“In regard to nature, “to accept what I cannot change” means to accept the metaphysically given; “to change what I can” means to strive to rearrange the given by acquiring knowledge—as science and technology (e.g., medicine) are doing; “to know the difference” means to know that one cannot rebel against nature and, when no action is possible, one must accept nature serenely. . . . What one must accept is the fact that the minds of other men are not in one’s power, as one’s own mind is not in theirs; one must accept their right to make their own choices, and one must agree or disagree, accept or reject, join or oppose them, as one’s mind dictates. The only means of “changing” men is the same as the means of “changing” nature: knowledge—which, in regard to men, is to be used as a process of persuasion, when and if their minds are active; when they are not, one must leave them to the consequences of their own errors. . . .
To deal with men by force is as impractical as to deal with nature by persuasion.”
“The Metaphysical and the Man-made” by Ayn Rand
