The intrinsic theory and the subjectivist theory (or a mixture of both) are the necessary base of every dictatorship, tyranny, or variant of the absolute state. Whether they are held consciously or subconsciously—in the explicit form of a philosopher’s treatise or in the implicit chaos of its echoes in an average man’s feelings—these theories make it possible for a man to believe that the good is independent of man’s mind and can be achieved by physical force.
If a man believes that the good is intrinsic in certain actions, he will not hesitate to force others to perform them. If he believes that the human benefit or injury caused by such actions is of no significance, he will regard a sea of blood as of no significance. If he believes that the beneficiaries of such actions are irrelevant (or interchangeable), he will regard wholesale slaughter as his moral duty in the service of a “higher good.” It is the intrinsic theory of values that produces a Robespierre, a Lenin, a Stalin, or a Hitler. It is not an accident that Eichmann was a Kantian.
If a man believes that the good is a matter of arbitrary, subjective choice, the issue of good or evil becomes, for him, an issue of: my feelings or theirs? No bridge, understanding, or communication is possible to him. Reason is the only means of communication among men, and an objectively perceivable reality is their only common frame of reference; when these are invalidated (that is, held to be irrelevant) in the field of morality, force becomes men’s only way of dealing with one another. If the subjectivist wants to pursue some social ideal of his own, he feels morally entitled to force men “for their own good,” since he feels that he is right and that there is nothing to oppose him but their misguided feelings.
Thus, in practice, the proponents of the intrinsic and the subjectivist schools meet and blend. It is doubtful whether anyone can hold either of these theories as an actual, if mistaken, conviction. But both serve as a rationalization of power-lust and of rule by brute force, unleashing the potential dictator and disarming his victims.
