There is not only moral disagreement among ordinary people: there is also moral disagreement among philosophers. Since philosophers might seem to be in the best possible position to reach the truth about morality, such disagreement may suggest that either there is no single truth about morality, or at least if there is, it is unknowable. The goal of this paper is to rebut this argument: the best explanation of moral disagreement among philosophers is quite compatible with the thesis that many moral truths are widely known.

Intuitively, it seems that some belief-forming practices have the following three properties: 1. They are rational practices, and the beliefs that we form by means of these practices are themselves rational or justified beliefs. 2. Even if in most cases these practices reliably lead to correct beliefs (i.e., beliefs in true propositions), they are not infallible: it is possible for beliefs that are formed by means of these practices to be incorrect (i.e., to be beliefs in false propositions). 3. The rationality of these practices is basic or primitive. That is, the rationality of these practices is not due simply to the availability, by means of some process of reasoning that relies purely on other practices, of a rational or justified belief in the reliability of these practices. How can there be such practices? This paper offers an answer to that question.

What exactly is reasoning? Like many other philosophers, I shall endorse a broadly causal conception of reasoning. Reasoning is a causal process, in which one mental event (say, one’s accepting the conclusion of a certain argument) is caused by an antecedent mental event (say, one’s considering the premises of the argument). Just like causal accounts of action and causal accounts of perception, causal accounts of reasoning have to confront a version of what has come to be known as the problem of deviant causal chains. In this paper, I shall propose an account of the nature of reasoning, incorporating a solution to the specific version of the deviant causal chains problem that arises for accounts of reasoning. One striking feature of my solution is that it requires that certain normative facts are causally efficacious. It might be thought that this feature will make my account incompatible with any plausibly naturalistic approach to understanding the mind. I shall argue that this is not so: my account of the nature of reasoning is quite compatible with plausible versions of naturalism.

In this paper, I explore how to accommodate non-consequentialist constraints with a broadly value-based conception of reasons for action. It turns out that there are two grades of non-consequentialist constraints. The first grade involves attaching ethical importance to such distinctions as the doing/allowing distinction, and the distinction between intended and unintended consequences that is central to the Doctrine of Double Effect. However, at least within the value-based framework, this first grade is insufficient to explain rights, which ground weighty reasons against infringing those rights that need not be outweighed even when infringing those rights is necessary for preventing a larger number of people from having their rights infringed in the same way. Such rights form a second grade of non-consequentialist constraints: within the value-based framework, this second grade is best explained in terms of the intrinsically relational values and disvalues of interpersonal interactions and relationships.

This essay defends a version of the Doctrine of Double Effect (DDE) – the doctrine that there is normally a stronger reason against an act that has a bad state of affairs as one of its intended effects than against an otherwise similar act that has that bad state of affairs as an unintended effect. First, a precise account of this version of the DDE is given. Secondly, some suggestions are made about why we should believe the DDE, and about why it is true. Finally, a solution is developed to the so-called ‘closeness problem’ that any version of the DDE must face
