The book sheds an interesting new light on interpretations of Ludwig Wittgenstein's philosophy as it offers one of the first explorations of his concepts between the Tractatus and the Philosophical Investigations. The author argues that, rather than developing in a linear sequence from insight to insight and from idea to idea, Wittgenstein's thought in the middle period expands radially, unfolding in several directions at the same time. A must-read for Wittgenstein researchers, the book is certainly of profound interest to humanities scholars and social scientists alike.

This book offers broad hermeneutic explanations of Wittgenstein's writings from 1929 to 1936. They are based on a thorough knowledge of the source material, which they place in the context of his thought and its philosophical environment. I am impressed with the scientific merit of the present work.
