The Case Against Objective Value

Reason and Ethics defends the theoretical claim that all values are subjective and the practical claim that human affairs can be conducted fruitfully in full awareness of this.

Joel Marks goes beyond his previous work defending moral skepticism to question the existence of all objective values. This leads him to suggest a novel answer to the Companions in Guilt argument that the denial of morality would mean relinquishing rationality as well. Marks disarms the argument by conceding the irreality of both morality and logic, but is still able to rescue rationality while dispensing with morality on pragmatic grounds. He then offers a positive account of how life may be lived productively without recourse to attributions and assertions of right and wrong, good and bad, and even truth and falsity.

Written in an accessible and engaging style, Reason and Ethics will be of interest to scholars and students working in metaethics as well as to the generally intellectually curious.
