David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

Epistemic contextualism is a recent and hotly debated position. In its dominant form, EC is the view that the proposition expressed by a given knowledge sentence depends upon the context in which it is uttered. What makes this view interesting and controversial is that ‘context’ here refers, not to certain features of the putative subject of knowledge or his/her objective situation, but rather to features of the knowledge attributor' psychology and/or conversational-practical situation. As a result of such context-dependence, utterances of (...) a given such sentence, made in different contexts, may differ in truth value. (shrink)

This is a selection of essays on moral responsibility that represent the major components of John Martin Fischer's overall approach to freedom of the will and moral responsibility. The collection exhibits the overall structure of Fischer's view and shows how the various elements fit together to form a comprehensive framework for analyzing free will and moral responsibility. The topics include deliberation and practical reasoning, freedom of the will, freedom of action, various notions of control, and moral accountability. The essays seek (...) to provide a foundation for our practices of holding each other (and ourselves) morally and legally accountable for our behavior. A crucial move is the distinction between two kinds of control. According to Fischer, "regulative control" involves freedom to choose and do otherwise ("alternative possibilities"), whereas "guidance control" does not. Fischer contends that guidance control is all the freedom we need to be morally responsible agents. Further, he contends that such control is fully compatible with causal determinism. Additionally, Fischer argues that we do not need genuine access to alternative possibilities in order for there to be a legitimate point to practical reasoning. Fischer's overall framework contains an argument for the contention that guidance control, and not regulative control, is associated with moral responsibility, a sketch of a comprehensive theory of moral responsibility (that ties together responsibility for actions, omissions, consequences, and character), and an account of the value of moral responsibility. On this account, the value of exhibiting freedom (of the relevant sort) and thus being morally responsible for one's behavior is a species of the value of artistic self-expression. (shrink)

The shortest form of the Basic Argument against free will and moral responsibility runs as follows: [1] When you act, you do what you do—in the situation in which you find yourself—because of the way you are. [2] If you do what you do because of the way you are, then in order to be fully and ultimately responsible for what you do you must be fully and ultimately responsible for the way you are. But [3] You cannot be fully (...) and ultimately responsible for the way you are. So [4] You cannot be fully and ultimately responsible for what you do. This paper restates the Basic Argument and varies it in several different ways. (shrink)

This article distinguishes Wittgensteinian contextualism from epistemic relativism. The latter involves the view that a belief ’s status as justified depends on the believer’s epistemic system, as well as the view that no system is superior to another. It emerges from the thought that we must rely, circularly, on our epistemic system to determine whether any belief is justified. Contextualism, by contrast, emerges from the thought that we need not answer a skeptical challenge to a belief unless there is good (...) reason to doubt the belief; so we need not rely on our epistemic system to determine whether a belief is justified. Accordingly contextualism is not committed to the view that a belief ’s status depends on the believer’s epistemic system, nor to the view that no system is superior to another. The contextualist is not committed to epistemic relativism. (shrink)

Contextualist accounts of free will recently proposed by Hawthorne and Rieber imply that the same action can be both free and unfree (depending on the attributor's context). This paradoxical consequence can be avoided by thinking of contexts not as constituted by arbitrary moves in a conversation, but rather by (relatively stable) social practices (such as the practices of attributing responsibility or of giving scientific explanations). The following two conditions are suggested as each necessary and jointly sufficient for free will: (i) (...) the agent is able to form considered practical judgements and to act accordingly, and (ii) the agent (or some agent‐involving event) is the original cause of her actions. A contextualist reformulation of the second condition is developed according to which only contexts in which responsibility is attributed are relevant for the kind of original causation required for free will, which allows for a non‐relativist contextualism about free will.

I want to discuss an approach to knowledge that I shall call simple conversational contextualism or SCC for short. Proponents of SCC think that it offers an illuminating account of both why scepti- cism is wrong and why arguments for scepticism are so intuitively appealing. I have my doubts.

"This is an important book, and no one interested in issues which touch on the free will will want to ignore it."--Ethics. In this stimulating and thought-provoking book, the author defends the thesis that free will is incompatible with determinism. He disputes the view that determinism is necessary for moral responsbility. Finding no good reason for accepting determinism, but believing moral responsiblity to be indubitable, he concludes that determinism should be rejected.

This paper proposes a contextualist solution to the puzzle about free will. It argues that the context-sensitivity of statements about freedom of the will follows from the correct analysis of these statements. Because the analysis is independently plausible, the contextualism is warranted not merely in virtue of its capacity to solve the puzzle.

A traditional concern for determinists is that the epistemic conditions an agent must satisfy to deliberate about which of a number of distinct actions to perform threaten to conflict with a belief in determinism and its evident consequences. I develop an account of the sort that specifies two epistemic requirements, an epistemic openness condition and a belief in the efficacy of deliberation, whose upshot is that someone who believes in determinism and its evident consequences can deliberate without inconsistent beliefs. I (...) argue that conditions of both types are indispensable, and that they can be formulated so as to withstand the relevant objections. (shrink)

There are powerful skeptical challenges to the idea that we are free. And yet, it seems simply impossible for us to shake the sense that we really are free. Some are convinced that the skeptical challenges are insurmountable and resign themselves to living under an illusion, while others argue that the challenges can be met. Even among those who believe that our sense of ourselves as free is at least roughly accurate, there are deep differences of opinion concerning what freedom (...) requires. On the one hand, there are “libertarians” about freedom, those who believe both that we are free and that freedom requires the falsity of determinism. On the other hand, there are “compatibilists”, those who believe that freedom is compatible with determinism. While there is an impressive variety of arguments and motivations available on all sides of the debate over freedom, our inescapable sense of ourselves as free has played a recurrent and key role in the debate, sometimes explicit and sometimes not. In this paper, I explore one way that our self-conception has been used by libertarians against compatibilists, and I argue that the reasoning employed is not convincing. The libertarian appeal to our self-conception hinges on locating in each of us an essential commitment to indeterminism, or, more cautiously, a commitment to something that, with the addition of a few plausible (if not self-evident) premises, entails indeterminism. The idea, then, is that we are “natural” indeterminists, seeing our actions as undetermined (or, again, more cautiously, as having qualities that, upon reflection, we can recognize entail the falsity of determinism). By itself, this is not an argument to the effect that we are correct in 1 believing that our actions are undetermined, or to the effect that freedom requires indeterminism. But if we are in fact natural indeterminists when it comes to our own actions, then that fact serves as important motivation for libertarianism, especially if our supposed natural indeterminism captures our unshakeable sense of freedom. Kant famously located our sense of freedom in our nature as rational agents, claiming that we must act under the “idea of freedom.”2 This has suggested to many that: (R) Rational deliberators, in virtue of their very nature as rational deliberators, must represent themselves as free..

In everyday life, we assume that there are degrees of blameworthiness and praiseworthiness. Yet the debate about the nature of moral responsibility often focuses on the “yes or no” question of whether indeterminism is required for moral responsibility, while questions about what accounts for more or less blameworthiness or praiseworthiness are underexplored. In this paper, I defend the idea that degrees of blameworthiness and praiseworthiness can depend in part on degrees of difficulty and degrees of sacrifice required for performing the (...) action in question. Then I turn to the question of how existing accounts of the nature of moral responsibility might be seen to accommodate these facts. In each case of prominent compatibilist and incompatibilist accounts that I consider, I argue that supplementation with added dimensions is required in order to account for facts about degrees of blameworthiness and praiseworthiness. For example, I argue that the reasons-responsiveness view of Fischer and Ravizza requires supplementation that takes us beyond even fine-grained measures of degrees of reasons-responsiveness in order to capture facts about degrees of difficulty to extend the reasons-responsiveness view by appealing to such measures). I conclude by showing that once we recognize the need for these additional parameters, we will be in a position to explain away at least some of the appeal of incompatibilist accounts of moral responsibility.

Discussions of free will have frequently centered on principles concerning ability, control, unavoidability and other practical modalities. Some assert the closure of the latter over various propositional operations and relations, for example, that the consequences of what is beyond one's control are themselves beyond one's control.1 This principle has been featured in the unavoidability argument for incompatibilism: if everything we do is determined by factors which are not under our control, then, by the principle, we are unable to act and (...) choose other than we actually did. A second family of principles concerns the fixity of the past and the laws of nature. If no one is able to alter the past or violate the laws it seems but a small step to conclude that no one can do anything such that if they did it then the past would be altered or the laws violated. Accordingly, if an agent's performing an act is necessitated by the past and laws, then the agent is unable to refrain from that act at that time. Generalizing, determinism precludes anyone from doing anything other than what he or she did.2. (shrink)

By deliberation we understand practical reasoning with an end in view of choosing some course of action. Integral to it is the agent's sense of alternative possibilities, that is, of two or more courses of action he presumes are open for him to undertake or not. Such acts may not actually be open in the sense that the deliberator would do them were he to so intend, but it is evident that he assumes each to be so. One deliberates only (...) by taking it for granted that both performing and refraining from any of the acts under consideration are possible for one, and that which is to be selected is something entirely up to oneself. What is it for a course of action to be presumed as open, or for several courses of action to present themselves as a range of open alternatives? Answering these questions is essential for an understanding of deliberation and choice and, indeed, for the entire issue of free will and responsibility. According to one common view, a deliberator takes the considered options to be open only by assuming he is free to undertake any of them and, consequently, that whichever he does undertake is, as yet, a wholly undetermined matter. Built into the structure of deliberation, on this theory, is an indeterministic bias relative to which any deliberator with deterministic beliefs is either inconsistent or condemned to a fatalistic limbo. An unmistakable challenge is thereby posed: is there an alternative conception of the presuppositions underlying deliberation more congenial to a deterministic perspective yet adequate to the data? Convinced that there is, I develop a partial account of deliberation that, though highly similar to the aforementioned view, diverges at a critical juncture. (shrink)

David Lewis has recently deployed a contextualist strategy for defending ordinary claims to know.1 In this paper, I wish to extend that strategy to ordinary claims about freedom.2 The result is a species of compatibilism that, while foreign to current debates, has a good deal going for it.

Derk Pereboom articulates and defends an original, forward-looking conception of moral responsibility. He argues that although we may not possess the kind of free will that is normally considered necessary for moral responsibility, this does not jeopardize our sense of ourselves as agents, or a robust sense of achievement and meaning in life.

Most people assume that, even though some degenerative or criminal behavior may be caused by influences beyond our control, ordinary human actions are not similarly generated, but rather are freely chosen, and we can be praiseworthy or blameworthy for them. A less popular and more radical claim is that factors beyond our control produce all of the actions we perform. It is this hard determinist stance that Derk Pereboom articulates in Living Without Free Will. Pereboom argues that our best scientific (...) theories have the consequence that factors beyond our control produce all of the actions we perform, and that because of this, we are not morally responsible for any of them. He seeks to defend the view that morality, meaning and value remain intact even if we are not morally responsible, and furthermore, that adopting this perspective would provide significant benefit for our lives.

The doyen of living English philosophers, by these reflections, took hold of and changed the outlook of a good many other philosophers, if not quite enough. He did so, essentially, by assuming that talk of freedom and responsibility is talk not of facts or truths, in a certain sense, but of our attitudes. His more explicit concern was to look again at the question of whether determinism and freedom are consistent with one another -- by shifting attention to certain personal (...) rather than moral attitudes, first of all gratitude and resentment. In the end, he arrived at a kind of Compatibilist or, as he says, Optimist conclusion. That is no doubt a recommendation but not the largest recommendation of this splendidly rich piece of philosophy. (shrink)
