    Maher proposed in 1974 that schizophrenic delusions are hypotheses formed to explain anomalous experiences. He stated that they are “rational, given the intensity of the experiences that they are developed to explain.” Two-factor theorists of delusion criticized Maher’s theory because 1) it does not explain why some patients with anomalous experiences do not develop delusions, and 2) adopting and adhering to delusional hypotheses is irrational, considering the totality of experiences and patient…Read more

    Conventions and Failure of Communication
    Kagaku Tetsugaku 43 (1): 1-14. 2010.
    D. Davidson argued that shared conventions learned in advance are not essential for the success of communication. In this paper, holding the validity of his contention in suspense, I argue that linguistic conventions play essential roles when communication fails. In everyday communication, when discrepancies are detected between what the speaker intended to inform the hearer and what the hearer actually understood, it becomes necessary to determine whether the speaker or the hearer caused the co…Read more

    Just as sadness is not always a symptom of mood disorder, irrational beliefs are not always symptoms of illness. Pathological irrational beliefs are distinguished from non-pathological ones by considering whether their existence is best explained by assuming some underlying dysfunctions. The features from which to infer the pathological nature of irrational beliefs are: un-understandability of their progression; uniqueness; coexistence with other psycho-physiological disturbances and/or concurre…Read more

    Incarnating Kripke's Skepticism About Meaning
    Erkenntnis 78 (2): 277-291. 2013.
    Although Kripke’s skepticism leads to the conclusion that meaning does not exist, his argument relies upon the supposition that more than one interpretation of words is consistent with linguistic evidence. Relying solely on metaphors, he assumes that there is a multiplicity of possible interpretations without providing any strict proof. In his book The Taming of the True, Neil Tennant pointed out that there are serious obstacles to this thesis and concluded that the skeptic’s nonstandard interpr…Read more
