Is imagination too liberal for modal epistemology?

Appealing to imagination for modal justification is very common. But not everyone thinks that all imaginings provide modal justification. Recently, Gregory and Kung :620–663, 2010) have independently argued that, whereas imaginings with sensory imageries can justify modal beliefs, those without sensory imageries don’t because of such imaginings’ extreme liberty. In this essay, I defend the general modal epistemological relevance of imagining. I argue, first, that when the objections that target the liberal nature of non-sensory imaginings are adequately developed, those objections also threaten the sensory imaginings. So, if we think that non-sensory imaginings are too liberal for modal justification, we should say the same about sensory imaginings. I’ll finish my defense by showing that, when it comes to deciding between saying that all imaginings are prima facie justificatory and saying that no imaginings are justificatory, there is an independent reason for accepting the former

Thick Concepts

A term expresses a thick concept if it expresses a specific evaluative concept that is also substantially descriptive. It is a matter of debate how this rough account should be unpacked, but examples can help to convey the basic idea. Thick concepts are often illustrated with virtue concepts like courageous and generous, action concepts like murder and betray, epistemic concepts like dogmatic and wise, and aesthetic concepts like gaudy and brilliant. These concepts seem to be evaluative, unlike purely descriptive concepts such as red and water. But they also seem different from general evaluative concepts. In particular, thick concepts are typically contrasted with thin concepts like good, wrong, permissible, and ought, which are general evaluative concepts that do not seem substantially descriptive. When Jane says that Max is good, she appears to be evaluating him without providing much description, if any. Thick concepts, on the other hand, are evaluative and substantially descriptive at the same time. For instance, when Max says that Jane is courageous, he seems to be doing two things: evaluating her positively and describing her as willing to face risk. Because of their descriptiveness, thick concepts are especially good candidates for evaluative concepts that pick out properties in the world. Thus they provide an avenue for thinking about ethical claims as being about the world in the same way as descriptive claims. Thick concepts became a focal point in ethics during the second half of the twentieth century. At that time, discussions of thick concepts began to emerge in response to certain disagreements about thin concepts. For example, in twentieth-century ethics, consequentialists and deontologists hotly debated various accounts of good and right. It was also claimed by non-cognitivists and error-theorists that these thin concepts do not correspond to any properties in the world. Dissatisfaction with these viewpoints prompted many ethicists to consider the implications of thick concepts. The notion of a thick concept was thought to provide insight into meta-ethical questions such as whether there is a fact-value distinction, whether there are ethical truths, and, if there are such truths, whether these truths are objective. Some ethicists also theorized about the role that thick concepts can play in normative ethics, such as in virtue theory. By the beginning of the twenty-first century, the interest in thick concepts had spread to other philosophical disciplines such as epistemology, aesthetics, metaphysics, moral psychology, and the philosophy of law. Nevertheless, the emerging interest in thick concepts has sparked debates over many questions: How exactly are thick concepts evaluative? How do they combine evaluation and description? How are thick concepts related to thin concepts? And do thick concepts have the sort of significance commonly attributed to them? This article surveys various attempts at answering these questions

Brains In Vats? Don\u27t Bother!

Contemporary discussions of epistemological skepticism – the view that we do not and cannot know anything about the world around us – focus very much on a certain kind of skeptical argument involving a skeptical scenario (a situation familiar from Descartes\u27 First Meditation). According to the argument, knowing some ordinary proposition about the world (one we usually take ourselves to know) requires knowing we are not in some such skeptical scenario SK; however, since we cannot know that we are not in SK we also cannot know any ordinary proposition. One of the most prominent skeptical scenarios is the brain-in-the-vat-scenario: An evil scientist has operated on an unsuspecting subject, removed the subject\u27s brain and put it in a vat where it is kept functioning and is connected to some computer which feeds the brain the illusion that everything is “normal”. This paper looks at one aspect of this scenario after another – envatment, disembodiment, weird cognitive processes, lack of the right kind of epistemic standing, and systematic deception. The conclusion is that none of these aspects (in isolation or in combination) is of any relevance for a would-be skeptical argument; the brain-in-the-vat-scenario is irrelevant to and useless for skeptical purposes. Given that related scenarios (e.g., involving evil demons) share the defects of the brain-in-the-vat-scenario, the skeptic should not put any hopes on Cartesian topoi

Disqualifying ‘Disqualifiers’

In addition to the notion of defeat, do we need to expand the epistemological repertoire used in accounting for the context dependence of justification? It has recently been argued that we ought to admit a hitherto unrecognized fundamental epistemic kind called ‘disqualifiers’. Disqualifiers are taken to be not reducible to any other epistemic notion. Rather, they are meant to be primitive. If this is correct, it is a surprising and novel discovery, and so it is worthy of further epistemological investigation. In this paper I shall first argue that the cases given do not motivate positing the notion of a disqualifier. Conclusions drawn about the existence of disqualifiers do not follow from the considerations advanced. Second, I shall directly argue that an essential core claim of those who would posit disqualifiers, that so-called disqualifiers actually do prevent epistemic bases from conferring justification, is false. In sum, I shall argue that there are no disqualifiers

Intuitive Evidence and Experimental Philosophy

In recent years, some defenders of traditional philosophical methodology have argued that certain critiques of armchair methods are mistaken in assuming that intuitions play central evidential roles in traditional philosophical methods. According to this kind of response, experimental philosophers attack a straw man; it doesn’t matter whether intuitions are reliable, because philosophers don’t use intuitions in the way assumed. Deutsch (2010), Williamson (2007), and Cappelen (2012) all defend traditional methods in something like this way. I also endorsed something like this line in Ichikawa (2014a). In this contribution, I will follow up on this sort of defence of traditional philosophical methods in three ways. In §1, I will rehearse and extend some of my reasons for challenging the idea that traditional methods depend on intuitions in an evidential role. (My reasons are very different from those discussed in (Cappelen, 2012).) I will also engage with some recent more sophisticated attempts to establish the idea that intuitions play evidential roles in philosophy, such as that of Chudnoff (2013). In §2, I will consider and argue against a dismissive response to such positions from experimental philosophers, who consider the question of philosophical reliance on intuitions to be irrelevant to the experimentalist critique. But in §3, I will argue that it would also be a mistake to conclude (as Herman Cappelen does) that the critique is rendered totally irrelevant by the denial of the evidential role of intuitions; I defend a more moderate view on which the bearing of experimental studies of philosophical intuitions is relevant for philosophical methodology, but only in a relatively limited way

Truth, knowledge, and the standard of proof in criminal law

Could it be right to convict and punish defendants using only statistical evidence? In this paper, I argue that it is not and explain why it would be wrong. This is difficult to do because there is a powerful argument for thinking that we should convict and punish defendants using statistical evidence. It looks as if the relevant cases are cases of decision under risk and it seems we know what we should do in such cases (i.e., maximize expected value). Given some standard assumptions about the values at stake, the case for convicting and punishing using statistical evidence seems solid. In trying to show where this argument goes wrong, I shall argue (against Lockeans, reliabilists, and others) that beliefs supported only by statistical evidence are epistemically defective and (against Enoch, Fisher, and Spectre) that these epistemic considerations should matter to the law. To solve the puzzle about the role of statistical evidence in the law, we need to revise some commonly held assumptions about epistemic value and defend the relevance of epistemology to this practical question

The Epistemology of Anger in Argumentation

While anger can derail argumentation, it can also help arguers and audiences to reason together in argumentation. Anger can provide information about premises, biases, goals, discussants, and depth of disagreement that people might otherwise fail to recognize or prematurely dismiss. Anger can also enhance the salience of certain premises and underscore the importance of related inferences. For these reasons, we claim that anger can serve as an epistemic resource in argumentation

The Problem of Confirmation in the Everett Interpretation

I argue that the Oxford school Everett interpretation is internally incoherent, because we cannot claim that in an Everettian universe the kinds of reasoning we have used to arrive at our beliefs about quantum mechanics would lead us to form true beliefs. I show that in an Everettian context, the experimental evidence that we have available could not provide empirical confirmation for quantum mechanics, and moreover that we would not even be able to establish reference to the theoretical entities of quantum mechanics. I then consider a range of existing Everettian approaches to the probability problem and show that they do not succeed in overcoming this incoherence

Empiricism, Stances, And The Problem Of Voluntarism

Classical empiricism leads to notorious problems having to do with the (at least prima facie) lack of an acceptable empiricist justification of empiricism itself. Bas van Fraassen claims that his idea of the empirical stance can deal with such problems. I argue, however, that this view entails a very problematic form of voluntarism which comes with the threat of latent irrationality and normative inadequacy. However, there is also a certain element of truth in such a voluntarism. The main difficulty consists in finding an acceptable form of voluntarism
