    According to a bedrock assumption in the current methodology of armchair philosophy, we may refute a theory aiming at analyzing a concept by providing a counterexample in which it intuitively seems that a hypothetical or real situation does not fit with what the theory implies. In this paper, we shall argue that this assumption is at most either untenable or otherwise useless in bringing about what is commonly expected from it.

    Logical Pluralism: Where the Conflict Really Lies
    Wisdom and Philosophy. forthcoming.
    Recent years have seen a surge of attention to the problem of logical pluralism; most of which has been a reaction to Beall and Restall’s account of logical pluralism as the existence of more than one equally correct semantic relation of logical consequence. The underlying thesis is that the indeterminacy of the notion of validity goes beyond what the inductive-deductive distinction can precisify. The notion of deductive validity itself is indeterminate as well and this indeterminacy has its roo…Read more

    Some analogous higher-order versions of Skolem’s paradox will be introduced. The generalizability of two solutions for Skolem’s paradox will be assessed: the course-book approach and Bays’ one. Bays’ solution to Skolem’s paradox, unlike the course-book solution, can be generalized to solve the higher-order paradoxes without any implication about the possibility or order of a language in which mathematical practice is to be formalized.

    Quantifier Variance Without Meaning Variance
    Axiomathes 30 (3): 313-325. 2020.
    Quantifier variance entails that ‘there exists’ has a variety of meanings. Determining what makes all these meanings quantifier meanings is a problem associated with this view. A reasonable candidate suggested by Hirsch is the set of formal rules governing quantification. However, the collapse argument presents a notorious objection to the viability of the candidate: there cannot be more than one quantifier obeying the same rules up to logical equivalence. It is proposed that a quantifier varian…Read more

    Perception, self-correction and philosophical intuition
    with Peyman Pourghannad and Lotfollah Nabavi
    Metaphysik 8 (22): 47-60. 2016.
    According to the dominant methodology of contemporary analytic philosophy, philosophical intuitions play evidential roles for or against philosophical theories. However, intuitions can play the supposed role successfully only if they are justified. Phenomenalism, as one of the proposed theories that aims to explain and argue for justifiedness of intuitions, claims that intuitions are justified because they have a certain phenomenal character: Intuitive contents seem to be true. Furthermore, it a…Read more

    Russell once said that “Vagueness and precision alike are characteristics which can only belong to a representation, of which language is an example. They have to do with the relation between a representation and that which it represents. Apart from representation, whether cognitive or mechanical, there can be no such thing as vagueness or precision; things are what they are, and there is an end of it” (1923). In other words, expressions like ontological vagueness (and even ontological precision…Read more

    According to a common definition, the argument of truthful ones is an argument in which the existence of Necessary Being is proved with no presumption of the existence of the possible being. Avicenna proposed different versions of this style of argument and the version in the book of Nejat is one of them. This paper is intended to examine the possibility of proving the logical validity of this version in first-order predicate logic and explain the principles which the argument is based on. In th…Read more

    Simple-If Question and Essence’s Being Existent; Mullā Sadrā v.s. Mīr Dāmād
    Journal of Philosophical Investigations 12 (25): 95-111. 2019.
    Mīr Dāmād, in Qabasāt argues that existence cannot be a real property for essences. If existence, he argues, were a real property of an essence, there would remain no distinction between simple-if and compound-if questions. It is well-known that Mullā Sadrā has given three different accounts in order to explain essence’s being existent: first that existence is an analytical property for essence; second that none of existence or essence is a property of the other one; and third that essence is a …Read more
