"Can we assume that a thing is right if it is legal? But slavery was once legal; Nazism was legal. Well, can we assume a thing is right if it is endorsed by majority rule? But a lynch mob is majority rule. Is a thing sure to be right, then, if it comes about through the democratic process? But fascist dictator Juan Perón of Argentina was democratically elected by majority rule on two occasions. . . . Well, how about the Constitution? But again we run into difficulties, for the Constitution can be amended to say anything the society wishes it to say. Suppose, for example, the Constitution were amended to permit the lynching of blacks—would this practice become ethically correct merely because the Constitution permitted it? The moral basis of capitalism is the right of each individual to live his own life, for his own sake."
