This paper defends the view that trust is a moral attitude, by putting forward the Obligation-Ascription Thesis: If E trusts F to do X, this implies that E ascribes an obligation to F to do X. I explicate the idea of obligation-ascription in terms of requirement and the appropriateness of blame. Then, drawing a distinction between attitude and ground, I argue that this account of the attitude of trust is compatible with the possibility of amoral trust, that is, trust held among amoral persons on the basis of amoral grounds. It is also compatible with trust adopted on purely predictive grounds. Then, defending the thesis against a challenge of motivational inefficacy, I argue that obligation-ascription can motivate people to act even in the absence of definite, mutually-known agreements. I end by explaining, briefly, the advantages of this sort of moral account of trust over a view based on reactive attitudes such as resentment.

In this paper, I consider a form of skepticism that has a permissive conclusion, according to which we are rationally permitted to suspend judgment in an area, or to have beliefs in that area. I argue that such a form of skepticism is resistant to some traditional strategies of refutation. It also carries a benefit, namely that it increases voluntary control over doxastic states by introducing options, and therefore greater freedom, into the realm of belief. I argue that intellectual preferences and dispositions provide decisive reasons that can settle our doxastic states in such cases.

A person presented with adequate but not conclusive evidence for a proposition is in a position voluntarily to acquire a belief in that proposition, or to suspend judgment about it. The availability of doxastic options in such cases grounds a moderate form of doxastic voluntarism not based on practical motives, and therefore distinct from pragmatism. In such cases, belief-acquisition or suspension of judgment meets standard conditions on willing: it can express stable character traits of the agent, it can be responsive to reasons, and it is compatible with a subjective awareness of the available options

As a moral philosopher, the perspective I will take in this chapter is one of argumentation and informed judgment about two main questions: whether individuals should ever choose to conduct human embryonic stem cell research, and whether the law should permit this type of research. I will also touch upon a secondary question, that of whether the government ought to pay for this type of research. I will discuss some of the main arguments at stake, and explain how the ethical conflict over these questions differs from the political conflict over them. I will be guided throughout by the assumption that the unique scientific and clinical promise of human embryonic stem cell research is significant. Those who have doubts about this assumption should consult other chapters in this volume in which the issue is addressed directly. I begin with one of the basic facts relevant to the ethical issue of stem cell research: you and I, along with everybody else we know, developed out of clumps of primordial cells, which happen to be the very same clumps that serve as the source for human embryonic stem cells in the laboratory. Let us call these “source cells” for short, since they can be used in this way. Each individual has developed into whatever she is now out of a one-celled animal, which then became a blastocyst, a multi-celled human embryo. These blastocysts are partly made up of an inner mass of cells, and the body of every adult person has developed out of this inner mass. It is this very same clump from the inner part of the blastocyst that consists of source cells for human embryonic stem 1 cell research. These cells can be extracted and grown into a laboratory specimen of extraordinary interest to scientists. Before discussing the significance of the fact that all humans originate from these source cells, it is useful to begin by asking some perhaps rather simple-minded questions about how any one of us knows this fact to be true in the first place. How do I know that I developed from a single cell, and then a blastocyst? In my own case, the main way I know this is that other people have told me so..
