2. On the Moral Justification
“The moral justification of capitalism does not lie in the altruist claim that it represents the best way to achieve “the common good.” It is true that capitalism does—if that catch-phrase has any meaning—but this is merely a secondary consequence. The moral justification of capitalism lies in the fact that it is the only system consonant with man’s rational nature, that it protects man’s survival qua man, and that its ruling principle is: justice.” –Capitalism, the Unknown Ideal
“The action required to sustain human life is primarily intellectual: everything man needs has to be discovered by his mind and produced by his effort. Production is the application of reason to the problem of survival . . . .
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.” –Capitalism, the Unknown Ideal
