Friedrich Nietzsche - On the Genealogy of Morality (Chap. 2.3) lyrics

Secondly, however, and quite separate from the fact that this hypothesis about the origin of the value judgment “good” is historically untenable, it suffers from an inherent psychological contradiction. The utility of the unegoistic action is supposed to be the origin of the praise it receives, and this origin has allegedly been forgotten:—but how is this forgetting even possible? Could the usefulness of such actions at some time or other perhaps just have stopped? The opposite is the case: this utility has rather been an everyday experience throughout the ages, and thus something that has always been constantly re-emphasized. Hence, instead of disappearing from consciousness, instead of becoming something forgettable, it must have pressed itself into the consciousness with ever-increasing clarity. How much more sensible is that contrasting theory (which is not therefore closer to the truth—) which is advocated, for example, by Herbert Spencer: he proposes that the idea “good” is essentially the same as the idea “useful” or “functional,” so that in judgments about “good” and “bad” human beings sum up and endorse the experiences they have not forgotten and cannot forget concerning the useful-functional and the harmful-useless.* According to this theory, good is something which has always proved useful, so that it may a**ert its validity as “valuable in the highest degree,” as “valuable in itself.” This path to an explanation is, as mentioned, also false, but at least the account is inherently sensible and psychologically tenable.
