What is required for something to be evidence for a hypothesis? In this fascinating, elegantly written work, distinguished philosopher of science Peter Achinstein explores this question, rejecting typical philosophical and statistical theories of evidence. He claims these theories are much too weak to give scientists what they want--a good reason to believe--and, in some cases, they furnish concepts that mistakenly make all evidential claims a priori. Achinstein introduces four concepts of evidence, defines three of them by reference to "potential" evidence, (...) and characterizes the latter using a novel epistemic interpretation of probability. The resulting theory is then applied to philosophical and historical issues. Solutions are provided to the "grue," "ravens," "lottery," and "old-evidence" paradoxes, and to a series of questions. These include whether explanations or predictions furnish more evidential weight, whether individual hypotheses or entire theoretical systems can receive evidential support, what counts as a scientific discovery, and what sort of evidence is required for it. The historical questions include whether Jean Perrin had non-circular evidence for the existence of molecules, what type of evidence J. J. Thomson offered for the existence of the electron, and whether, as is usually supposed, he really discovered the electron. Achinstein proposes answers in terms of the concepts of evidence introduced. As the premier book in the fabulous new series Oxford Studies in Philosophy of Science, this volume is essential for philosophers of science and historians of science, as well as for statisticians, scientists with philosophical interests, and anyone curious about scientific reasoning.

This is a book about normativity -- where the central normative terms are words like 'ought' and 'should' and their equivalents in other languages. It has three parts: The first part is about the semantics of normative discourse: what it means to talk about what ought to be the case. The second part is about the metaphysics of normative properties and relations: what is the nature of those properties and relations whose pattern of instantiation makes propositions about what ought to (...) be the case true. The third part is about the epistemology of normative beliefs: how we could ever know, or even have rational or justified belief in, propositions about what ought to be the case. (shrink)

[David Papineau] This paper disputes the common assumption that the normativity of conceptual judgement poses a problem for naturalism. My overall strategy is to argue that norms of judgement derive from moral or personal values, particularly when such values are attached to the end of truth. While there are philosophical problems associated with both moral and personal values, they are not special to the realm of judgement, nor peculiar to naturalist philosophies. This approach to the normativity of judgement is made (...) possible by naturalist views of truth, that is, views which do not presuppose normativity in explaining truth. /// [Julia Tanney] This paper attempts to describe why it is not possible to account for normative phenomena in non-normative terms. It argues that Papineau's attempt to locate norms of judgement 'outside' content, grounded in an individual's desires or reasons, mislocates the normativity that is thought to resist appropriation within a 'world that conceives nature as the realm of law'. It agrees, however, that a theory of content that locates norms 'inside' content will not be forthcoming-at least if this is to require fashioning the norms that in some sense govern judgment or thought into individually necessary conditions for contentful states.

Humean promotionalists about reasons think that whether there is a reason for an agent to ϕ depends on whether her ϕ-ing promotes the satisfaction of at least one of her desires. Several authors have recently defended probabilistic accounts of promotion, according to which an agent’s ϕ-ing promotes the satisfaction of one of her desires just in case her ϕ-ing makes the satisfaction of that desire more probable relative to some baseline. In this paper I do three things. First, I formalize (...) an argument, due to Jeff Behrends and Joshua DiPaolo, to the effect that Mark Schroeder’s and Stephen Finlay’s probabilistic accounts of promotion cannot be correct. Next, I extend this argument to a recent alternative offered by D. Justin Coates and show how Coates’ attempt to avoid the argument by introducing a distinction between ‘intrinsic’ and ‘extrinsic’ probability doesn’t help. Finally, I suggest an alternative way of understanding promotion in terms of increase in degree of fit between the causal upshot of an action and the content of a desire. I show how this view, disjunctively paired with probabilism about promotion, solves the problems with previous accounts. (shrink)

This paper has two goals. First, I offer an interpretation of Nietzsche’s puzzling claims about will to power. I argue that the will to power thesis is a version of constitutivism. Constitutivism is the view that we can derive substantive normative conclusions from an account of the nature of agency; in particular, constitutivism rests on the idea that all actions are motivated by a common, higher-order aim, whose presence generates a standard of assessment for actions. Nietzsche’s version of constitutivism is (...) based on a series of subtle claims about the psychology of willing and the nature of satisfaction, which imply that all actions aim at encountering and overcoming resistance (this is what Nietzsche means by “will to power”). Second, I argue that Nietzsche’s theory, thus interpreted, generates a new, a posteriori version of constitutivism that is not vulnerable to certain familiar objections. If this is right, then we can deploy Nietzschean ideas in order to make a substantive contribution to issues that are currently at the forefront of ethics and action theory. (shrink)

Relativism offers a nifty way of accommodating most of our intuitions about epistemic modals, predicates of personal taste, color expressions, future contingents, and conditionals. But in spite of its manifest merits relativism is squarely at odds with epistemic value monism: the view that truth is the highest epistemic goal. I will call the argument from relativism to epistemic value pluralism the trivial argument for epistemic value pluralism. After formulating the argument, I will look at three possible ways to refute it. (...) I will then argue that two of these are unsuccessful, and defend the third, which involves denying that there are any genuinely relative truths. (shrink)

Many believe that normative reasons for action are necessarily connected with the promotion of certain states of affairs: on Humean views, for example, there is a reason for you to do something if and only if it would promote the object of one of your desires. But although promotion is widely invoked in discussions of reasons, its nature is a matter of controversy. I propose a simple account: to promote a state of affairs is to make it more likely to (...) obtain than it previously was. I argue that this view has been unfairly neglected, that it avoids serious problems faced by many other views, and that it is a contender for the correct theory of promotion. (shrink)

Does transparency in doxastic deliberation entail a constitutive norm of correctness governing belief, as Shah and Velleman argue? No, because this presupposes an implausibly strong relation between normative judgements and motivation from such judgements, ignores our interest in truth, and cannot explain why we pay different attention to how much justification we have for our beliefs in different contexts. An alternative account of transparency is available: transparency can be explained by the aim one necessarily adopts in deliberating about whether to (...) believe that p. To show this, I reconsider the role of the concept of belief in doxastic deliberation, and I defuse 'the teleologian's dilemma'. (shrink)

This paper argues against two prominent accounts of what it is to "promote a desire," found in the work of Stephen Finlay and Mark Schroeder.
