a process of self-sustaining and self-generated action; the right to life means the right to engage in self-sustaining and self-generated action—which means: the freedom to take all the actions required by the nature of a rational being for the support, the furtherance, the fulfillment and the enjoyment of his own life. (Such is the meaning of the right to life, liberty and the pursuit of happiness.)
The concept of a “right” pertains only to action—specifically, to freedom of action. It means freedom from physical compulsion, coercion or interference by other men."
