The position Melser defends… flouts all received doctrine in philosophy of mind and cognitive psychology… it is entirely original, and his case for it highly so. He argues that all… mental talk is metaphorical, and even provides an illuminating general essay on metaphor to back up that claim. An extraordinary work, and well argued too.

The Act of Thinking is... ...the work of a mature, sophisticated and profound thinker who may just have written the most original and important book in philosophy of mind to have appeared in over a decade illuminating work that provides exciting new insights into some old philosophical puzzles impressive piece of philosophy.

The Act of Thinking is a pivotal book and a significant contribution to the ‘second cognitive revolution.’

Andy Lock, Professor of Psychology, Massey University, New Zealand.

It is Derek Melser's claim that we learn not only how to think but also how to be conscious beings – …he develops an account of thinking and consciousness that connects them with readily identifiable acts occurring in our collective world. This important book indicates… a whole new social direction for cognitive and consciousness studies.

John Shotter, Professor Emeritus of Communication, University of New Hampshire

Melser’s book is a fascinating read because it is the product of a lively sense of direction – a genuine book of philosophy which never once strays from the path of explaining how we think and how we are conscious.

The late Peter Munz (Professor Emeritus of History, Victoria University of Wellington, and author of Beyond Wittgenstein’s Poker) in New Zealand Books.

This is a book that challenges the current orthodoxy, both in the philosophy of mind and in the cognitive sciences, that thinking (construed broadly to include perceiving, imagining, remembering, etc.) is a mental process in the head.

Robert A. Wilson (Philosophy Dept., University of Alberta) in Notre Dame Philosophical Review.

A genuinely new account of the nature of thought… which draws on and transcends the work of Ryle, Vygotsky, Hampshire, and more recent developmental theory. Melser does not explore developmental psychopathology, but provides an excellent framework for anyone wishing to do so.

Dr Richard Gipps on the International Network of Philosophy and Psychiatry website.

Derek Melser’s The Act of Thinking is a fascinating account of what thinking might be… his arguments against a brute, uncritically biological explanation of actions, against the description of thinking and acting as processes “going on in the brain” remain formidable… they cannot easily be ignored by philosophers and cognitive scientists.

Marek McGann (Mary Immaculate College, University of Limerick) in International Journal of Philosophical Studies.

I highly recommend The Act of Thinking as a challenging, subtle, eloquent, plainspoken, amicable, contemporary discussion of the philosophy of mind.

This is a very fine book, partly because I concur with your theory of mind so completely, partly because you’ve argued the case for deconstructing the false antinomies of speech versus gesture, res cogitans versus res extensa, emotion versus thought, conception versus action so consummately.

Finally, I got chance to finish your book. It is a stunning accomplishment! I really enjoyed reading it and think that you are entirely on the right track in your thinking about thinking. I particularly appreciated the originality of your writing (as a form of thinking) and the care with which you develop and integrate the writings (“the thoughts”) of others. The book is marked by a care that can only be described as loving. Thank you.
