A Ratiocinative Assessment of A.J. Ayer's Rejection of Metaphysics

Purpose: This paper aims at exposing and appraising the arguments of A.J. Ayer against metaphysics, as reflected in the first chapter of his book, Language, Truth and Logic. It shall explore the basic assumptions, content and concerns of the metaphysical enterprise, and place them in careful juxtaposition with A.J. Ayer's positivist assumptions in order to discover whether the claims he makes regarding metaphysics are really valid or not. The conclusion will emphasize the relevance and irrefutability of metaphysics. Methodology: The work is expository, analytic, critical and evaluative, in its methodology. Findings: Sir Alfred Julius Ayer was an English philosopher who developed key features of logical positivism. His book Language, Truth, and Logic (1936) is one of the most influential philosophy books in the 20th century, addressing questions of reality, perception, knowledge and meaning. In it Ayer explains important positivist ideas, like the principle of verifiability as a criterion of meaning, the rejection of metaphysics, and the emotivist theory of ethics. In Ayer's logical empiricism, philosophy is no longer seen as a metaphysical concern, nor as an attempt to provide speculative truths about the nature of ultimate reality. Instead, philosophy is seen as an activity of defining and clarifying the logical relationships of empirical propositions. Unique Contribution to theory, practice and policy (recommendation): The ratiocinative discussion of A. J. Ayer's rejection of Metaphysics, offers an alternative perspective on how Metaphysics should be construed, given its centrality to, and in-eliminability in philosophical discourses.
