Is it legitimate to acquire one’s moral beliefs on the testimony of others? The pessimist about moral testimony says not. But what is the source of the difficulty? Here pessimists have a choice. On the Unavailability view, moral testimony never makes knowledge available to the recipient. On Unusability accounts, although moral testimony can make knowledge available, some further norm renders it illegitimate to make use of the knowledge thus offered. I suggest that Unusability accounts provide the strongest form of pessimist (...) view. I consider and reject five Unavailability accounts. I then argue that any such view will fail. But what is the norm rendering moral testimonial knowledge unusable? I suggest it lies in the requirement that we grasp for ourselves the moral reasons behind a moral view. This demand is one testimony cannot meet, and that claim holds whatever account we offer of the epistemology of testimony. However, while appeal to this requirement forms the most plausible pessimist view, it is another question whether pessimism is correct. (shrink)

Consider the skeptic about the external world. Let’s straightaway concede to such a skeptic that perception gives us no conclusive or certain knowledge about our surroundings. Our perceptual justification for beliefs about our surroundings is always defeasible—there are always possible improvements in our epistemic state which would no longer support those beliefs. Let’s also concede to the skeptic that it’s metaphysically possible for us to have all the experiences we’re now having while all those experiences are false. Some philosophers dispute (...) this, but I do not. The skeptic I want to consider goes beyond these familiar points to the much more radical conclusion that our perceptual experiences can’t give us any knowledge or even justification for believing that our surroundings are one way rather than another.

Looking back on it, it seems almost incredible that so many equally educated, equally sincere compatriots and contemporaries, all drawing from the same limited stock of evidence, should have reached so many totally different conclusions---and always with complete certainty.

Trust enters into the making of a virtuous person in at least two ways. First, unless a child has a sufficiently trusting relationship with at least one adult, it is doubtful that she will be able to become the kind of person who can form ethically responsible relationships with others. Infant trust, as Annette Baier has reminded us, is the foundation on which future trust relationships will be built; and when such trust is irreparably shaken, the adult into whom the (...) child grows may be forever cut off from intimacy. Second, a moral beginner must trust other people's moral judgment while she learns to be good. A child does not learn how to be good on her own. She follows the precepts and examples of others, absorbs the moral values of the community into which she has been born, and relies on others who, with luck, will not lead her astray but will turn out to be trustworthy in offering her guidance and correction. While there is some empirical evidence that children learn about morality better when given reasons in support of what they are being taught, part of what a child is being taught is what counts as a good reason. Thus, no moral beginner could be in a position to assess adequately the cogency of the reasons she given until she has progressed some distance in her education. Until that time, the beginner must rely on other people's judgment. That thrust enters into the making of a morally good person should thus be uncontroversial. I want to defend a much more controversial thesis: needing to trust other people's moral judgment is not just a stage we go through on the way to becoming morally virtuous. If the world of value is complex, and if our access to it is shaped by our experiences, then even among the morally mature there will continue to be a significant role for moral testimony and thus for trust.

Most traditional epistemologists see trust and knowledge as deeply antithetical: we cannot know by trusting in the opinions of others; knowledge must be based on evidence, not mere trust. I argue that this is badly mistaken. Modern knowers cannot be independent and self-reliant. In most disciplines, those who do not trust cannot know. Trust is thus often more epistemically basic than empirical evidence or logical argument, for the evidence and the argument are available only through trust. Finally, since the reliability (...) of testimonial evidence depends on the trustworthiness of the testifier, this implies that knowledge often rests on a foundation of ethics. The rationality of many of our beliefs depends not only on our own character, but on the character of others. (shrink)

Plantinga examines the nature of epistemic warrant; whatever it is that when added to true belief yields knowledge. This volume surveys current contributions to the debate and paves the way for his owm positive proposal in Warrant and Proper Function.

_In Defense of Anarchism_ is a 1970 book by the philosopher Robert Paul Wolff, in which the author defends individualist anarchism. He argues that individual autonomy and state authority are mutually exclusive and that, as individual autonomy is inalienable, the moral legitimacy of the state collapses.

A person sometimes forms moral beliefs by relying on another person''s moral testimony. In this paper I advance a cognitivist normative account of this phenomenon. I argue that for a person''s actions to be morally good, they must be based on a recognition of the moral reasons bearing on action. Morality requires people to act from an understanding of moral claims, and consequently to have an understanding of moral claims relevant to action. A person sometimes fails to meet this requirement (...) when she relies on another person''s moral testimony, and so there are moral limits on such reliance. (shrink)
