It is not illuminating to treat the ordering of values like the topography of the moon which can be established by simply training a telescope on one’s object, or, more satisfactorily, by going there. The sort of values that one is concerned to establish in a systematic axiology are ineluctable, framework values, things presupposed in all rational choice, and indispensable to a complete account of anything whatsoever (Axiological Ethics, pp. 79-80).
