Rear-view mirrors are not normal scientific equipment, nor are philosophers all that keen to recall a partly embarrassing past. But looking back can cure a self-induced narrowing of the modern scientific mind and help us to renew a sense of where, if anywhere, we might feel we belong in the world.

Today, a centuries-long belief in the primacy of a first-personal perspective has given way to an opposite view that what passes through the conscious mind has little to do with who we are and what we are doing. A lifelong campaigner for the first-personal perspective, Alastair Hannay presents here a powerful and historically framed case for restoring faith in its status as a provider of important truths about ourselves.
