Alex Comfort was a British poet, novelist, biologist, cultural critic, activist, and anarchist, and the author of the international bestseller, The Joy of Sex. He played a vital role in making gerontology (the study of aging) a viable branch of modern science, energizing the direct-action movement for nuclear disarmament, revitalizing anarchism as a political philosophy in the post-WWII decades, and persuading twelve million readers of his most popular book to banish guilt and anxiety from sex in favor of pleasure and closer human understanding.

Comfort liked to say that everything he did was part of "one big project": to bring about a new consciousness, grounded in science, of the importance of personal responsibility in human relationships, including the obligation to disobey when authority was being exercised abusively. Polymath traces the intersection in Comfort's life and work between biology and literature, anarchism and humanism, sex and sociality, and how his writings, research, and activism continue to shed critical light on the moral and political choices we make today.

Laursen's book relates the event-filled life of a brilliant and complex figure, including his victory over a possibly career-ending disability, his tumultuous second marriage, his struggles with the scientific establishment, and the fascinating story of the making of The Joy of Sex.
