(disagreement with premise 1.)

I disagree with upholding what is worthwhile.

A. I uphold what is unworthwhile instead.


B. I cannot decide whether to uphold what is worthwhile or what is unworthwhile.


C. Whether I uphold the worthwhile or not depends on what you mean by "the worthwhile."

This is a perfectly legitimate concern. However premise 2. and disagreements with it consider the main philosophical senses of "the worthwhile," so return to the main argument.
