Our psychology list aims to focus on the big thinkers behind psychology, psychoanalysis and psychotherapy. The big thinkers here have focused on the human mind, so we thought it only fair to examine their lives and worlds – to learn more about their minds – before looking at their thoughts on how the rest of us think.

Trying to understand how the human mind works is never going to be an easy task, and studying the works of these great thinkers in their own words is often an uphill struggle. So our authors have taken it upon themselves to flesh out the inner and outer worlds of these psychological thinkers before examining their ideas in crystal-clear language.

Ideas don't exist in a vacuum. As with all our subjects in the Who the Hell is? series, Psychology embraces the other topics and in turn takes part in a fascinating global conversation, made truly alive and accessible for the first time.
