This book investigates the fundamental question of how human thought and language establish a connection with the objective reality of the world. Charles Travis, a distinguished philosopher, utilizes his expertise in the philosophy of language and mind to provide a rigorous analysis of Ludwig Wittgenstein's Philosophical Investigations. By examining the relationship between propositional content and the state of affairs in the world, Travis constructs a unified interpretation of Wittgenstein's later work that challenges traditional representationalist views.

Scholars and students of analytic philosophy frequently cite this work as a significant contribution to the study of Wittgensteinian thought. Readers often note the high level of academic density and the sophisticated nature of the arguments presented throughout the text.
