A typical guiding principle of an account of truth is: “truth is objective,” or, to be clear, judging whether an assertion is true or false depends upon how things are in the world rather than how someone or some community believes it to be. Accordingly, whenever a claim is objectively true, its truth conditions ought not depend upon the context in which it is uttered or the utterer making the claim. Part of our ongoing empirical studies surveying people’s responses to (...) questions about truth involved prompts on objectivity. Our studies suggest the following: overall, individuals tend to endorse claims that are consistent with the objectivity of truth; not all conceptions of objectivity are equal, even people who endorse the objectivity of truth sometimes assent to one form of truth’s objectivity over other forms; philosophers and non-philosophers both endorse the objectivity of truth, but the apparent commitment of philosophers is stronger.

Yablo has argued for an alternative form of if-thenism that is more conducive with his figurative fictionalism. This commentary sets out to challenge whether the remainder, ρ, tends to be an inaccurate representation of the conditions that are supposed to complete the enthymeme from φ to Ψ. Whilst by some accounts the inaccuracies shouldn't set off any alarm bells, the truth of ρ is too inexact. The content of ρ, a partial truth, must display a sensitivity to the contextual background (...) conditions for subtraction to work properly in Yablo's view. Using a toy example, I argue that Yablo's subtraction model tends to yield partial truths as remainders that fail to rule out inaccurate expressions that may prove to be problematic for it. (shrink)

Many in philosophy understand truth in terms of precise semantic values, true propositions. Following Braun and Sider, I say that in this sense almost nothing we say is, literally, true. I take the stand that this account of truth nonetheless constitutes a vitally useful idealization in understanding many features of the structure of language. The Fregean problem discussed by Braun and Sider concerns issues about application of language to the world. In understanding these issues I propose an alternative modeling tool (...) summarized in the idea that inaccuracy of statements can be accommodated by their imprecision. This yields a pragmatist account of truth, but one not subject to the usual counterexamples. The account can also be viewed as an elaborated error theory. The paper addresses some prima facie objections and concludes with implications for how we address certain problems in philosophy. (shrink)

Epistemicism is the view that seemingly vague predicates are not in fact vague. Consequently, there must be a sharp boundary between a man who is bald and one who is not bald. Although such a view is often met with incredulity, my aim is to provide a defense of epistemicism in this essay. My defense, however, is backhanded: I argue that the formal commitments of epistemicism are the result of good practical reasoning, not metaphysical necessity. To get to that conclusion, (...) I spend most of the essay arguing that using a formal system like classical logic to manage seemingly vague situations requires practical principles to mediate between the formalism and what it aims to represent.

Knowledge requires truth, and truth, we suppose, involves unflawed representation. Science does not provide knowledge in this sense but rather provides models, representations that are limited in their accuracy, precision, or, most often, both. Truth as we usually think of it is an idealization, one that serves wonderfully in most ordinary applications, but one that can terribly mislead for certain issues in philosophy. This article sketches how this happens for five important issues, thereby showing how philosophical method must take into (...) account the idealized nature of our familiar conception of truth.

It is wholly uncontroversial that measurements-or, more properly, propositions that are measurement reports-are often paradigmatically good cases of propositions that serve the function of evidence. In normal cases it is also obvious that stating such a report is an utterly pedestrian case of successful assertion. So, for example, there is nothing controversial about the following claims: (1) that a proposition to the effect that a particular thermometer reads 104C when properly used to determine the temperature of a particular patient is (...) evidence that the patient in question has a fever and (2) that there is nothing wrong with asserting the proposition that a particular thermometer reads 104C for appropriate reasons of communication, etc. when the thermometer has been properly used to determine the temperature of a particular patient. Here it will be shown that Timothy Williamson’s commitments to a number of principles about knowledge and assertion imply that a whole class of utterly ordinary statements like these that are used as evidence are not really evidence because they are not knowledge and so are (perversely) unassertable according to his principled commitments. This paper deals primarily with the second of these two problems and an alternative account of the norms of assertion is introduced which allows for the assertability of such measurement reports.

The notion of an agent and the notion of a self are connected, for agency is one role played by the self. Millgram argues for a disunity thesis of agency on the basis of extreme incommensurability across some major life events. We propose a similar negative thesis about the self, that it is composed of relatively independent threads reflecting the different roles and different mind-sets of the person's life. Our understanding of those threads is based on theories of the narrative (...) construction of the self. Our disunity thesis is that there need be no overarching narrative that unifies those narrative threads. To explain how the threads hang together to produce coherent action, we make these positive claims: control normally switches smoothly and unconsciously between threads as circumstances require, within one thread there is likely to be acknowledgment of other threads, some situations require a temporary blending of threads, and some plans and policies reach across different threads and contribute to some coordination among them. Our account of a self provides an account of agency that has merits in comparison to Millgram's. Our narrative approach allows explanations of actions beyond rational deliberation. (shrink)

Hard Truths is an important book in its own right. It is also the latest contribution to a complex and impressive project that Elijah Milligram has been developing from his first book onwards. There he characterized practical induction as a type of reasoning that enables agents to learn from experiences of the new and the unfamiliar, agents whose inferences are from beliefs that they have formed either ‘in ways that have a suitable amount to do with [their] truth’, or, when (...) ‘the appeal to truth is unhelpful’, in ways that underwrite such inferences as they are committed to drawing . In his introduction to his anthology on practical reasoning, Millgram catalogued the presently competing theories of practical reasoning, posing the question: what kind of reasoning should we employ in deciding between the claims of rival theories? The subtitle of his third book , ‘Practical Reasoning as a Foundation for Moral Theory’, already suggests its central thesis, that we should first survey the range of theories of practical reasoning , should then identify which moral theory it is with which each theory of practical reasoning is paired , should next decide which theory of practical reasoning is correct , and, finally, should adopt the moral theory paired with that theory of practical reasoning. There are at least three clusters of problems that badly need extended attention, if the claims of these three books are to be sustained: one concerning the account of truth presupposed by Millgram, a second to do with the inferences that we need to employ, and a third concerning the unity of reasoning agents. All three provide Hard Truths with subject-matter, but Millgram’s principal focus is …. (shrink)

A wave of recent philosophical work on practical rationality is organized by the following implicit argument: Practical reasoning is figuring out what to do; to do is to act; so the forms of practical inference can be derived from the structure or features of action. Now it is not as though earlier work, in analytic philosophy, had failed to register the connection between action and practical rationality; in fact, practical reasoning was usually picked out as, roughly, reasoning directed toward action. (...) But for much of the twentieth century, attention moved quickly away from this initial delineation of the subject area, to the interplay of beliefs and desires within the mind (Humean theories, including their Davidsonian and Williamsian variants), or to procedures for checking that a plan of action was supported by sufficient yet consistent reasons (Kantian theories), or to the ultrarefined sensibilities of the practically intelligent reasoner (Aristotelian theories). The hallmark of the emerging family of treatments to be surveyed here is, first, the sustained attention paid to answering the question, "What does it take to be an action (at all)?", and second, the use made of a distinction between full-fledged action and its lesser relatives. (Characterizations and terminology vary, but often the less robust alternative is called "mere activity" or "mere behavior".) Very schematically, these arguments for a theory of practical reasoning try to show that reasons brought to bear on choice must have some particular logical form, if action is not to lapse into something less than that.

The author uses a series of examples to illustrate two versions of a new, nonprobabilist principle of epistemic rationality, the special and general versions of the metacognitive, expected relative frequency principle. These are used to explain the rationality of revisions to an agent’s degrees of confidence in propositions based on evidence of the reliability or unreliability of the cognitive processes responsible for them—especially reductions in confidence assignments to propositions antecedently regarded as certain—including certainty-reductions to instances of the law of excluded (...) middle or the law of noncontradiction in logic or certainty-reductions to the certainties of probabilist epistemology. The author proposes special and general versions of the MERF principle and uses them to explain the examples, including the reasoning that would lead to thoroughgoing fallibilism—that is, to a state of being certain of nothing. The author responds to the main defenses of probabilism: Dutch Book arguments, Joyce’s potential accuracy defense, and the potential calibration defenses of Shimony and van Fraassen by showing that, even though they do not satisfy the probability axioms, degrees of belief that satisfy the MERF principle minimize expected inaccuracy in Joyce’s sense; they can be externally calibrated in Shimony and van Fraassen’s sense; and they can serve as a basis for rational betting, unlike probabilist degrees of belief, which, in many cases, human beings have no rational way of ascertaining. The author also uses the MERF principle to subsume the various epistemic akrasia principles in the literature. Finally, the author responds to Titelbaum’s argument that epistemic akrasia principles require that we be certain of some epistemological beliefs, if we are rational. (shrink)

This paper distinguishes between various different conceptions of behaviour and action before exploring an accompanying variety of distinct things that ‘action explanation’ may plausibly amount to viz. different objectives of action explanation. I argue that a large majority of philosophers are guilty of conflating many of these, consequently offering inadequate accounts of the relation between actions and our reasons for performing them. The paper ends with the suggestion that we would do well to opt for a pluralistic understanding of action (...) and its explanations. (shrink)

It is natural to think of precise probabilities as being special cases of imprecise probabilities, the special case being when one’s lower and upper probabilities are equal. I argue, however, that it is better to think of the two models as representing two different aspects of our credences, which are often vague to some degree. I show that by combining the two models into one model, and understanding that model as a model of vague credence, a natural interpretation arises that (...) suggests a hypothesis concerning how we can improve the accuracy of aggregate credences. I present empirical results in support of this hypothesis. I also discuss how this modeling interpretation of imprecise probabilities bears upon a philosophical objection that has been raised against them, the so-called inductive learning problem. (shrink)

In Hard Truths, Elijah Millgram maintains that analytic philosophy rests on a mistake. 1 It is committed to bivalence – the contention that every truth bearer is either true or false. As a result of this commitment, its views about logic and metaphysics are profoundly misguided. He believes that rather than restricting ourselves to two truth values, we should recognize a plethora of partial truths – sentences, beliefs and opinions that are partly true or true in a way. These are (...) located on a multidimensional continuum between truth and falsity. Millgram never says exactly what partial truth is. The closest he comes is ‘Partial truth is the not fully articulated standard, or family of standards to which we hold [utterances, inscriptions and thoughts] in partial truth inferences’ , where partial truth inferences are those used in cases where ‘there is a recognized mismatch between representation and world – but not in any way that requires changing the representations’ . A critical issue then is what constitutes such a mismatch. I will argue that Millgram’s reasons for recognizing partial truths rest on untenable conceptions of logic, truth and language. Perhaps there are partial truths; perhaps recognizing them would enhance our logic or metaphysics. But Millgram’s arguments fail to show it. 1. Logic Recognizing that there can be some truth in sentences that as a whole are false is not unprecedented. Analyses by Ullian and Goodman 2 and, more recently, Yablo 3 reveal how a false sentence or proposition can be true about a particular item. ‘The dog barks and the cat speaks French’ is true about the dog, even though the conjunction as a whole is false. This does not undermine classical logic. Rather, such analyses reveal that truth about a particular subject matter is more fine grained than truth simpliciter. ‘True …. (shrink)

This book is a sustained defense of the compatibility of the presence of idealizations in the sciences and scientific realism. So, the book is essentially a detailed response to the infamous arguments raised by Nancy Cartwright to the effect that idealization and scientific realism are incompatible.

Humeans take reality to be devoid of ‘necessary connections’: things just happen. Laws of nature are to be understood in terms of what ‘just happens’, not vice versa. Here the Humean needs some conception of what it is that ‘just happens’ – a conception of the Humean mosaic. Lewis’s Humeanism incorporates such a conception in the form of a Lewis-style metaphysics of objects, properties, and modality. Newer versions of Humeanism about laws of nature, such as the Better Best Systems approach, (...) typically reject such a Lewisian metaphysics, but it remains unclear what they can offer in its place. By exploring different candidate conceptions, this paper sheds light on the limits of Humeanism about laws of nature: not all conceptions of the Humean mosaic form a suitable basis for a Humean theory of laws. In fact, only a metaphysics roughly in line with Lewis’s will do. The paper ends with a tentative generalization of this result, thus pointing to the ‘limit’ of Humeanism in general: taking the Humean way of thinking to its limit results in a rejection of the whole idea of such a mosaic – and hence of Humean mosaic-based accounts of anything.

Nietzsche thought at one point that predication originated through the misapplication of names for particulars to further particulars. I doubt myself that this is where the device came from, although one does occasionally encounter usage – such as ‘another Vietnam’ – that evidently does arise in this manner. However, his account of predication is a useful model for a more sophisticated device which we in fact deploy, namely, the intentional misdescription of one circumstance or another in the interests of expedited (...) inference, often via the misapplication of a predicate. I don’t believe that ‘… is a leaf’ is a systematic reapplication of the name of some ur-leaf, but just the other day, I told my gardener that the leaves were off the tree, and that she could come in and work on my pond. I was triggering an inference rule we both accept: that you schedule fall cleanup once the leaves are off the tree. Rather than describe the actual state of the tree , and then renegotiate the rule to match, it was simpler to work with the misdescriptions. My respondents recall that devices such as predication are flexible anyway; they conclude that there is no need to misapply them. Let me try to get you to think twice about the assumption that flexibility pre-empts misapplication. But as I proceed, bear in mind that my illustrations are not intended as an argument. Any given illustration can be read either as a misapplication of a description, or alternatively as a correct application of a predicate, whose use in context is controlled by, perhaps, the sort of techniques discussed by David Lewis ….

In Hard Truths Elijah Millgram argues that ‘partial truth’ is pervasive and for that reason bivalence 1 may rarely be assumed. As classical logic assumes bivalence, and inferences from partial truths to partial truths are central to our thinking, classical logic rarely has application, the argument continues. And so we must develop an account of inference from partial truths to partial truths; as well, our metaphysics must be revised. While the novel positions of Hard Truths 2 raise many interesting challenges, (...) my focus is limited to offering an alternative to Millgram’s account of predication and to exploring some issues raised by his appeal to ‘fit’ in his definitions of truth and partial truth. 1. Introduction to partial truth Millgram defines truth and partial truth in terms of fit, as follows: Advancing a claim as fully true demands complete fit; assessing a claim as partially true allows for slack … but only so much of it. Claims are said to completely fit, slackly fit or not fit, the world, in §6.3. But, the word ‘fit’ is first introduced in §1.2, and it is experience or proto-experience, that fits into moulds provided by claims, thoughts, sentences and predicates. I won’t dwell on which fits what, 3 but on the notion of a ‘complete fit’ and the contrast with a ‘slack fit’; this discussion leads me to ponder the clarity and implications of appealing to these notions in definitions like the above. Millgram’s explanation of fit comes in the context of his account of predication, according to which, most predicates do not quite apply. It’s this that is primarily responsible for his promotion of partial truth. I sketch an alternative account of language whereby predicates do apply because language has come to life as a constituent of the things we do: …. (shrink)
