Alarmed by the growing intransigence of public moral discussion, I undertook to describe in Moral Fictionalism what moral practice would become if such intransigence became entrenched in the norms governing public moral discourse.

It is an account of what moral practice would become if we lack sufficient respect to try to understand one another. Public lecture for non-philosophers
