  1. Knowledge from Blindspots.Rhys Borchert, Juan Comesaña & Tim Kearl - 2023 - In Rodrigo Borges & Ian Schnee (eds.), Illuminating Errors: New Essays on Knowledge from Non-Knowledge. New York, NY: Routledge. pp. 76-91.
    No False Lemmas (NFL) says: necessarily, S’s belief that p is knowledge only if it is not inferred from any falsehood. Its proponents argue that alleged counterexamples to NFL are really cases of knowledge despite falsehood, wherein the false premise is inessential to the inference; perhaps some nearby truth does the justificatory heavy-lifting. We argue that there can be cases of inferential knowledge from a blindspot premise. Given that in such cases the relevant falsehood is essential to the inference, one (...)

  • What can we know about unanswerable questions?Thomas Raleigh - forthcoming - Philosophical Quarterly.
    I present two arguments that aim to establish logical limits on what we can know. More specifically, I argue for two results concerning what we can know about questions that we cannot answer. I also discuss a line of thought, found in the writings of Pierce and of Rescher, in support of the idea that we cannot identify specific scientific questions that will never be answered.

  • Epistemic characterizations of validity and level-bridging principles.Joshua Schechter - 2024 - Philosophical Studies 181 (1):153-178.
    How should we understand validity? A standard way to characterize validity is in terms of the preservation of truth (or truth in a model). But there are several problems facing such characterizations. An alternative approach is to characterize validity epistemically, for instance in terms of the preservation of an epistemic status. In this paper, I raise a problem for such views. First, I argue that if the relevant epistemic status is factive, such as being in a position to know or (...)

  • Quantum Epistemology and Constructivism.Patrick Fraser, Nuriya Nurgalieva & Lídia del Rio - 2023 - Journal of Philosophical Logic 52 (6):1561-1574.
    Constructivist epistemology posits that all truths are knowable. One might ask to what extent constructivism is compatible with naturalized epistemology and knowledge obtained from inference-making using successful scientific theories. If quantum theory correctly describes the structure of the physical world, and if quantum theoretic inferences about which measurement outcomes will be observed with unit probability count as knowledge, we demonstrate that constructivism cannot be upheld. Our derivation is compatible with both intuitionistic and quantum propositional logic. This result is implied by (...)

    Stephenson (2022) has argued that Kant’s thesis that all transcendental truths are transcendentally a priori knowable leads to omniscience of all transcendental truths. His arguments depend on luminosity principles and closure principles for transcendental knowability. We will argue that one pair of a luminosity and a closure principle should not be used, because the closure principle is too strong, while the other pair of a luminosity and a closure principle should not be used, because the luminosity principle is too strong.

    The knower paradox states that the statement ‘We know that this statement is false’ leads to inconsistency. This article presents a fresh look at this paradox and some well-known solutions from the literature. Paul Égré discusses three possible solutions that modal provability logic provides for the paradox by surveying and comparing three different provability interpretations of modality, originally described by Skyrms, Anderson, and Solovay. In this article, some background is explained to clarify Égré’s solutions, all three of which hinge on (...)

  • Problems for factive accounts of assertion.Sven Rosenkranz - 2023 - Noûs 57 (1):128-143.
    The knowledge account of assertion construes assertion as subject to constitutive norms. In its standard version, it combines a wide scope obligation not to assert p without knowing p, with narrow scope principles specifying conditions under which it is permissible to assert p, where the notions of obligation and permission are duals and behave uniformly for variable p. It is argued that, given natural assumptions about the logic of ‘ought’, the account proves incoherent. The argument generalizes to accounts that substitute (...)

    Intuitionistic epistemic logic by Artemov and Protopopescu (Rev Symb Log 9:266–298, 2016) accepts the axiom “if A, then A is known” (written $$A \supset K A$$ ) in terms of the Brouwer–Heyting–Kolmogorov interpretation. There are two variants of intuitionistic epistemic logic: one with the axiom “ $$KA \supset \lnot \lnot A$$ ” and one without it. The former is called $$\textbf{IEL}$$, and the latter is called $$\textbf{IEL}^{-}$$. The aim of this paper is to study first-order expansions (with equality and function (...)

The Humberstone paradox only requires the assumption that knowledge distributes over conjunction and as such can be viewed as a reductio against the (...)

    Since Fitch’s proof that not all propositions are knowable, philosophers have analysed the concept of knowability and sought a schema for the knowable propositions. A recent development in dynamic epistemic logic (DEL) has been to read ‘knowable’ as ‘known after an announcement’. Arbitrary Public Announcement Logic (APAL) and Sequential Public Announcement Logic (SPAL) are two DELs that have depicted this reading of knowability. We argue that neither APAL nor SPAL provide a satisfactory and principled schema of the knowable propositions. Instead, (...)

    In this paper, we introduce a notion of ‘disjunctive ignorance’, which is a weak combination of two forms of ignorance in the literature. We propose a logical language with ‘disjunctive ignorance’ as a sole modality, explore the logical properties of this notion and its related notions, and axiomatize it over various frame classes. By finding suitable reduction axioms, we extend the results to the case of public announcements and apply it to Moore-like sentences.

It is argued that realism and anti-realism form a dialetheic pair: While they are in fact each other’s logical opposite, nevertheless, both are true (and both false). First, several reasons why one might think such a thing are presented. These reasons are merely the beginning, however. In the following sections, the dialetheic conclusion (...)

If the indefinite extensibility of contingent truth is developed in an analogous fashion to the most promising models of the indefinite extensibility of the concept set, plausible principles permit the derivation of modal collapse.

The book demonstrates how epistemic modality and hyperintensionality relate to the computational theory of mind; metaphysical modality and hyperintensionality; the types of mathematical modality and hyperintensionality; to the epistemic status of large cardinal axioms, undecidable (...)

  • Yet another new cosmological argument.Christopher Gregory Weaver - 2016 - International Journal for Philosophy of Religion 80 (1):11-31.
    I argue that the existence of a necessary concrete being can be derived from an exceedingly weak causal principle coupled with two contingent truths one of which falls out of very popular positions in contemporary analytic metaphysics. I then show that the argument resists a great many objections commonly lodged against natural theological arguments of the cosmological variety.

  • (1 other version)Truth, Demonstration and Knowledge.Elia Zardini - 2015 - Theoria: Revista de Teoría, Historia y Fundamentos de la Ciencia 30 (3):365-392.
    After introducing semantic anti-realism and the paradox of knowability, the paper offers a reconstruction of the anti-realist argument from understanding. The proposed reconstruction validates an unrestricted principle to the effect that truth requires the existence of a certain kind of “demonstration”. The paper shows that that principle fails to imply the problematic instances of the original unrestricted feasible-knowability principle but that the overall view underlying the new principle still has unrestricted epistemic consequences. Appealing precisely to the paradox of knowability, the (...)

  • Superassertibility and the Equivalence Schema: A Dilemma for Wright’s Antirealist.Deborah C. Smith - 2007 - Synthese 157 (1):129-139.
    In _Truth and Objectivity_, Crispin Wright argues that the notion of superassertibility affords the antirealist (with respect to a given range of discourse) a viable alternative to the realist’s more robust notion of truth. Toward this end, he endeavors to prove that a superassertibility predicate can satisfy the traditional equivalence schema: it is true that P iff P. (Wright takes satisfaction of this schema to be a criterion of adequacy for any viable truth predicate.) In this paper, I will argue (...)

  • Counterfactual theories of knowledge and the notion of actuality.Jan Heylen - 2016 - Philosophical Studies 173 (6):1647-1673.
    The central question of this article is how to combine counterfactual theories of knowledge with the notion of actuality. It is argued that the straightforward combination of these two elements leads to problems, viz. the problem of easy knowledge and the problem of missing knowledge. In other words, there is overgeneration of knowledge and there is undergeneration of knowledge. The combination of these problems cannot be solved by appealing to methods by which beliefs are formed. An alternative solution is put (...)
