The essays in Logos and Life, the earliest written in 2001 but mainly dating from 2014 and later, cover topics in philosophy of mind, philosophy of action, ethics and philosophy of language. There are discussions of the voluntary and the involuntary; reasons for action; the idea of an 'inner state'; pleasure; the nature of ethics; justice; necessity and possibility; and a number of other topics. Numerous strands connect these four areas, which Roger Teichmann highlights: in this sense the collection exhibits thematic unity as well as diversity.
Several of the essays take as their starting points the ideas and philosophical methods of Wittgenstein and of Elizabeth Anscombe, and so will be of interest to anyone studying those philosophers. Anscombe was a friend and pupil of Wittgenstein, and Teichmann was fortunate enough to be a friend and pupil of Anscombe. He is now a leading authority on her philosophy.
A newly written Introduction serves to indicate the main themes and arguments of the book and provide an overall statement of Teichmann's philosophy.
