Abstract

This is a most helpful survey of the rise and development of a new attitude towards philosophical investigation among a number of influential thinkers in England. The prime movers in this “revolution in philosophy” have been mathematicians, like Russell, logicians, like Ramsey and Wisdom, professors of philosophy, such as Ayer and Ryle; they have all felt the massive influence of Wittgenstein, and they make use of symbolic logic as an instrument. A movement which, in origin, was concerned especially with mathematics and logic, and soon became an attempt to work out a perfect language, and, from an assumed empiricism, to use the structure of language to reveal the structure of reality, was bound to be highly technical and to give rise to many divergent theories as various obstacles to this ambitious programme were met with. Moreover, many of the more notable contributions of these thinkers are found in books that are intelligible only to one acquainted with symbolic logic, or in articles in specialized reviews that are not easily accessible to all. The movement has already passed through two well-defined phases, and has now entered on another. The time is thus ripe for such a book as this which traces, in a language which all can follow, the course of development, and the reasons for it, within this tendency, and introduces us to the present state of investigation and the main lines along which such investigation is proceeding.
