The Foundation Stone of Psychology and Philosophy--A Critical Review of 'On Certainty' by Ludwig Wittgenstein (1969) (1951). (review revised 2019)

A critical review of Wittgenstein's 'On Certainty' which he wrote in 1950-51 and was first published in 1969. Most of the review is spent presenting a modern framework for philosophy (the descriptive psychology of higher order thought) and positioning the work of Wittgenstein and John Searle in this framework and relative to the work of others. It is suggested that this book can be regarded as the foundation stone of psychology and philosophy as it was the first to describe the two systems of thought and shows how our unshakable grasp of the world derives from our innate axiomatic System 1, and how this interacts with System 2. It was a revolution in epistemology since it showed that our actions rest not on judgements but on innate undoubtable axioms leading directly to action. I situate the work of Wittgenstein and Searle in the framework of the two systems of thought prominent in thinking and decision research, employing a new table of intentionality and new dual systems nomenclature. 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).
