Suppose that disgust can provide evidence of moral wrongdoing. What account of disgust might make sense of this? A recent and promising theory is the social contagion view, proposed by Alexandra Plakias. After criticizing both its descriptive and normative claims, I draw two conclusions. First, we should question the wisdom of drawing so straight a line from biological poisons and pathogens to social counterparts. Second, we don’t need to explain the evidential value of disgust by appealing to what the response (...) tracks. These lessons point toward an alternative: namely, that disgust is a moral heuristic. On the heuristic view, disgust is a trigger for the subconscious use of a particular rule: I show how this view fits with a plausible hypothesis about the social function of disgust, and then apply it to Leon Kass’s famous use of repugnance to criticize cloning.

Accounts of modal knowledge are many and varied. How should we choose between them? I propose that we employ inference to the best explanation, and I suggest that there are three desiderata that we should use to rank hypotheses: conservatism, simplicity, and the ability to handle disagreement. After examining these desiderata, I contend that they can’t be used to justify belief in the modal epistemology that fares best, but that they can justify our accepting it in an epistemically significant sense. (...) Finally, I outline a modal epistemology that seems to do well by the standards I’ve recommended. (shrink)

At many slaughterhouses, if a pregnant cow is killed, then medical companies pay to harvest the fetus's blood. When you communicate the details of this process to people, many of them are disgusted. I submit that those who are repulsed thereby acquire a reason to believe that this practice is morally wrong. However, it is controversial to maintain that disgust can provide moral guidance. So, I develop a theory of disgust’s moral salience that fits with the empirical work that’s been (...) done on it, and I apply it to the collection of bovine fetal blood. I conclude by suggesting how this theory may be of use in animal ethics generally. (shrink)

A potential explanation of a fact is a hypothesis such that, if it were true, it would explain the fact in question. Let’s suppose that we become aware of a fact and some potential explanations thereof. Let’s also suppose that we would like to believe the truth. Given this aim, we can ask two questions. First, is it likely that one of these hypotheses is true? Second, given an affirmative answer to the first question, which one is it likely to (...) be? Inference to the best explanation (IBE) offers answers to both questions. To the first, it says ‘Yes’—assuming that at least one of the hypotheses would, if true, provide a satisfactory explanation of the fact under consideration. To the second, it says that the hypothesis most likely to be true is the one that scores best on the explanatory virtues: conservatism, modesty, simplicity, generality, and predictive power. Many philosophers have argued against IBE’s answer to the first question. I am interested in an objection to its answer to the second. Many philosophers seem to think that it is unsustainable: they seem to think that even if we assume that one of the competing hypotheses is true, we should not think that IBE will help us to identify it. Or, more carefully, if these philosophers are doing what they appear to be doing—namely, offering critiques of IBE that don’t depend on assumptions about the field of competing hypotheses—then their claim is that IBE will not help us to identify the truth. I believe that this is mistaken: the argument for believing it assumes a model of IBE that we have no reason to accept. (shrink)

Some philosophers think that a person can justifi ably believe that p is possible even though she has no theory according to which p is possible. They think, for example, that she can justifiably believe that there could be naturally purple elephants even though she lacks (inter alia) a theory about the factors germane to elephant pigmentation. There is a certain optimism about this view: it seems to assume that people are fairly good at ferreting out problems with proposed modal (...) claims; so, if a person doesn’t detect one, then she’s within her rights to assume that there is no problem to be found. I am suspicious of this optimism, but I do not have space to challenge it here. Instead, I want to outline the more pessimistic alternative. Suppose that a person is not justified in believing that p is possible unless she has a theory according to which p is possible. How might such an account be developed? My aim is to map out this neglected option. (shrink)

Meat-eating has been the norm in most human societies. Historically, it has not had many defenders, but this is probably because few thought that it was in need of defense. In the contemporary philosophical literature, however, the pro-vegetarian arguments are usually taken to be quite strong, and omnivores have assumed the burden of proof. The purpose of this entry is to explain this shift by surveying the various frameworks that offer neutral or positive moral assessments of meat-eating. After briefly tracing (...) the evolution of these frameworks from the ancient to modern period, the entry outlines the three most prominent contemporary approaches. It closes by considering possibilities for future research. (shrink)

I contend that there are strong moral reasons for most adult family members to avoid having sex with one another; indeed, I argue that even among consenting adults, incestuous sex is usually wrong. The argument is simple. Absent compelling reasons, it's wrong to take a significant risk with something that's extremely valuable. But having sex with a family member takes a significant risk with something extremely valuable—namely, a family relationship. And since compelling reasons for taking such a risk are very (...) hard to come by, it follows that incest is usually wrong. (shrink)

We aren’t particularly sympathetic to modal realism (MR). Still, it isn’t clear to us that David Lewis argues for it in the wrong way. “The hypothesis is serviceable,” he says, “and that is a reason to think that it is true” (1986, p. 3). Let’s grant him the first claim: MR is serviceable, which is to say that it allows us “to reduce the diversity of notions we must accept as primitive, and thereby to improve the unity and economy of (...) the theory that is our professional concern – total theory, the whole of what we take to be true” (1986, p. 4). Our interest here is in the second claim, the thesis to the effect that a hypothesis’s being serviceable can provide reason to believe it. A number of philosophers maintain that this latter is false; others insist that it’s of no help to Lewis. So on one basis or the other, they conclude that Lewis’ argument for MR doesn’t get off the ground.1 We disagree. Our aim here is to show that there isn’t a cogent objection to Lewis’ use of serviceability that doesn’t rely a premise that he is justified in rejecting. (shrink)

The articles take a decidedly interdisciplinary look at the opus of the French philosopher, sociologist and pioneer of spatial analysis Henri Lefebvre. His works are reflected upon from theoretical and practical perspectives by authors from various fields closely examining text references from Lefebvre.
