  1. Conditionals, Context, and the Suppression Effect.Fabrizio Cariani & Lance J. Rips - 2017 - Cognitive Science 41 (3):540-589.
    Modus ponens is the argument from premises of the form If A, then B and A to the conclusion B. Nearly all participants agree that the modus ponens conclusion logically follows when the argument appears in this Basic form. However, adding a further premise can lower participants’ rate of agreement—an effect called suppression. We propose a theory of suppression that draws on contemporary ideas about conditional sentences in linguistics and philosophy. Semantically, the theory assumes that people interpret an indicative (...)

  2. Sufficient Conditions for Counterfactual Transitivity and Antecedent Strengthening.Tristan Grøtvedt Haze - 2023 - American Philosophical Quarterly 60 (3):237-247.
    This paper is about two controversial inference-patterns involving counterfactual or subjunctive conditionals. Given a plausible assumption about the truth-conditions of counterfactuals, it is shown that one can't go wrong in applying hypothetical syllogism (i.e., transitivity) so long as the set of worlds relevant for the conclusion is a subset of the sets of worlds relevant for the premises. It is also shown that one can't go wrong in applying antecedent strengthening so long as the set of worlds relevant for (...)

  3. Valid Arguments as True Conditionals.Andrea Iacona - 2023 - Mind 132 (526):428-451.
    This paper explores an idea of Stoic descent that is largely neglected nowadays, the idea that an argument is valid when the conditional formed by the conjunction of its premises as antecedent and its conclusion as consequent is true. As it will be argued, once some basic features of our naıve understanding of validity are properly spelled out, and a suitable account of conditionals is adopted, the equivalence between valid arguments and true conditionals makes perfect sense. The account (...)

  4. Against the Taking Condition.Conor McHugh & Jonathan Way - 2016 - Philosophical Issues 26 (1):314-331.
    According to Paul Boghossian and others, inference is subject to the taking condition: it necessarily involves the thinker taking his premises to support his conclusion, and drawing the conclusion because of that fact. Boghossian argues that this condition vindicates the idea that inference is an expression of agency, and that it has several other important implications too. However, we argue in this paper that the taking condition should be rejected. The condition gives rise to several serious prima facie problems and (...)

  5. The Paradoxical Associated Conditional of Enthymemes.Gilbert Plumer - 2000 - In Christopher W. Tindale, Hans V. Hansen & Elmar Sveda (eds.), Argumentation at the Century's Turn [CD-ROM]. Ontario Society for the Study of Argumentation. pp. 1-8.
    Expressing a widely-held view, David Hitchcock claims that "an enthymematic argument ... assumes at least the truth of the argument's associated conditional ... whose antecedent is the conjunction of the argument's explicit premises and whose consequent is the argument's conclusion." But even definitionally, this view is problematic, since an argument's being "enthymematic" or incomplete with respect to its explicit premises means that the conclusion is not implied by these premises alone. The paper attempts to specify the ways in which the (...)

  6. Arguments, Suppositions, and Conditionals.Pavese Carlotta - forthcoming - Semantics and Linguistic Theory.
    Arguments and conditionals are powerful means language provides us to reason about possibilities and to reach conclusions from premises. These two kinds of constructions exhibit several affinities—e.g., they both come in different varieties depending on the mood; they share some of the same connectives (i.e., ‘then’); they allow for similar patterns of modal subordination. In the light of these affinities, it is not surprising that prominent theories of conditionals—old and new suppositionalisms as well as dynamic theories of (...)—as well as certain reductive theories of arguments tend to semantically assimilate conditionals and arguments. In this paper, I shall marshall some linguistic evidence as well as some theoretical considerations for thinking that, despite these similarities, arguments and conditionals should be given a different semantics and I shall lay out a framework that can capture at least some of their affinities while accounting for their outstanding differences.

  7. Inference Without the Taking Condition.Declan Smithies - 2023 - In Kevin McCain, Scott Stapleford & Matthias Steup (eds.), Seemings: New Arguments, New Angles. New York, NY: Routledge. pp. 130-146.
    What is involved in making an inference? This chapter argues against what Paul Boghossian calls the Taking Condition: "Inferring necessarily involves the thinker taking his premises to support his conclusion and drawing his conclusion because of that fact" (2014: 5). I won’t argue that the Taking Condition is incoherent: that nothing can coherently play the role that takings are supposed to play in inference. Instead, I’ll argue that it cannot plausibly explain all the inferential knowledge that we ordinarily take ourselves (...)

  8. Conditionals all the way down.Matheus Silva - manuscript
    It is commonly accepted that unconditional statements are clearer and less problematic than conditional ones. This article challenges this belief by proposing that all unconditional statements can be reduced to conditional ones since epistemic justification is inherently conditional in nature. The distinction between unconditional and conditional statements is similar to the distinction between assumptions and premises, which is an idealization that results from our attempts to limit epistemic complexity. This has perplexing consequences: (1) since any ordinary statement can be viewed (...)

  9. Indicative Conditionals are Material - Expanding the Survey.Matheus Martins Silva - manuscript
    Adam Rieger (2013) has carried out a survey of arguments in favour of the material account of indicative conditionals. These arguments involve simple and direct demonstrations of the material account. I extend the survey with new arguments and clarify the logical connections among them. I also show that the main counter-examples against these arguments are not successful either because their premises are just as counter-intuitive as the conclusions, or because they depend on contextual fallacies. The conclusion is that the (...)

  10. Towards a Radically Pragmatic Theory of If-Conditionals.Gunnar Björnsson - 2011 - In Ken Turner (ed.), Making Semantics Pragmatic. Emerald Group Publishing.
    It is generally agreed that constructions of the form “if P, Q” are capable of conveying a number of different relations between antecedent and consequent, with pragmatics playing a central role in determining these relations. Controversy concerns what the conventional contribution of the if-clause is, how it constrains the pragmatic processes, and what those processes are. In this essay, I begin to argue that the conventional contribution of if-clauses to semantics is exhausted by the fact that these clauses introduce a (...)

  11. Why Are There No Conditionals in Aristotle’s Logic?David Ebrey - 2015 - Journal of the History of Philosophy 53 (2):185-205.
    Aristotle presents a formal logic in the Prior Analytics in which the premises and conclusions are never conditionals. In this paper I argue that he did not simply overlook conditionals, nor does their absence reflect a metaphysical prejudice on his part. Instead, he thinks that arguments with conditionals cannot be syllogisms because of the way he understands the explanatory requirement in the definition of a syllogism: the requirement that the conclusion follow because of the premises. The key (...)

    The aim of this paper is to show that for Kant, a combination of epigenesis and monogenesis is the condition of possibility of anthropology as he conceives of it and that moreover, this has crucial implications for the biological dimension of his account of human nature. More precisely, I begin by arguing that Kant’s conception of mankind as a natural species is based on two premises: firstly the biological unity of the human species (monogenesis of the human races); and secondly (...)

  13. Justifying the State from Rights-Based Libertarian Premises.J. Mikael Olsson - 2016 - Libertarian Papers 8.
    Although many libertarians share similar moral foundations, they disagree about whether the state can be justified. The most famous libertarian attempt to justify the state is that of Robert Nozick. This attempt has been criticized by, among others, the libertarian anarchist Murray Rothbard. In this article, Nozick’s theory and Rothbard’s critique are discussed, as well as some other attempts to justify the state from libertarian premises. Keeping the criticisms of those theories in mind, an alternative theory, which attempts to bypass (...)

  14. When it is Not Logically Necessary for a Necessary Condition of Value to be Valuable.Michael Kowalik - manuscript
    The premise that it is logically necessary for a necessary condition of value to be valuable is sometimes used in metaethics in support of the claim that agency, or some constitutive condition of agency or action, has value for all agents. I focus on the most recent application of this premise by Caroline T. Arruda and argue that the premise is false. Despite this defect the relevant evaluative step could still work just in case of agency if (...)

  15. A 4-valued logic of strong conditional.Fabien Schang - 2018 - South American Journal of Logic 3 (1):59-86.
    How to say no less, no more about conditional than what is needed? From a logical analysis of necessary and sufficient conditions (Section 1), we argue that a stronger account of conditional can be obtained in two steps: firstly, by reminding its historical roots inside modal logic and set-theory (Section 2); secondly, by revising the meaning of logical values, thereby getting rid of the paradoxes of material implication whilst showing the bivalent roots of conditional as a speech-act based on affirmations (...)

    This paper develops the idea that valid arguments are equivalent to true conditionals by combining Kripke’s theory of truth with the evidential account of conditionals offered by Crupi and Iacona. As will be shown, in a first-order language that contains a naïve truth predicate and a suitable conditional, one can define a validity predicate in accordance with the thesis that the inference from a conjunction of premises to a conclusion is valid when the corresponding conditional is true.

  17. Certain and Uncertain Inference with Indicative Conditionals.Paul Égré, Lorenzo Rossi & Jan Sprenger - forthcoming - Australasian Journal of Philosophy.
    This paper develops a trivalent semantics for the truth conditions and the probability of the natural language indicative conditional. Our framework rests on trivalent truth conditions first proposed by Cooper (1968) and Belnap (1973) and it yields two logics of conditional reasoning: (i) a logic C of certainty-preserving inference; and (ii) a logic U for uncertain reasoning that preserves the probability of the premises. We show systematic correspondences between trivalent and probabilistic representations of inferences in either framework, and we use (...)

    The paper defends a variant of the material implication approach to the meaning of conditional sentences against some arguments that are considered to be widely subscribed to and/or important in the philosophical, psychological and linguistic literature. These arguments are shown to be wrong, debatable, or to miss their aim if the truth conditions defining material implication are viewed as determining nothing but the denotation of conditional sentences and if the function of conditional sentences in deduction (logic) is focused on rather (...)

  19. David Boonin on the Non-Identity Argument: Rejecting the Second Premise.Molly Gardner - 2019 - Law, Ethics and Philosophy 7:29-47.
    According to various “harm-based” approaches to the non-identity problem, an action that brings a particular child into existence can also harm that child, even if his or her life is worth living. In the third chapter of The Non-Identity Problem and the Ethics of Future People, David Boonin surveys a variety of harm-based approaches and argues that none of them are successful. In this paper I argue that his objections to these various approaches do not impugn a harm-based approach that (...)

    Gilabert argues that the humanist conception of duties of global justice and the principle of cosmopolitan justifiability will lead us to accept an egalitarian definition of individual autonomy. Gilabert further argues that realizing conditions of individual autonomy can serve as the cut-off point to duties of global justice. I investigate his idea of autonomy, arguing that in order to make sense of this claim, we need a concept of autonomy. I propose 4 possible definitions of autonomy, none of which seem (...)

  21. Carroll’s Regress Times Three.Gilbert Plumer - 2023 - Acta Analytica 38 (4):551-571.
    I show that in our theoretical representations of argument, vicious infinite regresses of self-reference may arise with respect to each of the three usual, informal criteria of argument cogency: the premises are to be relevant, sufficient, and acceptable. They arise needlessly, by confusing a cogency criterion with argument content. The three types of regress all are structurally similar to Lewis Carroll’s famous regress, which involves quantitative extravagance with no explanatory power. Most attention is devoted to the sufficiency criterion, including its (...)

  22. Triviality Results and the Relationship between Logical and Natural Languages.Justin Khoo & Matthew Mandelkern - 2019 - Mind 128 (510):485-526.
    Inquiry into the meaning of logical terms in natural language (‘and’, ‘or’, ‘not’, ‘if’) has generally proceeded along two dimensions. On the one hand, semantic theories aim to predict native speaker intuitions about the natural language sentences involving those logical terms. On the other hand, logical theories explore the formal properties of the translations of those terms into formal languages. Sometimes, these two lines of inquiry appear to be in tension: for instance, our best logical investigation into conditional connectives may (...)

    I argue against the skeptical epistemological view exemplified by the Groarkes that “all theories of informal argument must face the regress problem.” It is true that in our theoretical representations of reasoning, infinite regresses of self-justification regularly and inadvertently arise with respect to each of the RSA criteria for argument cogency (the premises are to be relevant, sufficient, and acceptable). But they arise needlessly, by confusing an RSA criterion with argument content, usually premise material.

    Although in some contexts the notions of an ordinary argument’s presumption, assumption, and presupposition appear to merge into the one concept of an implicit premise, there are important differences between these three notions. It is argued that assumption and presupposition, but not presumption, are basic logical notions. A presupposition of an argument is best understood as pertaining to a propositional element (a premise or the conclusion) e of the argument, such that the presupposition is a necessary condition for (...)

  25. Deontic Modals and Probability: One Theory to Rule Them All?Fabrizio Cariani - 2016 - In Nate Charlow & Matthew Chrisman (eds.), Deontic Modality. New York, NY: Oxford University Press.
    This paper motivates and develops a novel semantic framework for deontic modals. The framework is designed to shed light on two things: the relationship between deontic modals and substantive theories of practical rationality and the interaction of deontic modals with conditionals, epistemic modals and probability operators. I argue that, in order to model inferential connections between deontic modals and probability operators, we need more structure than is provided by classical intensional theories. In particular, we need probabilistic structure that interacts (...)

  26. How to Embed Epistemic Modals without Violating Modus Tollens.Joe Salerno - manuscript
    Epistemic modals in consequent place of indicative conditionals give rise to apparent counterexamples to Modus Ponens and Modus Tollens. Familiar assumptions of fa- miliar truth conditional theories of modality facilitate a prima facie explanation—viz., that the target cases harbor epistemic modal equivocations. However, these explana- tions go too far. For they foster other predictions of equivocation in places where in fact there are no equivocations. It is argued here that the key to the solution is to drop the assumption (...)

    Brogaard and Salerno (2008) argued that counter-examples to contraposition, strengthening the antecedent, and hypothetical syllogism involving subjunctive conditionals only seem to work because they involve a contextual fallacy where the context assumed in the premise(s) is illicitly shifted in the conclusion. To avoid such counter-examples they have proposed that the context must remain fixed when evaluating an argument for validity. That is the Brogaard-Salerno Stricture. Tristan Haze (2016), however, has recently objected that intuitively valid argumentative forms such as (...)

    There is a felt difference between following an argument to its conclusion and keeping up with an argument in your judgments while failing to see how its conclusion follows from its premises. In the first case there’s what I’m calling an inferential seeming, in the second case there isn’t. Inferential seemings exhibit a cluster of functional and normative characteristics whose integration in one mental state is puzzling. Several recent accounts of inferring suggest inferential seemings play a significant role in the (...)

    ABSTRACT Drawing inspiration from Fred Dretske, L. S. Carrier, John A.

We show that our sensitivity analysis handles numerous Gettier-type cases and lottery problems, blocks pathways leading to skepticism, and validates the (...)

    This paper offers an original argument for a Humean thesis about promising that generalises to the domain of normative powers. The Humean ‘natural unintelligibility’ thesis – prominently endorsed by Rawls, Hart, and Anscombe, and roundly rejected or forgotten by contemporary writers (conventionalists and non – conventionalists alike) – holds that a rational, suitably informed agent cannot so much as make a promise (much less a morally-binding promise) without exploiting conventional norms that confer promissory significance on act types (e.g., signing on (...)

    Freedom is often defined by the possibility of doing otherwise. The conditional interpretation of this possibility, advanced by Moore, maintains that to say that someone could have done otherwise is to say that someone would have done otherwise if she had decided to do so.

The present article presents a defense of this interpretation against the argument with which Lehrer purports to have refuted it. As used (...)

    The problem analysed in this paper is whether we can gain knowledge by using valid inferences, and how we can explain this process from a model-theoretic perspective.

I argue in this paper that valid inference has an epistemic significance, i.e., it can be used by an agent to (...)

    Abstract: The article presents and critically discusses Walton's (and Reed's and Macagno's) argument scheme approach to a theory of good argumentation. In particular, four characteristics of Walton's approach are presented: 1. It presents normative requirements for argumentation in the form of argument schemes, i.e. relatively concrete type descriptions. 2. These schemata are enthymematic, i.e. they omit some of the premises required by other approaches. 3. The actual argument schemes are usually supplemented by critical questions. 4. The method is inductive, bottom-up, (...)

    This paper offers a conditional defence of a minimalist theory of appropriation. The conclusion of its main argument is that, if people do enjoy a natural right to appropriate unappropriated resources, then that right is best understood as a derivative right that stems from a more fundamental natural right to self-preservation. If this conclusion is correct, then insofar as people have a natural right to appropriation, it is much more limited than it is usually assumed, as the minimalist theory places (...)

    This paper argues that a necessary condition on inferential knowledge is that one knows all the propositions that knowledge depends on. That is, I will argue in support of a principle I call the Knowledge from Knowledge principle: (KFK) S knows that p via inference or reasoning only if S knows all the propositions on which p depends. KFK meshes well with the natural idea that (at least with respect to deductively valid or induc- tively strong arguments) the epistemic status (...)

    Fichte argues that the conclusion of Kant’s transcendental deduction of the categories is correct yet lacks a crucial premise, given Kant’s admission that the metaphysical deduction locates an arbitrary origin for the categories. Fichte provides the missing premise by employing a new method: a genetic deduction of the categories from a first principle. Since Fichte claims to articulate the same view as Kant in a different, it is crucial to grasp genetic deduction in relation to the sorts of (...)

    Beyond moral fundamentalism.Steven Fesmire - 2024 - New York, NY, United States of America: Oxford University Press.
    Moral fundamentalism is the habit of acting as though one has access to the exclusively right way to diagnose problems, along with the single approvable practical solution to any particular problem. This approach causes us to oversimplify situations, neglect broader context, take refuge in dogmatic absolutes, ignore possibilities for finding common ground, assume privileged access to the right way to proceed, and shut off honest inquiry. In this way, moral fundamentalism-exacerbated by social media silos-also makes the worst of native impulses (...)

    Russell’s role in the controversy about the paradoxes of material implication is usually presented as a tale of how even the greatest minds can fall prey to basic conceptual confusions. Quine accused him of making a silly mistake in Principia Mathematica. He interpreted “if- then” as a version of “implies” and called it material implication. Quine’s accusation is that this decision involved a use-mention fallacy because the antecedent and consequent of “if-then” are used instead of being mentioned as the (...) and the conclusion of an implication relation. It was his opinion that the criticisms and alternatives to the material implication presented by C. I. Lewis and others would never be made in the first place if Russell simply called the Philonian construction “material conditional” instead of “material implication”. Quine’s interpretation of the topic became hugely influential if not universally accepted. This paper will present the following criticisms against this interpretation: (1) the notion of material implication does not involve a use-mention fallacy, since the components of “if-then” are mentioned and not used; (2) Quine’s belief that the components of “if-then” are used was motivated by a conditional-assertion view of conditionals that is widely controversial and faces numerous difficulties; (3) if anything, it was Quine who could be accused of fallacious reasoning: he ignored that in the assertion of a conditional is the whole proposition that is asserted and not its constituents; (4) the Philonian construction remains counter-intuitive even if it is called “material conditional”; (5) the Philonian construction is more plausible when it is interpreted as a material implication.

  44. Replacing truth.Kevin Scharp - 2007 - Inquiry: An Interdisciplinary Journal of Philosophy 50 (6):606 – 621.
    Of the dozens of purported solutions to the liar paradox published in the past fifty years, the vast majority are "traditional" in the sense that they reject one of the premises or inference rules that are used to derive the paradoxical conclusion. Over the years, however, several philosophers have developed an alternative to the traditional approaches; according to them, our very competence with the concept of truth leads us to accept that the reasoning used to derive the paradox is sound. (...)

  45. Why Extensional Evidence Matters.Matheus Silva - manuscript
    Intensional evidence is any reason to accept a proposition that is not the truth values of the proposition accepted or, if it is a complex proposition, is not the truth values of its propositional contents. Extensional evidence is non-intensional evidence. Someone can accept a complex proposition, but deny its logical consequences when her acceptance is based on intensional evidence, while the logical consequences of the proposition presuppose the acceptance of extensional evidence, e.g., she can refuse the logical consequence of a (...)

  46. (1 other version)Gratitude Is Only Fittingly Targeted Towards Agents.Marcus William Hunt - 2021 - Sophia (2):1-19.
    The paper argues that ‘All varieties of gratitude are only overall fitting when targeted towards agents,’ for instance that any variety of gratitude for the beautiful sunset is only overall fitting if a supernatural agent such as God exists. The first premise is that ‘Prepositional gratitude is overall fitting only when targeted towards agents.’ For this premise, intuitive judgments are offered. The second premise is that ‘Prepositional gratitude is the paradigmatic variety of gratitude.’ For this premise, (...)

  47. Are epistemic reasons normative?Benjamin Kiesewetter - 2021 - Noûs 56 (3):670-695.
    According to a widely held view, epistemic reasons are normative reasons for belief – much like prudential or moral reasons are normative reasons for action. In recent years, however, an increasing number of authors have questioned the assumption that epistemic reasons are normative. In this article, I discuss an important challenge for anti-normativism about epistemic reasons and present a number of arguments in support of normativism. The challenge for anti-normativism is to say what kind of reasons epistemic reasons are if (...)

  48. The Parallel Manipulation Argument.Taylor W. Cyr - 2016 - Ethics 126 (4):1075-1089.
    Matt King has recently argued that the manipulation argument against compatibilism does not succeed by employing a dilemma: either the argument infelicitously relies on incompatibilist sourcehood conditions, or the proponent of the argument leaves a premise of the argument undefended. This article develops a reply to King’s dilemma by showing that incompatibilists can accept its second horn. Key to King’s argument for the second horn’s being problematic is “the parallel manipulation argument.” I argue that King’s use of this argument (...)

  49. There Is No Knowledge From Falsehood.Ian Schnee - 2015 - Episteme 12 (1):53-74.
    A growing number of authors defend putative examples of knowledge from falsehood (KFF), inferential knowledge based in a critical or essential way on false premises, and they argue that KFF has important implications for many areas of epistemology (whether evidence can be false, the Gettier debate, defeasibility theories of knowledge, etc.). I argue, however, that there is no KFF, because in any supposed example either the falsehood does not contribute to the knowledge or the subject lacks knowledge. In particular, I (...)

  50. Judgment aggregation: (Im)possibility theorems.Franz Dietrich - 2006 - Journal of Economic Theory 1 (126):286-298.
    The aggregation of individual judgments over interrelated propositions is a newly arising field of social choice theory. I introduce several independence conditions on judgment aggregation rules, each of which protects against a specific type of manipulation by agenda setters or voters. I derive impossibility theorems whereby these independence conditions are incompatible with certain minimal requirements. Unlike earlier impossibility results, the main result here holds for any (non-trivial) agenda. However, independence conditions arguably undermine the logical structure of judgment aggregation. I therefore (...)
