Publisher’s Note: Most expressions in natural language are vague. But what is the best semantic treatment of terms like ‘heap’, ‘red’ and ‘child’? And what is the logic of arguments involving this kind of vague expression? These questions are receiving increasing philosophical attention, and in this timely book Rosanna Keefe explores the questions of what we should want from an account of vagueness and how we should assess rival theories. Her discussion ranges widely and comprehensively over the main theories of vagueness and their supporting arguments, and she offers a powerful and original defence of a form of supervaluationism, a theory that requires almost no deviation from standard logic yet can accommodate the lack of sharp boundaries to vague predicates and deal with the paradoxes of vagueness in a methodologically satisfying way. Her study will be of particular interest to readers in philosophy of language and of mind, philosophical logic, epistemology and metaphysics.
Fundamental Properties and the Laws of Nature
Abstract: Fundamental properties and the laws of nature go hand in hand: mass and gravitation, charge and electromagnetism, spin and quantum mechanics. So, it is unsurprising that one’s account of fundamental properties affects one’s view of the laws of nature and vice versa. In this essay,the author surveys a variety of recent attempts to provide a joint account of the fundamental properties and the laws of nature. Many of these accounts are new and unexplored. Some of them posit surprising entities, such as counterfacts. Other accounts posit surprising laws of nature, such as instantaneous laws that constrain the initial configuration of particles. These exciting developments challenge our assumptions about our basic ontology and provide fertile ground for further exploration.
Distinguishing Explanatory from Nonexplanatory Fictions
Abstract: There is a growing recognition that fictions have a number of legitimate functions in science, even when it comes to scientific explanation. However, the question then arises, what distinguishes an explanatory fiction from a nonexplanatory one? Here I examine two cases – one in which there is a consensus in the scientific community that the fiction is explanatory and another in which the fiction is not explanatory. I shall show how my account of “model explanations” is able to explain this asymmetry, and argue that realism – of a more subtle form – does have a role in distinguishing explanatory from nonexplanatory fictions.
White Ignorance
The development of social epistemology in recent decades is a welcome turn away from Cartesian individualism. But the centrality of oppression to societies in general is still insufficiently recognized in this literature. This chapter looks at white ignorance as an example of a particular kind of systemic group-based miscognition that has been hugely influential over the past few hundred years. After a ten-point clarification of the concept, it turns to an examination of white ignorance as it plays itself out in the complex interaction of Eurocentric perception and categorization, white normativity, social memory and social amnesia, the derogation of non-white testimony, racial group interests, and motivated irrationality.
Subject-Sensitive Invariantism and the Knowledge Norm for Practical Reasoning
Introduction: It is increasingly popular to suggest that knowledge is the norm of practical reasoning, or reasoning about what to do (e.g. Hawthorne 2004, Stanley 2005). This idea is central to the defence of a new version of invariantism – ‘subject-sensitive invariantism’ – on which whether the true belief that p is knowledge not only depends on such factors as one’s evidence, and the reliability of the belief-producing process, but also the stakes or how important it is that p be true (the view is also known as ‘sensitive moderate invariantism’ (Hawthorne 2004) and ‘interest relative invariantism’ (Stanley 2005)). I will argue against the idea that knowledge is the norm of practical reasoning, whether that is understood as a necessity or sufficiency claim. Instead, I will argue that the epistemic standards for practical reasoning vary contextually.
True Enough
Abstract: Truth is standardly considered a requirement on epistemic acceptability. But science and philosophy deploy models, idealizations and thought experiments that prescind from truth to achieve other cognitive ends. I argue that such felicitous falsehoods function as cognitively useful fictions. They are cognitively useful because they exemplify and afford epistemic access to features they share with the relevant facts. They are falsehoods in that they diverge from the facts. Nonetheless, they are true enough to serve their epistemic purposes. Theories that contain them have testable consequences, hence are factually defeasible.
Semantic Externalism and Psychological Externalism
Abstract: Externalism is widely endorsed within contemporary philosophy of mind and language. Despite this, it is far from clear how the externalist thesis should be construed and, indeed, why we should accept it. In this entry I distinguish and examine three central types of externalism: what I call foundational externalism, externalist semantics, and psychological externalism. I suggest that the most plausible version of externalism is not in fact a very radical thesis and does not have any terribly interesting implications for philosophy of mind, whereas the more radical and interesting versions of externalism are quite difficult to support.
Why We Don’t Deserve Credit for Everything We Know
Abstract: A view of knowledge – what I call the Deserving Credit View of Knowledge (DCVK) – found in much of the recent epistemological literature, particularly among so-called virtue epistemologists, centres around the thesis that knowledge is something for which a subject deserves credit. Indeed, this is said to be the central difference between those true beliefs that qualify as knowledge and those that are true merely by luck – the former, unlike the latter, are achievements of the subject and are thereby creditable to her. Moreover, it is often further noted that deserving credit is what explains the additional value that knowledge has over merely lucky true belief. In this paper, I argue that the general conception of knowledge found in the DCVK is fundamentally incorrect. In particular, I show that deserving credit cannot be what distinguishes knowledge from merely lucky true belief since knowledge is not something for which a subject always deserves credit.
Rational Authority and Social Power: Toward a Truly Social Epistemology
Abstract: This paper explores the relation between rational authority and social power, proceeding by way of a philosophical genealogy derived from Edward Craig’s Knowledge and the State of Nature. The position advocated avoids the errors both of the ‘traditionalist’ (who regards the socio-political as irrelevant to epistemology) and of the ‘reductivist’ (who regards reason as just another form of social power). The argument is that a norm of credibility governs epistemic practice in the state of nature, which, when socially manifested, is likely to imitate the structures of social power. A phenomenon of epistemic injustice is explained, and the politicizing implication for epistemology educed.
Intentions and the Reasons for Which we Act
Abstract: Many of the things we do in the course of a day we don’t do intentionally: blushing, sneezing, breathing, blinking, smiling – to name but a few. But we also do act intentionally, and often when we do we act for reasons. Whether we always act for reasons when we act intentionally is controversial. But at least the converse is generally accepted: when we act for reasons we always act intentionally. Necessarily, it seems. In this paper, I argue that acting intentionally is not in all cases acting for a reason. Instead, intentional agency involves a specific kind of control. Having this kind of control makes it possible to modify one’s action in the light of reasons. Intentional agency opens the possibility of acting in the light of reasons. I also explain why when we act with an intention we act for reasons. In the second part of the paper, I draw on these results to show that the dominant view of reasons to intend and the rationality of intentions should be rejected.
