Given that Schutz was a philosopher and a social scientist, this book will examine topics in Schutz’s philosophical-phenomenological theory of the social world, such as the second person, the face-to-face relationship, the meaning of human action, signs, symbols, relevance (or interests). Schutz’s explanation of the social world, however, was meant to provide a philosophical foundation for the social sciences, and so this book will also consider epistemological questions, such as traditional knowledge and the opacity of knowledge and theory, that is, the neglected or unseen questions that accompany knowing or theorizing. Also, authors from within the Schutzian framework will address issues within the social sciences, such as the Durkheimian aspects of Schutz’s thought, the sociology of knowledge, and the theory of sociology. It will also explore how Schutzian theory, which is often viewed as a micro-sociology, can be extended to give an account of a macro-sociological reality like modern society (Gesellschaft)
