I explore the motivation and logical consequences of the idea that we have some (limited) ability to know contingent facts about the future, even in presence of the assumption that the future is objectively unsettled or indeterminate. I start by formally characterizing skepticism about the future. This analysis nudges the anti-skeptic towards the idea that if some propositions about the future are objectively indeterminate, then it may be indeterminate whether a suitably positioned agent knows them. -/- Philosophical Perspectives, Volume 35, (...)

Some philosophers have argued that truth is a norm of judgement and have provided a variety of formulations of this general thesis. In this paper, I shall side with these philosophers and assume that truth is a norm of judgement. What I am primarily interested in here are two core questions concerning the judgement-truth norm: (i) what are the normative relationships between truth and judgement? And (ii) do these relationships vary or are they constant? I argue for a pluralist picture—what (...) I call Normative Alethic Pluralism (NAP)—according to which (i) there is more than one correct judgement-truth norm and (ii) the normative relationships between truth and judgement vary in relation to the subject matter of the judgement. By means of a comparative analysis of disagreement in three areas of the evaluative domain—refined aesthetics, basic taste and morality—I show that there is an important variability in the normative significance of disagreement—I call this the variability conjecture. By presenting a variation of Lynch’s scope problem for alethic monism, I argue that a monistic approach to the normative function of truth is unable to vindicate the conjecture. I then argue that normative alethic pluralism provides us with a promising model to account for it. (shrink)

Some philosophers writing on the possibility of faultless disagreement have argued that the only way to account for the intuition that there could be disagreements which are faultless in every sense is to accept a relativistic semantics. In this article we demonstrate that this view is mistaken by constructing an absolutist semantics for a particular domain – aesthetic discourse – which allows for the possibility of genuinely faultless disagreements. We argue that this position is an improvement over previous absolutist responses (...) to the relativist's challenge and that it presents an independently plausible account of the semantics of aesthetic discourse.

Revisionary theories of logic or truth require revisionary theories of mind. This essay outlines nonclassically based theories of rational belief, desire, and decision making, singling out the supervaluational family for special attention. To see these nonclassical theories of mind in action, this essay examines a debate between David Lewis and Derek Parfit over what matters in survival. Lewis argued that indeterminacy in personal identity allows caring about psychological connectedness and caring about personal identity to amount to the same thing. The (...) essay argues that Lewis's treatment of two of Parfit's puzzle cases—degreed survival and fission—presuppose different nonclassical treatments of belief and desire. (shrink)

Some have argued that the possibility of faultless disagreement gives relativist semantic theories an important explanatory advantage over their absolutist and contextualist rivals. Here I combat this argument, focusing on the specific case of aesthetic discourse. My argument has two stages. First, I argue that while relativists may be able to account for the possibility of faultless aesthetic disagreement, they nevertheless face difficulty in accounting for the intuitive limits of faultless disagreement. Second, I develop a new non-relativist theory which can (...) account for the full range of data regarding faultless disagreement. This view—‘Humean Absolutism’—integrates two of Hume’s central principles from Of the Standard of Taste into a truth-conditional framework, resulting in a non-bivalent theory of aesthetic truth. I argue that Humean Absolutism can underwrite the possibility of faultless disagreement whilst retaining reasonable limits around the phenomenon. I close by relating this positive account of faultless disagreement to broader issues concerning the cognitive role of truth-value gaps. -/- *NB - this is an unpublished paper and is no longer in progress.*.

The topic of this paper is whether there is metaphysical vagueness. It is shown that it is important to distinguish between the general phenomenon of indeterminacy and the more narrow phenomenon of vagueness (the phenomenon that paradigmatically rears its head in sorites reasoning). Relatedly, it is important to distinguish between metaphysical indeterminacy and metaphysical vagueness. One can wish to allow metaphysical indeterminacy but rule out metaphysical vagueness. As is discussed in the paper, central argument against metaphysical vagueness, like those of (...) Gareth Evans and Mark Sainsbury, would if successful rule out metaphysical indeterminacy. One way to argue specifically against the possibility of metaphysical vagueness might be thought to be to argue for a specific theory of the nature of vagueness according to which vagueness is a semantic phenomenon. But it is shown that there are complications also pertaining to arguments with that structure. Toward the end of the paper, I discuss Trenton Merricks’ well-known argument against a semantic view on vagueness and for a metaphysical view. (shrink)

In his recent Analysis article (2012), Robert Williams considers two puzzles relating to indeterminacy. On the basis of these puzzles, he defends a seemingly radical view on the normative role of indeterminacy. He speaks of indeterminacy as ‘normatively silent’. There are two ways of understanding the view that Williams defends. On one understanding, the view ends up being indistinguishable from one of the more traditional views Williams rejects, the view that phenomena of different kinds fall under the umbrella level ‘indeterminacy’. (...) On the other understanding, Williams’s view is genuinely radical but his arguments don't adequately support it. (shrink)

Can someone who suspends judgement about a certain proposition <p> be in a relational state of disagreement with someone who believes <p> as well as with some- one who disbelieves <p>? This paper argues for an af- firmative answer. It develops an account of the notions of suspended judgement and disagreement that explains how and why the suspender is in a relational state of disagreement with both the believer and the disbeliever about the very same proposition <p>. More specifically, the (...) paper first provides a characterisation of the norma- tive profile associated with the state of suspended judge- ment in terms of the set of normative commitments that it engenders in the context of inquiry. It then provides a characterisation of the notion of disagreement in terms the incompatibility between the sets of normative com- mitments characteristic of the three states in question— belief, disbelief, and suspension.

A prominent philosophical debate concerns whether we should accept causal decision theory or evidential decision theory as our best theory of rational choice. However, instead of accepting one of these theories at the expense of the other, an alternative would be to accept that both theories play a partial role in the true account of rational choice. In this paper, I defend a pluralist account of this sort. In particular, I argue that rational permissibility is an indeterminate notion, with EDT (...) and CDT each corresponding to one sharpening of this notion. (shrink)

I present a novel strategy to account for two thoughts concerning disagreements about taste: (i) that they need not involve any substantive fault (faultlessness); (ii) that the faultlessness of a contrary opinion can be coherently appreciated from within a committed perspective (parity). Under the assumption that judgments of taste are truth-apt and governed by the truth-norm, I argue that understanding how exactly truth is normative offers a strategy for accounting for both thoughts. I distinguish between different ways in which truth (...) governs judgment to substantiate the thesis that truth’s normative function varies according to the subject matter at issue. I then argue that truth’s normative guidance in the domain of taste is characteristically weak. I introduce an intuitive distinction between basic and refined taste, and show how this distinction affects questions of faultlessness and parity. Last, I discuss the idea of alethic suberogation in connection with disagreement about refined taste. (shrink)

Stephan Blatti claims to have a new line of reasoning using evolutionary theory that resolves arguments over our deeper natures in favor of the Animalist position that we are identical to Homo sapiens organisms. Blatti thus raises an important question about which views of what we are can take us to be evolved. However, in this response I show that Blatti’s argument using evolution is based upon a false assumption about contemporary biology. I highlight how a better understanding of evolutionary (...) theory allows us to see that the major theories of what we are, including Psychological, Brain and even Soul theories, as well as Animalism, can all accept that we are products of evolution.

According to the form of logical pluralism elaborated by Beall and Restall there is more than one relation of logical consequence. Since they take the relation of logical consequence to reside at the very heart of a logical system, different relations of logical consequence yield different logics. In this paper, we are especially interested in understanding what are the consequences of endorsing Beall and Restall’s version of logical pluralism vis-à-vis the normative guidance that logic is taken to provide to reasoners. (...) In particular, the aim of this paper is threefold. First, in Sections 2 and 3, we offer an exegesis of Beall and Restall’s logical pluralism as a thesis of semantic indeterminacy of our concept of logical consequence – i.e. understood as indeterminacy logical pluralism. Second, in Sections 4 and 5, we elaborate and critically scrutinize three models of semantic indeterminacy that we think are fit to capture Beall and Restall’s indeterminacy logical pluralism. Third, in Section 6, following Beall and Restall’s assumption that the notion of logical consequence has normative significance for deductive reasoning, we raise a series of normative problems for indeterminacy logical pluralism. The overall conclusion that we aim to establish is that Beall and Restall’s indeterminate logical pluralism cannot offer an adequate account of the normative guidance that logic is taken to provide us with in ordinary contexts of reasoning.
