An important study area consists of injuries or diseases that destroy specific brain structures; these clinical events are often closely correlated to nuanced effects on selective aspects of consciousness. Professor Damasio's book makes good use of these data to describe many known neural correlates of consciousness. For purposes of this book, he adopts the working hypothesis that mental states and brain states are essentially equivalent. While many (including this reviewer) find this idea questionable, such tentative hypothesis is quite appropriate for a book of this kind. In science we often adopt useful, if highly oversimplified, models in the early stages of our studies with no illusions that they are perfectly accurate. In this manner "Truth" is (hopefully) approached in a series of successive approximations. Thankfully, Damasio does not claim to "explain" consciousness.

The book's title is based on Damasio's suggestion that our evolutionary history reveals many simple creatures with active "minds" (defined broadly), but only much later did self (awareness) develop; in other words the human self is built in steps grounded in the so-called "protoself." An essential step is the development of homeostatis (life regulation needed to survive) in single cell creatures like bacteria, followed by progressively more complex "societies of cells" in more complex creatures like insects, reptiles, and mammals. Thus consciousness, rooted in our evolutionary past, helps to optimize our responses to the environment so that we may continue our existence. Damasio also describes the self in terms of stages: the protoself, core self and autobiographical self, along with specific brain structures that may support these distinct stages.
