I am concerned with epistemic closure—the phenomenon in which some knowledge requires other knowledge. In particular, I defend a version of the closure principle in terms of analyticity; if an agent S knows that p is true and that q is an analytic part of p, then S knows that q. After targeting the relevant notion of analyticity, I argue that this principle accommodates intuitive cases and possesses the theoretical resources to avoid the preface paradox.

I provide a theory of the metaphysical foundations of identity: an account what grounds facts of the form a=b. In particular, I defend the claim that indiscernibility grounds identity. This is typically rejected because it is viciously circular; plausible assumptions about the logic of ground entail that the fact that a=b partially grounds itself. The theory I defend is immune to this circularity.

I provide an analysis of sentences of the form ‘To beFis to beG’ in terms of exact truth-maker semantics—an approach that identifies the meanings of sentences with the states of the world directly responsible for their truth-values. Roughly, I argue that these sentences hold just in case that which makes somethingFalso makes itG. This approach is hyperintensional and possesses desirable logical and modal features. In particular, these sentences are reflexive, transitive, and symmetric, and if they are true, then they are (...) necessarily true, and it is necessary that all and onlyFs areGs. I motivate my account over Correia and Skiles’ [11] prominent alternative and close by defining an irreflexive and asymmetric notion of analysis in terms of the symmetric and reflexive notion.

Among contemporary philosophers, there is widespread consensus that begging the question is a grave argumentative flaw. However, there is presently no satisfactory analysis of what this flaw consists of. Here, I defend a notion of question-begging in terms of analyticity. In particular, I argue that an argument begs the question just in case its conclusion is an analytic part of the conjunction of its premises.

Two families of positions dominate debates over a metaphysically reductive analysis of knowledge. Traditionalism holds that knowledge has a complete, uniquely identifying analysis, while knowledge-first epistemology contends that knowledge is primitive—admitting of no reductive analysis whatsoever. Drawing on recent work in metaphysics, I argue that these alternatives fail to exhaust the available possibilities. Knowledge may have a merely partial analysis: a real definition that distinguishes it from some, but not all other things. I demonstrate that this position is attractive; it (...) evades concerns that its rivals face. (shrink)

It is often said that there are two varieties of identity theory. Type-identity theorists interpret physicalism as the claim that every property is identical to a physical property, while token-identity theorists interpret it as the claim that every particular is identical to a physical particular. The aim of this paper is to undermine the distinction between the two. Drawing on recent work connecting generalized identity to truth-maker semantics, I demonstrate that these interpretations are logically equivalent. I then argue that each (...) has the resources to resolve problems facing the other. (shrink)

I take some initial steps toward a theory of real definition, drawing upon recent developments in higher-order logic. The resulting account allows for extremely fine-grained distinctions (it can distinguish between any relata that differ in their syntactic structure, while avoiding the Russell-Myhill problem). It is the first account that can consistently embrace three desirable logical principles that initially appear to be incompatible: the Identification Hypothesis (if F is, by definition, G, then there is a sense in which F is the (...) same as G), Irreflexivity (there are no reflexive definitions), and Leibniz’s Law. Additionally, it possesses the resources needed to resolve the paradox of analysis. (shrink)

This paper is concerned with counterfactual logic and its implications for the modal status of mathematical claims. It is most directly a response to an ambitious program by Yli-Vakkuri and Hawthorne, who seek to establish that mathematics is committed to its own necessity. I demonstrate that their assumptions collapse the counterfactual conditional into the material conditional. This collapse entails the success of counterfactual strengthening, which is controversial within counterfactual logic, and which has counterexamples within pure and applied mathematics. I close (...) by discussing the dispensability of counterfactual conditionals within the language of mathematics. (shrink)

Consequentialists maintain that an act is morally right just in case it produces the best consequences of any available alternative. Because agents are ignorant about some of their acts’ consequences, they cannot be certain about which alternative is best. Kagan contends that it is reasonable to assume that unforeseen good and bad consequences roughly balance out and can be largely disregarded. A statistical argument demonstrates that Kagan’s assumption is almost always false. An act’s foreseeable consequences are an extremely poor indicator (...) of the goodness of its overall consequences. Acting based on foreseeable consequences is barely more reliably good than acting completely at random. (shrink)

This paper concerns the grounds of nonground: what it is in virtue of that facts of the form [F1 does not ground F2] hold. While the literature on iterated ground is expansive, there is comparatively little written on the grounds of nonground. I argue that nonground is grounded in distinctness from ground. If F1 does not ground F2, then [F1 does not ground F2] is grounded in the fact that F1 is distinct from that which does ground F2. While this (...) proposal strikes me as natural, it faces puzzles involving conjunction, contingency, and cardinality. The bulk of this paper explores how the view might be precisified, and how these puzzles might be resolved. (shrink)

This paper presents a puzzle about the logic of real definition. I demonstrate that five principles concerning definition—that it is coextensional and irreflexive, that it applies to its cases, that it permits expansion, and that it is itself defined—are logically incompatible. I then explore the advantages and disadvantages of each principle—one of which must be rejected to restore consistency.

I develop an account of disciplinary level in terms of truth-maker semantics. In particular, I exploit the mereological structure of states of affairs—which is central to the truth-maker approach—to provide conditions in which one discipline occupies a higher level than another.

This paper consists of an investigation of three debates concerning propositional identity: the tension between structured propositions and higher-order logic, the principle Only Logical Circles, and Kaplan’s Paradox. The literature at large has mistaken the consequences of each of these debates. Structuralists are not committed to the claim that identical properties have different extensions; rather, they are committed to existence monism. Only Logical Circles does not preclude the identification of green in terms of grue; some further (and, as of yet, (...) undisclosed) principle is required for that result. And Kaplan’s Paradox does not count against the possible-worlds conception of propositions; it applies to every account of propositions whatsoever. (shrink)

Monism is the claim that only one object exists. While few contemporary philosophers endorse monism, it has an illustrious history – stretching back to Bradley, Spinoza and Parmenides. In this paper, I show that plausible assumptions about the higher-order logic of property identity entail that monism is true. Given the higher-order framework I operate in, this argument generalizes: it is also possible to establish that there is a single property, proposition, relation, etc. I then show why this form of monism (...) is inconsistent; because all propositions are identical, p is identical to ~p – and so they have the same truth-value. At least one of the assumptions that generate higher-order monism must be rejected. (shrink)

I show that the theory of definition in Definition by Proxy can consistently embrace the principles I show to be inconsistent in Definition.

Purity is the principle that fundamental facts only have fundamental constituents. In recent years, it has played a significant role in metaphysical theorizing—but its logical foundations are underdeveloped. I argue that recent advances in higher-order logic reveal a subtle ambiguity regarding Purity’s interpretation; there are stronger and weaker versions of that principle. The arguments for Purity only support the weaker interpretation, but arguments that employ it only succeed if the stronger interpretation is true. As a result, nearly every metaphysician who (...) has appealed to Purity has made a mistake—in that the inferences that they make are not justified by the arguments that they provide. (shrink)

This paper investigates the metaphysics in higher-order counterfactual logic. I establish the necessity of identity and distinctness and show that the logic is committed to vacuism, which entails that all counteridenticals are true. I prove the Barcan, Converse Barcan, Being Constraint and Necessitism. I then show how to derive the Identity of Indiscernibles in counterfactual logic. I study a form of maximalist ontology which has been claimed to be so expansive as to be inconsistent. I show that it is equivalent (...) to the collapse of the counterfactual into the material conditional---which is itself equivalent to the modal logic TRIV. TRIV is consistent, from which it follows that maximalism is, surprisingly, consistent. I close by arguing that stating the limit assumption requires a higher-order logic. (shrink)

The Identity of Indiscernibles is the principle that objects cannot differ only numerically. It is widely held that one interpretation of this principle is trivially true: the claim that objects that bear all of the same properties are identical. This triviality ostensibly arises from haecceities (properties like \textit{is identical to a}). I argue that this is not the case; we do not trivialize the Identity of Indiscernibles with haecceities, because it is impossible to express the haecceities of indiscernible objects. I (...) then argue that this inexpressibility generalizes to all of their trivializing properties. Whether the Identity of Indiscernibles is trivially true ultimately turns on whether we can quantify over properties that we cannot express. (shrink)

Edward Craig and Michael Hannon agree that the function of knowledge is to enable us to identify informants whose word we can safely take. This requires that knowers display a publicly recognizable mark. Although this might suffice for information transfer, I argue that the position that emerges promotes testimonial injustice, since the mark of a good informant need not be shared by all who are privy to the facts we seek. I suggest a way the problem might be alleviated.

Understanding, as I construe it, is holistic. It is a matter of how commitments mesh to form a mutually supportive, independently supported system of thought. It is advanced by bootstrapping. We start with what we think we know and build from there. This makes education continuous with what goes on at the cutting edge of inquiry. Methods, standards, categories and stances are as important as facts. So something like E. D. Hirsch’s list of facts every fourth grader should know is (...) slightly silly. What makes for a good fourth grade education is not the set of facts the fourth grader knows, but the level of understanding she has achieved and the resources she can deploy to advance that understanding. Facts are part of the story, but so are fictions, methods, standards, and categories. A major part of understanding is recognizing what problems remain to be solved. (shrink)

Recently, growing numbers of interns, apprentices, and volunteers are being recruited to work seasonally on ecologically oriented and organic farms across the global north. To date, there has been very little research examining these emergent forms of non-waged work. In this paper, we analyze the relationships between non-waged agricultural work and the economic circumstances of small- to medium-size farms and the non-economic ambitions of farm operators. We do so through a quantitative and qualitative analysis of farmers’ responses to two surveys (...) we conducted of farmers using non-waged workers in Ontario, Canada. We situate our analysis within debates on the agrarian question, which we contend requires an account for both the economic and non-economic dimensions of new forms of non-waged work on farms. We suggest that many ecologically oriented farm operators are struggling financially and report low gross on-farm revenues and personal incomes. We argue that in addition to relying on off-farm incomes and self-exploitation, many farms are managing to persist in a challenging economic climate through their use of intern, apprentice, and volunteer labor. However, we also suggest that the growth of non-waged work on farms is not simply being driven by economic processes but also a series of non-economic relationships focused on non-institutional farmer training, the pursuit of sustainability, and social movement building. We suggest, the “economic” and “non-economic” dimensions of internships, apprenticeships, and forms of volunteerism sit uneasily alongside of one another, generating questions about the politics, ethics, and sustainability of non-waged work and ecological farming.

Teaching is not testimony. Although both convey information, they have different uptake requirements. Testimony aims to impart information and typically succeeds if the recipient believes that informationon account of having been told by a reliable informant. Teaching aims to equip learners to go beyond the information given—to leverage that information to broaden, deepen, and critique their current understanding of a topic. Teaching fails if the recipients believe the information only because it is what they have been told.

Testimony consists in imparting information without supplying evidence or argument to back one’s claims. To what extent does testimony convey epistemic warrant? C. J. A. Coady argues, on Davidsonian grounds, that (1) most testimony is true, hence (2) most testimony supplies warrant sufficient for knowledge. I appeal to Grice’s maxims to undermine Coady’s argument and to show that the matter is more complicated and context-sensitive than is standardly recognized. Informative exchanges take place within networks of shared, tacit assumptions that affect (...) the scope and strength of our claims, and the level of warrant required for their responsible assertion. The maxims explain why different levels of warrant are transferred in different contexts. (shrink)

Science relies on models and idealizations that are known not to be true. Even so, science is epistemically reputable. To accommodate science, epistemology should focus on understanding rather than knowledge and should recognize that the understanding of a topic need not be factive. This requires reconfiguring the norms of epistemic acceptability. If epistemology has the resources to accommodate science, it will also have the resources to show that art too advances understanding.

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. (shrink)

The book contains a unique epistemological position that deserves serious consideration by specialists in the subject."--Bruce Aune, University of Massachusetts.

Answers set the stage for new questions. Reconfigured terrains require new maps. We endedReconceptions with the words constructionalism always has plenty to do. The papers in this volume prove our point. They raise issues and disclose avenues that merit further investigation. In what follows, I venture some brief replies that answer objections and indicate areas that deserve further study.

To understand a term or other symbol, I argue that it is generally neither necessary nor sufficient to assign it a unique determinate reference. Independent of and prior to investigation, it is frequently indeterminate not only whether a sentence is true, but also what its truth conditions are. Nelson Goodman's discussions of likeness of meaning are deployed to explain how this can be so.
