The subjectivist theory of ethics is, strictly speaking, not a theory, but a negation of ethics.
And more: it is a negation of reality, a negation not merely of man’s
existence, but of all existence. Only the concept of a fluid, plastic,
indeterminate, Heraclitean universe could permit anyone to think or to preach
that man needs no objective principles of action—that reality gives him a
blank check on values—that anything he cares to pick as the good or the evil,
will do—that a man’s whim is a valid moral standard, and that the only
question is how to get away with it. The existential monument to this theory
is the present state of our culture.
