Or: a materialist atheist pantses an idealist atheist.

For [Harris] the two things are the same: on the one hand objective moral truth (universal morality), and on the other hand scientific facts about what increases wellbeing and what doesn’t. […] I think the two things are very different from one another.

Just as religion is not something that depends on the existance of god, but is a specific social practice, a specific form of communication that relates to a certain unrealistic assumption; likewise morality is a specific discourse, a specific way of acting, that relates to and derives from making unrealistic assumptions about something that doesn’t exist.
