What sorts of consideration can be normative reasons for action? If we systematize the wide variety of considerations that can be cited as normative reasons, do we find that there is a single kind of consideration that can always be a reason? Desire-based theorists think that the fact that you want something or would want it under certain evaluatively neutral conditions can always be your normative reason for action. Value-based theorists, by contrast, think that what plays that role are evaluative (...) facts (or the facts that subvene them) about what you want, such as the fact that having it would be good in some way. This paper argues that value-based theorists are wrong; if we try to find a single kind of consideration that can always be normative reason, we find that sometimes our reason is the fact that we want something and not any corresponding evaluative fact.

In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other.

In the subsequent pages, I want to develop a distinction between wanting and valuing which will enable the familiar view of freedom to make sense of the notion of an unfree action. The contention will be that, in the case of actions that are unfree, the agent is unable to get what he most wants, or values, and this inability is due to his own "motivational system." In this case the obstruction to the action that he most wants to do (...) is his own will. It is in this respect that the action is unfree: the agent is obstructed in and by the very performance of the action. (shrink)

I argue that emotions are belief/desire sets characterized by strong desire.

The Aristotelian dictum that desire is the starting point of practical reasoning that ends in action can of course be denied. Its denial is a commonplace of moral theory in the tradition of Kant. But in this essay I am concerned with that issue only indirectly. I shall not contend that rational action always or necessarily does involve desire as its starting point; nor shall I deny it. My question concerns instead the possibility of its ever beginning in desire. For (...) there is a question whether it is even possible for reasoning to begin in desire, a question arising from the nature of desire and its objects, which to my knowledge has not been articulated. If we can see how desire can provide the arche of action, then we can consider later, and from that vantage point, whether it is necessary that it should do so. It will, I think, be possible eventually to argue that if practical reasoning has the character it must have, if it can begin in desire, then its starting point can be nothing but desire. (shrink)

A perfectly matched layer (PML) absorbing material composed of a uniaxial anisotropic material is presented for the truncation of finite-difference time-domain (FDTD) lattices. It is shown that the uniaxial PML material formulation is mathematically equivalent to the perfectly matched layer method published by Berenger (see J. Computat. Phys., Oct. 1994). However, unlike Berenger's technique, the uniaxial PML absorbing medium presented in this paper is based on a Maxwellian formulation. Numerical examples demonstrate that the FDTD implementation of the uniaxial PML medium (...) is stable, equal in effectiveness as compared to Berenger's PML medium, while being more computationally efficient.

According to the view we may term “strong cognitivism”, all reasons for action are rooted in normative features that the motivated subject takes objects to have independently of her attitudes towards these objects. The main concern of this paper is to argue against strong cognitivism, that is, to establish the view that conative attitudes do provide subjects with reasons for action. The central argument to this effect is a top-down argument: it proceeds by an analysis of the complex phenomenon of (...) love and derives a conclusion regarding the nature of more basic mental phenomena—particular desires. More specifically, its starting point is the crude intuition that the significance conferred by love upon its objects is of a distinctively personal kind—an intuition that is expressed by the apparent non-substitutability of two similar subjects only one of whom is loved with respect to their importance for the lover. I argue that the initial notion of non-substitutability can be refined and modified so as to form a real challenge to all versions of strong cognitivism and to establish the existence of attitude-dependent reasons.

I consider two inter-related problems in the philosophy of action. One concerns the role of the agent in the determination of action, and I call it the problem of agential authority. The other concerns the relation between motivating desire and the agent's normative deliberation, and I call it the problem of subjective normative authority. In part by way of discussion of work of Harry Frankfurt and Christine Korsgaard, I argue that we make progress with these problems by appeal to certain (...) kinds of higher-order policies and to their role in the cross-temporal organization of the deliberation and action of temporally persisting agents like us.

Joseph Raz presents a penetrating exploration of the interdependence of value, reason, and the will. These essays illuminate a wide range of questions concerning fundamental aspects of human thought and action. Engaging Reason is a summation of many years of original, compelling, and influential work by a major contemporary philosopher.

An important argument for the belief-desire thesis is based on the idea that an agent can be motivated to act only if her mental states include one which aims at changing the world, that is, one with a “world-to-mind”, or “telic”, direction of fit. Some cognitivists accept this claim, but argue that some beliefs, notably moral ones, have not only a “mind-to-world”, or “thetic”, direction of fit, but also a telic one. The paper first argues that this cognitivist reply is (...) deficient, for only the “dominant” direction of fit of an attitude is responsible for its character and function. Further, it seems that the dominant direction of fit of an attitude is determined by its psychological mode, and so all beliefs seem to have a dominant thetic direction of fit, and to be motivationally inert. The main part of this paper, however, is devoted to explaining how it is that attitudes, like moral attitudes, can truly have two directions of fit in a way which enables them to be both cognitive and motivational. Reflection on the nature of beliefs suggests that the claim that the dominant direction of fit of an attitude is determined by its psychological mode should be qualified. The reasons beliefs provide draw their authority for the agent – their demanding nature – from the objects represented by these beliefs, and so, it is the beliefs’ content which determine their dominant direction of fit, as far as their role in practical reasoning is concerned. Thus, in the sense relevant to practical reasoning a belief with a normative content does have a dominant telic direction of fit. At the same time, in the sense relevant to its satisfaction conditions a moral belief has a dominant thetic direction of fit, which underlies its classification as a cognitive attitude. Cognitivists, then, can have it both ways. (shrink)

According to strong representationalism it is in virtue of having a particular representational content that an experience has the specific phenomenal character that it has. This paper argues that representationalism does not have the resources to explain the most salient aspect of the phenomenal character of pain – it is bound to leave out the painfulness of pain or its negative affect. Its central argument proceeds by analysing the rationalising role of pains. According to it, representationalism is committed to a (...) false picture on which a subject who knowingly acts so as to get rid of her pain without thereby getting rid of the bodily condition it represents always behaves irrationally – in so acting she is shooting the messenger. Thus, there can be no viable representationalist account of the phenomenal character of pain. (shrink)
