(1996). “A real curiosity”: Charles Darwin reflects on a communication from Rabbi Naphtali Levy. The European Legacy: Vol. 1, Science and Religion in Modern Western Thought, pp. 1716-1727.

The year 2009 marked the bicentennial of Charles Darwin's birth and the 150th anniversary of the publication of The Origin of Species. From 1840 to his death in 1882, Darwin was constantly plagued by chronic illnesses that allowed him to work only a few hours at a time and by an obsession with his physical health. Was this the psychosomatic product of stress resulting from the development and public reception to his theory of evolution or the result of a disease (...) or parasite obtained during the world traveler's excursions? In 1977, the author of this volume argued persuasively for the former explanation in his book To Be an Invalid: The Illness of Charles Darwin, now out of print, but considered to be one of the century's most important works on Darwin's life. Expanding and reworking his earlier arguments to take into account new information, this book paints a more intimate portrait of the nature and possible causes of Darwin's lifelong illness, of the ways he and Victorian physicians tried treating it, and how it influenced his scientific work and relations with his family and friends.

Here is a definition of knowledge: for you to know a proposition p is for you to have an outright belief in p that is correct precisely because it manifests the virtue of rationality. This definition resembles Ernest Sosa’s “virtue theory”, except that on this definition, the only virtue that must be manifested in all instances of knowledge is rationality, and no reductive account of rationality is attempted—rationality is assumed to be an irreducibly normative notion. This definition is compatible with (...) “internalism” about rationality, and with a form of “pragmatic encroachment” on the conditions of rational outright belief. An interpretation is given of this definition, and especially of the sense of ’because’ that it involves. On this interpretation, this definition entails that both safety and adherence are necessary conditions on knowledge; it supports a kind of contextualism about terms like ‘knowledge’; and it provides resources to defend safety, adherence, and contextualism, against some recent objections.

In this paper, I apply the "conceptual role semantics" approach that I have proposed elsewhere (according to which the meaning of normative terms is given by their role in practical reasoning or deliberation) to the meaning of the term 'ought'. I argue that this approach can do three things: It can give an adequate explanation of the special connection that normative judgments have to practical reasoning and motivation for action. It can give an adequate account of why the central principles (...) of deontic logic are correct. It can give an explanation of the precise ways in which the term 'ought' is systematically context-sensitive, so that the term expresses different (but systematically related) concepts in different contexts.

Often, when one faces a choice between alternative actions, there are reasons both for and against each alternative. On one way of understanding these words, what one “ought to do all things considered (ATC)” is determined by the totality of these reasons. So, these reasons can somehow be “combined” or “aggregated” to yield an ATC verdict on these alternatives. First, various assumptions about this sort of aggregation of reasons are articulated. Then it is shown that these assumptions allow for the (...) proof of a “Reasons Aggregation Theorem” – parallel to John Harsanyi’s 1955 “Social Aggregation Theorem”. All reasons for action are grounded in reason-providing values; and, for every such reason-providing value, there is in principle a way of measuring how strongly this value counts against each alternative. The theorem tells us that the appropriate measure of how much reason ATC there is against each alternative is simply a weighted sum of the strengths with which these values count against that alternative; the agent ought not ATC to perform an action iff there is ATC more reason against it than against some available alternative.

Let us take an example that Bernard Williams (1981: 102) made famous. Suppose that you want a gin and tonic, and you believe that the stuff in front of you is gin. In fact, however, the stuff is not gin but petrol. So if you drink the stuff (even mixed with tonic), it will be decidedly unpleasant, to say the least. Should you choose to drink the stuff or not?

This essay offers an account of the truth conditions of sentences involving deontic modals like ‘ought’, designed to capture the difference between objective and subjective kinds of ‘ought’ This account resembles the classical semantics for deontic logic: according to this account, these truths conditions involve a function from the world of evaluation to a domain of worlds (equivalent to a so-called “modal base”), and an ordering of the worlds in such domains; this ordering of the worlds itself arises from two (...) further elements – a probability function and a value function – since this ordering ranks the worlds in accordance with the expected value of certain propositions that are true at those worlds. Thus, a proposition of the form ‘Ought (p)’ is true at a world of evaluation w if and only if p is true at all the top-ranked worlds in the domain assigned to w. This domain of worlds consists of metaphysically possible worlds, while the probability function is defined over a space of epistemically possible worlds (which may include metaphysically impossible worlds, such as worlds where Hesperus is not Phosphorus). Evidence is given that this account assigns the correct truth conditions to a wide range of sentences involving ‘ought’. Since these truth conditions involve both a domain of metaphysically possible worlds and a space of epistemically possible worlds, there are two corresponding kinds of conditional involving ‘ought’, depending on which space of worlds is restricted by the conditional. Finally, some objections that might be raised against this account are answered. (shrink)

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. (shrink)

Richard Price’s moral epistemology provides a distinctive account, not only of the sources of our moral knowledge, but also of its limits – that is, of the moral truths that we do not and even cannot know. According to this moral epistemology, the fundamental moral truths are necessary rather than contingent; if they are knowable at all, they are knowable a priori. In general, fundamental moral truths are akin to mathematical truths. Specifically, these necessary moral truths are grounded in the (...) essences of act-types, which are knowable through ‘intuition’ if knowable at all. However, Price firmly rejects utilitarianism, recognizing several different ‘branches of virtue’, which can conflict with each other. As he argues, we cannot know the truth about act-types that exemplify such conflicting branches of virtue if the competing considerations are too finely balanced. This view of moral epistemology is compared with those of several other philosophers, including W. D. Ross. It is argued that Price has a more unified view than Ross: for Price, all moral knowledge flows from a priori intuition, but this is compatible with our being ignorant of many of the fine details of the fundamental truths of morality.

This chapter is concerned with the distinction that most contemporary epistemologists express by distinguishing between “propositional” and “doxastic” justification. The goal is to develop an account of this distinction that applies, not just to full or outright beliefs, but also to partial credences—and indeed, in principle, to attitudes of all kinds. The standard way of explaining this distinction, in terms of the “basing relation”, is criticized, and an alternative account—the “virtue manifestation” account—is proposed in its place. This account has a (...) certain kinship with the epistemological approach that is known as “reliabilism”, but it also has certain key differences—above all, it is compatible with an internalist view of rationality.

What reasons for action do we have? What explains why we have these reasons? This paper articulates some of the basic structural features of a theory that would provide answers to these questions. According to this theory, reasons for action are all grounded in intrinsic values, but in a way that makes room for a thoroughly non-consequentialist view of the way in which intrinsic values generate reasons for aaction.

Many philosophers have claimed that the intentional is normative. (This claim is the analogue, within the philosophy of mind, of the claim that is often made within the philosophy of language, that meaning is normative.) But what exactly does this claim mean? And what reason is there for believing it? In this paper, I shall first try to clarify the content of the claim that the intentional is normative. Then I shall examine a number of the arguments that philosophers have (...) advanced for this claim (and for the parallel claim that meaning is normative). As we shall see, many of these arguments are unsuccessful. However, I shall close by giving a sketch of what may be a successful argument for this claim. (shrink)

Hierocles, a Stoic of the second century CE, famously deployed an image of the ‘concentric circles’ that surround each of us. The image should not be read as advocating absolute impartiality (in the style of classical utilitarianism) or as illustrating the Stoic theory of oikeiōsis. Instead, it is designed to illustrate how it is ‘appropriate to act’ in certain cases. Like other Stoics, Hierocles bases his investigation of appropriate acts on what is ‘in accordance with nature’. According to his view, (...) each of us has a duty of mutual aid towards every other human being—but a weightier duty towards those who are socially closer than those who are more distant. The fundamental principle is that each of us has the duty of being an ‘ally’ of every other human being in serving the natural purposes of all the circles to which we and that other human being both belong.

Substance The term “substance” has two main uses in philosophy. Both originate in what is arguably the most influential work of philosophy ever written, Aristotle’s Categories. In its first sense, “substance” refers to those things that are object-like, rather that property-like. For example, an elephant is a substance in this sense, whereas the height or … Continue reading Substance →.

Most approaches to animal ethics ground the moral standing of nonhumans in some appeal to their capacities for intelligent autonomy or mental sentience. _Corporal Compassion _emphasizes the phenomenal and somatic commonality of living beings; a philosophy of body that seeks to displace any notion of anthropomorphic empathy in viewing the moral experiences of nonhuman living beings. Ralph R. Acampora employs phenomenology, hermeneutics, existentialism and deconstruction to connect and contest analytic treatments of animal rights and liberation theory. In doing so, (...) he focuses on issues of being and value, and posits a felt nexus of bodily being, termed symphysis, to devise an interspecies ethos. Acampora uses this broad-based bioethic to engage in dialogue with other strains of environmental ethics and ecophilosophy. _Corporal Compassion_ examines the practical applications of the somatic ethos in contexts such as laboratory experimentation and zoological exhibition, and challenges practitioners to go beyond recent reforms and look to a future beyond exploitation or total noninterference--a posthumanist culture that advocates caring in a participatory approach.

Ralph Cudworth (1617-1688) deserves recognition as one of the most important English seventeenth-century philosophers after Hobbes and Locke. In opposition to Hobbes, Cudworth proposes an innatist theory of knowledge which may be contrasted with the empirical position of his younger contemporary Locke, and in moral philosophy he anticipates the ethical rationalists of the eighteenth century. A Treatise Concerning Eternal and Immutable Morality is his most important work, and this volume makes it available, together with his shorter Treatise of Freewill, (...) in its first modern edition, with a historical introduction, a chronology of his life, and an essay on further reading.
