Overall Johnston has done a phenomenal job and this book should be required reading for all those interested in behavior.
It is quite striking that although W’s observations are fundamental to all study of behavior—linguistics, philosophy, psychology, history, anthropology, politics, sociology, and art, he is not even mentioned in most books and articles, with even the exceptions having little to say, and most of that distorted or flat wrong. There is a flurry of recent interest, at least in philosophy, and possibly this preposterous situation will change, especially due to the continuing efforts of Peter Hacker, Daniele Moyal-Sharrock and more recently Annalisa Coliva. I will first offer some comments on philosophy (descriptive psychology) and its relationship to contemporary psychological research as exemplified in the works of Searle (S) and Wittgenstein from the modern two systems of thought perspective as W did 60 years ago.
Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).
