 So, contrary to Foot, Nietzsche is not claiming that people are actually too altruistic and too egalitarian in their practice; he is worried that (as a consequence of the slave revolt in morals, etc.) they are now “imprisoned among….concepts” of equality and altruism, and that this conceptual vocabulary of value is itself the obstacle to the realization of certain forms of human excellence. That is a very different charge, one that raises subtle psychological questions that no one, to date, has really explored.
