“Since knowledge, thinking, and rational action are properties of the individual, since the choice to exercise his rational faculty or not depends on the individual, man’s survival requires that those who think be free of the interference of those who don’t. Since men are neither omniscient nor infallible, they must be free to agree or disagree, to cooperate or to pursue their own independent course, each according to his own rational judgment. Freedom is the fundamental requirement of man’s mind.” — AYN RAND “What is Capitalism?” Capitalism: The Unknown Ideal
To live rationally by reason in society, the individual needs one thing from his fellow citizens: freedom. The freedom to live for oneself, neither sacrificing oneself to others nor sacrificing others to oneself. It is this freedom that unleashes the creative potential of the individual, resulting in a society of universal peace, continuous progress and boundless prosperity.
