This book defends a form of ethical intuitionism, according to which (i) there are objective moral truths; (ii) we know some of these truths through a kind of immediate, intellectual awareness, or "intuition"; and (iii) our knowledge of moral truths gives us reasons for action independent of our desires. The author rebuts all the major objections to this theory and shows that the alternative theories about the nature of ethics all face grave difficulties.

I defend the principle of Phenomenal Conservatism, on which appearances of all kinds generate at least some justification for belief. I argue that there is no reason for privileging introspection or intuition over perceptual experience as a source of justified belief; that those who deny Phenomenal Conservatism are in a self-defeating position, in that their view cannot be both true and justified; and that thedemand for a metajustification for Phenomenal Conservatism either is an easily met demand, or is an unfair (...) or question-begging one.

This chapter begins with a weak understanding of intuitions as beliefs that do not result from more familiar sources, but that the person currently holds simply because the proposition believed seems true to the person upon due consideration. Nearly all moral inquiry makes significant use of moral intuitions. Reflective equilibrium is perhaps the most sophisticated intuitionistic approach to moral inquiry. It modifies the usual understanding of reflective equilibrium by arguing that inquirers must not merely mold their moral intuitions into a (...) coherent system via a process of mutual adjustment, but must also strive to enhance their competence at making moral judgments. It then considers and rejects an argument for the reliability of moral intuitions that takes them to provide evidence regarding our own moral concepts. Finally, it defends reflective equilibrium by arguing that there is no sensible alternative to accepting the intuitions we have after full reflection, which is, in essence, what reflective equilibrium does.

In this companion volume to Warrant: The Current Debate, Plantinga develops an original approach to the question of epistemic warrant; that is what turns true belief into knowledge. He argues that what is crucial to warrant is the proper functioning of one's cognitive faculties in the right kind of cognitive environment.

The contributions in this volume make an important effort to resurrect a rather old fashioned form of foundationalism. They defend the position that there are some beliefs that are justified, and are not themselves justified by any further beliefs. This epistemic foundationalism has been the subject of rigorous attack by a wide range of theorists in recent years, leading to the impression that foundationalism is a thing of the past. DePaul argues that it is precisely the volume and virulence of (...) the assaults which points directly to the strength and coherence of the position. (shrink)
