ABSTRACT
Each year the Royal College of Psychiatrists arranges a lecture to be given in honour of Henry Maudsley, who was a benefactor of the College’s predecessor, the Royal Medico-Psychological Association (and also of the Maudsley Hospital). I was invited to give the 1976 lecture at the meeting of the College held in London during the autumn. It was published in much amplified form and in two parts the following spring.
