    On the Arithmetical Truth of Self‐Referential Sentences.Kaave Lajevardi & Saeed Salehi - 2019 - Theoria 85 (1):8-17.
    We take an argument of Gödel's from his ground‐breaking 1931 paper, generalize it, and examine its validity. The argument in question is this: "the sentence G says about itself that it is not provable, and G is indeed not provable; therefore, G is true".

  2. Laws and Counterfactuals: Defusing an Argument Against the Humean View of Laws.Kaave Lajevardi - 2011 - Dialogue 50 (4):751-758.
    ABSTRACT: Appealing to the failure of counterfactual support is a standard device in refuting a Humean view on laws of nature: some true generalisations do not support relevant counterfactuals; therefore not every true general fact is a law of nature—so goes the refutation. I will argue that this strategy does not work, for our understanding of the truth-value of any counterfactual is grounded in our understanding of the lawhood of some statements related to it.

  3. Kripke and the Dogmatism Paradox.Kaave Lajevardi - manuscript
    I aim at dissolving Kripke's dogmatism paradox by arguing that, with respect to any particular proposition p which is known by a subject A, it is not irrational for A to ignore all evidence against p. Along the way, I offer a definition of 'A is dogmatic with respect to p', and make a distinction between an objective and a subjective sense of 'should' in the statement 'A should ignore all the evidence against p'. For the most part, I deal (...)

  4. Transworld Identity as a Problem for Essentialism About Kinds.Kaave Lajevardi - manuscript
    Essentialism about natural kinds involves talking about kinds across possible worlds. I argue that there is a non-trivial transworld identity problem here, which cannot be (dis)solved in the same way that Kripke treats the corresponding transworld identity problem for individuals. -/- I will briefly discuss some ideas for a solution. The upshot is scepticism concerning natural-kind essentialism.

    There May Be Many Arithmetical Gödel Sentences.Kaave Lajevardi & Saeed Salehi - forthcoming - Philosophia Mathematica:nkaa041.
    We argue that, under the usual assumptions for sufficiently strong arithmetical theories that are subject to Gödel’s First Incompleteness Theorem, one cannot, without impropriety, talk about *the* Gödel sentence of the theory. The reason is that, without violating the requirements of Gödel’s theorem, there could be a true sentence and a false one each of which is provably equivalent to its own unprovability in the theory if the theory is unsound.

    What He Could Have Said (but Did Not Say) About Gödel’s Second Theorem: A Note on Floyd-Putnam’s Wittgenstein.Kaave Lajevardi - 2021 - Wittgenstein-Studien 12 (1):121-129.
    In several publications, Juliet Floyd and Hilary Putnam have argued that the so-called ‘notorious paragraph’ of the Remarks on the Foundations of Mathematics contains a valuable philosophical insight about Gödel’s informal proof of the first incompleteness theorem – in a nutshell, the idea they attribute to Wittgenstein is that if the Gödel sentence of a system is refutable, then, because of the resulting ω-inconsistency of the system, we should give up the translation of Gödel’s sentence by the English sentence “I (...)
