The Ancient Chimera of Universal, Absolute, and Objective Value

That seems like the common equivocation of egoist with egotistical. As we know, psychological egoism is not incompatible with non-material values and goals. It is a very naive egoism indeed that produces an egotist.

Likewise, moral nihilism is a meta-ethical position that has no relevance to the actual values the person holds. There are the occasional Jacob Blooms that take a position based on a very superficial understanding of their philosophy, or who ‘overcompensate’ by rejecting the concept of value altogether (an altogether untenable position).

Jacob Bloom’s material pragmatism is not inconsistent with moral nihilism, but is not necessitated by it, just as psychological egoism allows but does not necessitate egotism.
