Ayer’s Theory of Emotivism 107 120 1720 10.22091/jptr.2020.5538.2327 FA Mohsen Shiravand Ph.D. Assistant prof. of Ethics, University of Isfahan, Iran. 0000-0001-6746-5791 Journal Article 2020 05 15 No doubt, Gottlob Frege and A. J. Ayer are considered to be among the most prominent contemporary philosophers. Insofar as one of them has revolutionized the linguistic domain while the other has influenced the domain of ethics in a diametrical fashion. Ayer’s theory of emotivism is regarded as one of the most controversial moral theories in the past century. We believe that Frege, as a linguistic philosopher, has influenced emotivism in the methodological, logical, semantic, and epistemological domains. The emphasis on two fundamental principles of “compositionality” and “contextuality”; “the existence of mathematical concepts independent from mind”, “empiricism and verificationism” are all variables upon which emotivism is clearly dependent. The latter claim can be substantiated via analysis of the works of Ayer and particularly his “Language, Truth, and Logic” as well as his assertion in the introduction to this book concerning his debt to Frege. Among the most significant results of this essay, one can refer to the demonstration of the point that what constitutes the identity of the theory of emotivism is influenced by the “general line of linguistic analysis” in the aforementioned four domains.
