The Life of the Mind presents an original and striking conception of the mind and its place in nature. In a spirited and rigorous attack on most of the orthodox positions in contemporary philosophy of mind, McCulloch connects three of the orthodoxy's central themes - externalism, phenomenology and the relation between science and common-sense psychology - in a defence of a throughly anti-Cartesian conception of mental life.

McCulloch argues that the life of the mind will never be understood until we properly understand the subject's essential embodiment and immersion in the world, until we give up the idea that intentionality and phenomenology must be understood separately. The product of over twenty years' thinking on these issues, McCulloch's book is a bold and significant contribution to philosophy.
