Right and WrongIf moral realism (the notion that moral values exist independently of human minds) is false, then there is no reason to talk of “morality” as if it were something distinct from personal preference.  Given moral relativism, moral beliefs are just personal/social preferences.  What we call “morality” is nothing more than a set of personal preferences regarding certain dispositions and behaviors, or a set of normative social preferences – both of which are subjective in nature and can change over time.  Saying “vanilla ice-cream is better than chocolate ice-cream” and saying “telling the truth is better than lying” are the exact same kind of claims: personal, subjective preference.  No oughts are involved.  They are just autobiographic or (to possibly coin a new term) sociobiographic statements.  They describe rather than prescribe.
