I take it that most (though not all) non-theists assume that atheism does not entail nihilism. More specifically, most non-theists don’t believe that denying the existence of God or the immortality of the soul entails that truth, love, beauty, goodness, and justice are empty words.
But as we’ve seen in numerous discussions, the anti-materialist holds that this commitment is not one to which we are rationally entitled. Rather, the anti-materialist seems to contend, someone who denies that there is any transcendent reality beyond this life cannot be committed to anything other than affirmation of power (or maximizing individual reproductive success) for its own sake.
The question is, why is the anti-materialist mistaken about what non-theists are rationally entitled to? (Anti-materialists are also welcome to clarify their position if I’ve mischaracterized it.)
