  1. Gemma Robles (2008). Extensions of the Basic Constructive Logic for Weak Consistency BKc1 Defined with a Falsity Constant. Logic and Logical Philosophy 16 (4):311-322.
    The logic BKc1 is the basic constructive logic for weak consistency in the ternary relational semantics without a set of designated points. In this paper, a number of extensions of B Kc1 defined with a propositional falsity constant are defined. It is also proved that weak consistency is not equivalent to negation-consistency or absolute consistency in any logic included in positive contractionless intermediate logic LC plus the constructive negation of BKc1 and the contraposition axioms.

  2. Yaroslav Shramko (2012). What is a Genuine Intuitionistic Notion of Falsity? Logic and Logical Philosophy 21 (1):3-23.
    I highlight the importance of the notion of falsity for a semantical consideration of intuitionistic logic. One can find two principal (and non-equivalent) versions of such a notion in the literature, namely, falsity as non-truth and falsity as truth of a negative proposition. I argue in favor of the first version as the genuine intuitionistic notion of falsity.

    Descartes’ accounts of sensory perception have long troubled his interpreters, for their lack of clear and explicit statements on some fundamental issues. His readers have wondered whether he allows spatial sensory ideas (spatial qualia); whether sensory ideas such as color or pain are representations and, if so, what they represent; and what cognitive value Descartes attributed to sense perception. Recent discussions take differing stands on the questions just mentioned, and also disagree over Descartes’ account of the externalization of sensory qualities, (...)

    Heinrich Wansing (2012). A Non-Inferentialist, Anti-Realistic Conception of Logical Truth and Falsity. Topoi 31 (1):93-100.
    Anti-realistic conceptions of truth and falsity are usually epistemic or inferentialist. Truth is regarded as knowability, or provability, or warranted assertability, and the falsity of a statement or formula is identified with the truth of its negation. In this paper, a non-inferentialist but nevertheless anti-realistic conception of logical truth and falsity is developed. According to this conception, a formula (or a declarative sentence) A is logically true if and only if no matter what is told about what (...)

    Cecilia Wee (2006). Material Falsity and Error in Descartes' Meditations. Routledge.
    Material Falsity and Error in Descartes' Meditations approaches Descartes' Meditations as an intellectual journey, wherein Descartes' views develop and change as he makes new discoveries about self, God and matter. The first book to focus closely on Descartes' notion of material falsity, it shows how Descartes' account of material falsity and correspondingly his account of crucial notions such as truth, falsehood and error evolves according to the epistemic advances in the Meditations. It also offers important new insights (...)

I explain and critique DeRose's reasons for proposing this modification to contextualist methodology, drawing on recent experimental studies of DeRose's bank cases as well as experimental findings about the verification of affirmative and negative statements. While DeRose's arguments for his particular modification to contextualist methodology fail, the lesson of his proposal is that there is (...)

    We present $\in_I$-Logic (Epsilon-I-Logic), a non-Fregean intuitionistic logic with a truth predicate and a falsity predicate as intuitionistic negation. $\in_I$ is an extension and intuitionistic generalization of the classical logic $\in_T$ (without quantifiers) designed by Sträter as a theory of truth with propositional self-reference. The intensional semantics of $\in_T$ offers a new solution to semantic paradoxes. In the present paper we introduce an intuitionistic semantics and study some semantic notions in this broader context. Also we enrich the quantifier-free language (...)

    Descartes claims in the Third Meditation that ideas of sense might be materially false. While an accurate interpretation of this claim has the potential of providing some valuable insights into Descartes's theory of ideas in general and his understanding of the epistemic status of sensations in particular, the explanation Descartes provides of the material falsity of ideas is itself obscure and misleading, making accurate interpretation difficult. In this paper an interpretation of material falsity is offered which identifies the (...)

  11. Timothy Williamson (2000). Truth, Falsity, and Borderline Cases. Philosophical Topics 28 (1):211-244.
    According to the principle of bivalence, truth and falsity are jointly exhaustive and mutually exclusive options for a statement. It is either true or false, and not both, even in a borderline case. That highly controversial claim is central to the epistemic theory of vagueness, which holds that borderline cases are distinguished by a special kind of obstacle to knowing the truth-value of the statement. But this paper is not a defence of the epistemic theory. If bivalence holds, it (...)

    We give a procedure to obtain falsity conditions for IF-sentences, using Skolemization. The expressive power of an IF-sentence can then be strongly captured by a pair of Σ11-sentences1. A result from [Burgess 2003] shows that, conversely, any pair of incompatible Σ11-sentences corresponds with an IF-sentence. In the second part, we reflect on the influence of the order of the steps in the Skolemization procedures for IF-logic. We also reflect on the nature of game theoretical negation.

    Dan López de Sa (2009). Can One Get Bivalence From (Tarskian) Truth and Falsity? Canadian Journal of Philosophy 39 (2):273-282.
    Timothy Williamson famously offered an argument from these Tarskian principles in favor of bivalence. I show, dwelling on (Andjelkovic & Williamson, 2000), that the argument depends on a contentious formulation of the Tarskian principles about truth (and falsity), which the supervaluationist can reject without jeopardizing the Tarskian insight. In the mentioned paper, Adjelkovic and Williamson argue that, even if the appropriate formulation seems to make room for failure of bivalence in borderline cases, this appearance is illusory, once one grants (...)

    Claudia Lorena Garcia (1999). Transparency and Falsity in Descartes's Theory of Ideas. International Journal of Philosophical Studies 7 (3):349 – 372.
    Here I develop an interpretation of Descartes' theory of ideas which differs from the standard reading in that it incorporates a distinction between what an idea appears to represent and what it represents. I argue that this interpretation not only finds support in the texts but also is required to explain a large number of assertions in Descartes which would otherwise appear irremediably obscure or problematic. For example, in my interpretation it is not puzzling that Descartes responds to Arnauld's difficulty (...)

    This paper aims to establish three major theses: (1) Not only declarative sentences, but also interrogatives and imperatives, may be classified as true or as false. (2) Declarative, imperative, and interrogative utterances may also be classified as honest or as dishonest. (3) Whether an utterance is honest or dishonest is logically independent of whether it is true or is false. The establishment of the above theses follows upon the adoption of a principle for identifying what is meant by any sentence, (...)

    The logic BKc6 is the basic constructive logic in the ternary relational semantics adequate to consistency understood as absolute consistency, i.e., non-triviality. Negation is introduced in BKc6 with a negation connective. The aim of this paper is to define the logic BKc6F. In this logic negation is introduced via a propositional falsity constant. We prove that BKc6 and BKc6F are definitionally equivalent. Then, we show how to extend BKc6F within the spectrum of logics delimited by contractionless intuitionistic logic. All (...)

    In Metaphysics Delta 29 Aristotle distinguishes three classes of falsity and three corresponding senses of the ‘false’. The paper examines Aristotle’s arguments from a close-reading perspective, and analyses the meaning of false ‘as a thing’ , the significance of Aristotle’s dispute with Antisthenes on the subject of contradiction and verbal falsehood, and Aristotle’s conception of the false person. By paying attention to the precise order of Aristotle’s presentation, the paper raises the question about the manner in which the three (...)

    Although there is a massive amount of work on truth, there is very little work on falsity. Most philosophers probably think this is appropriate; after all, once we have a solid understanding of truth, falsity should not prove to be much of a challenge. However, there are several interesting and difficult issues associated with understanding falsity. After considering two prominent definitions of falsity and presenting objections to each one, I propose a definition that avoids their problems.

    In this essay I show how Nietzsche's use of metaphor in "Truth and Falsity in an Ultra-Moral Sense" helps make the general point of the essay itself. I argue that the essay both distinguishes between the human and the natural order and yet works to erase that distinction, just as it both posits and denies a difference between truth and lie, dream and reality. Given that Nietzsche's text is directed against the possibility of literal truth, I argue that by (...)

Moreover, dealing with fakes also means going beyond rigid disciplinary boundaries. Indeed, the editors (...)

We provide a simple proof of Friedman’s Theorem that finitely axiomatized, sequential, consistent theories are trustworthy. We provide an example of a theory whose schematic predicate logic is complete Π20.

    The Fitzgerald-Lorentz contraction hypothesis, proposed as an explanation of the Michelson-Morley result, fails to account for the Kennedy-Thorndike result. Hence, Grünbaum argues, the hypothesis has been falsified. However, the contraction hypothesis as formulated by Lorentz is false for the very fundamental reason that it entails a contradiction, namely, the consequence that light waves must have a variable velocity along what by definition is taken to be a rest length. Furthermore, the attempt to resolve this contradiction by coupling the Fitzgerald-Lorentz contraction (...)

    Participants in the debate about whether simplicity is a guide to truth or merely pragmatically useful typically wrangle over two problems: (1) how to weigh simplicity against other virtues like strength and fitness and (2) whether there is a unique measure for simplicity that straps it to truth. I would like to put forth a third problem: (3) Even if problems (1) and (2) could be solved, it is far from clear whether the simplest theory out of an available class (...)
