 George Herbert Mead (1863–1931), American philosopher and social theorist, is often classed with William James, Charles Sanders Peirce, and John Dewey as one of the most significant figures in classical American pragmatism. Dewey referred to Mead as “a seminal mind of the very first order” (Dewey, 1932, xl). Yet by the middle of the twentieth-century, Mead’s prestige was greatest outside of professional philosophical circles. He is considered by many to be the father of the school of Symbolic Interactionism in sociology and social psychology, although he did not use this nomenclature. Perhaps Mead’s principal influence in philosophical circles occurred as a result of his friendship with John Dewey. There is little question that Mead and Dewey had an enduring influence on each other, with Mead contributing an original theory of the development of the self through communication. This theory has in recent years played a central role in the work of Jürgen Habermas. While Mead is best known for his work on the nature of the self and intersubjectivity, he also developed a theory of action, and a metaphysics or philosophy of nature that emphasizes emergence and temporality, in which the past and future are viewed through the lens of the present. Although the extent of Mead’s reach is considerable, he never published a monograph in philosophy. His most famous work, Mind, Self, and Society: From the Standpoint of a Social Behaviorist, was published after his death and is a compilation of student notes and selections from unpublished manuscripts.
