The concept of 'having a mind' is one of the key concepts that we use to carve a division of extreme significance into the universe. We say that parts of the universe 'have a mind' and that parts of the universe do not 'have a mind'. But what exactly is a mind? In this book John King claims that to have a mind is to think; this may seem obvious. But on route to this conclusion he discards a multitude of views concerning the mental - that 'having a mind' is to do with freedom, or awareness, or intentionality, or perception, or feeling states, or the inner cause of certain movements, or a 'central core' of these attributes. This analysis is sure to help the reader clarify their own beliefs about what a mind is.
