One can have faith in someone, believe in someone and trust someone, and these notions seem closely related. Any account of faith should then address its relation to trust and belief. Like trust, faith can similarly have propositional and relational forms. One can have faith that God is good and faith in God; one can trust that another will do something and trust them to do it. Starting from a comparison between these forms of faith and trust, this paper proposes a philosophical analysis of faith and its relation to trust and belief.

According to the Assurance Theory of testimony, in telling an audience something, a speaker offers their assurance that what is told is true, which is something like their guarantee, or promise, of truth. However, speakers also tell lies and say things they do not have the authority to back up. So why does understanding tellings to be a form of assurance explain how tellings can provide a reason for belief? This paper argues that reasons come once it is recognised that tellings are trusted. And the logic by means of which trust gives reason to believe is quite general; it applies equally to belief that is based on evidence rather than assurance. Outlining this logic requires the introduction of the idea of epistemic presumptions, whose truth plays the role of ensuring a connection between believer, justification and truth.

We enjoy first-person authority with respect to a certain class of actions: for these actions, we know what we are doing just because we are doing it. This paper first formulates an epistemological principle that captures this authority in terms of trying to act in a way that one has the capacity to act. It then considers a case of effortful action – running a middle distance race – that threatens this principle. And proposes the solution of changing the metaphysics of action: one can keep hold of the idea that we have first-person authority over what we are doing by adopting a disjunctive account of action

Trust is central to our social lives. We know by trusting what others tell us. We act on that basis, and on the basis of trust in their promises and implicit commitments. So trust underpins both epistemic and practical cooperation and is key to philosophical debates on the conditions of its possibility. It is difficult to overstate the significance of these issues. On the practical side, discussions of cooperation address what makes society possible—of how it is that life is not a Hobbesian war of all against all. On the epistemic side, discussions of cooperation address what makes the pooling of knowledge possible—and so the edifice that is science. But trust is not merely central to our lives instrumentally; trusting relations are themselves of great value and, in trusting others, we realize distinctive forms of value. What are these forms of value, and how is trust central to our lives? These questions are explored and developed in this volume, which collects fifteen new essays on the philosophy of trust. They develop and extend existing philosophical discussion of trust and will provide a reference point for future work on trust.

Faced with evidence that what a person said is false, we can nevertheless trust them and so believe what they say – choosing to give them the benefit of the doubt. This is particularly notable when the person is a friend, or someone we are close to. Towards such persons, we demonstrate a remarkable epistemic partiality. We can trust, and so believe, our friends even when the balance of the evidence suggests that what they tell us is false. And insofar as belief is possible, it is also possible to acquire testimonial knowledge on those occasions when the friends know what they tell us. This paper seeks to explain these psychological and epistemological possibilities.

As sources of knowledge, perception and testimony are both vulnerable to sceptical arguments. To both arguments a Moorean response is possible: both can be refuted by reference to particular things known by perception and testimony. However, lies and dreams are different possibilities and they are different in a way that undercuts the plausibility of a Moorean response to a scepticism of testimony. The condition placed on testimonial knowledge cannot be trivially satisfied in the way the Moorean would suggest. This has substantial implications for any non-sceptical epistemological theory of testimony.

Testimony is a source of knowledge. On many occasions, the explanation of one’s knowing that p is that a speaker, S, told one that p. Our testimonial sources—the referents of ‘S’—can be other individuals, and they can be collectives; that is, in addition to learning from individuals, we learn things from committees, commissions, councils, clubs, teams, research groups, departments, administrations, churches, states and other social groups. North Korea might make a declaration about its missile programme, the church about the ordination of women priests, the council about its deficit, the research group about its findings, and so on. We will look at a few examples in detail shortly, but the starting point is that social groups can be a source of testimony, and we can learn things from such collective testimony. The question this paper pursues is, what explains our learning that p from collective testimony to p?

The assumption that we largely lack reasons for accepting testimony has dominated its epistemology. Given the further assumption that whatever reasons we do have are insufficient to justify our testimonial beliefs, many conclude that any account of testimonial knowledge must allow credulity to be justified. In this paper I argue that both of these assumptions are false. Our responses to testimony are guided by our background beliefs as to the testimony as a type, the testimonial situation, the testifier's character and the truth of the proposition testified to. These beliefs provide reasons for our responses. Thus, we usually do have reasons, in the sense of propositions believed, for accepting testimony and these reasons can provide evidence for the testimonial beliefs we form.

One thing wrong with lying is that it can be manipulative. Understanding why lying can be a form of manipulation involves understanding how our telling someone something can give them a reason to believe it, and understanding this requires seeing both how our telling things can invite trust and how trust can be a reason to believe someone. This paper aims to outline the mechanism by means of which lies can be manipulative and through doing so identify a unique reason for accepting testimony; a reason based on trusting a speaker’s telling.

Most action can be explained in Humean or teleological terms; that is, in most cases, one can explain why someone acted by reference to that person’s beliefs and desires. However, trusting and being trustworthy are actions that do not permit such explanation. The action of trusting someone to do something is a matter of expecting someone to act for certain reasons, and acting trustworthily is one of acting for these reasons. It is better to say that people act out of trust, rather than for some end. Thus, teleological considerations do not suffice to trust. This is the negative claim of the paper. Its positive proposal is an account of the practical rationality of trust. The key idea is that in trusting one takes on commitments, not merely to act in certain way, but also to premise one’s practical reasoning on a trust-based view of the interaction situation.
