Are some people naturally brave? Can people be trained to be courageous? Can fears be acquired indirectly? Why is fear sometimes out of all proportion to the actual danger? When and why do fears return? What is panic, and how can it be prevented? In this edition, S.J. Rachman examines the nature of fear and courage in light of recent studies on the varieties of fear, how fears are acquired, and how they can be successfully treated, as well as on clinical expressions of courage.
