This book opens with a resounding question: 'Who are we?' The many pages that follow, highly entertaining and richly informed as they are, never directly answer this question. Instead, they answer another question: 'Who or what do we think we are?' Perhaps the choice of the plural form - 'Who are we?' rather than 'Who am I?' - already betrays the fact that the writer has the mind of a historian, since it assumes the existence of a social object of investigation, rather than the mind of a philosopher, who would assume as little as possible. Imagine how different it would have been if Descartes had written: 'We think, therefore we are.' Roy Porter tells the story of evolving conceptions of human nature in the Enlightenment. The basic answer offered to the unstated second question is: 'Living as we do in an originally Christian culture, we see ourselves as a mixture of flesh and spirit.' The word 'mixture' can be unpacked in various ways, as we gradually learn. Porter, who knows all about 18th-century medicine, naturally chooses to lay his emphasis on the part played in the story by flesh.
