The philosophical personalities of the world represent an adventure in thinking. And when we examine the lives of the philosophers we find that the procession of a man's thoughts can be as exiting a spectacle as the pageantry of a man's deeds.

Few people have failed at love as spectacularly as the great philosophers. Although we admire their wisdom, history is littered with the romantic failures of the most sensible men and women of every age, including: Friedrich Nietzsche: "Ah, women. They make the highs higher and the lows more frequent." (Rejected by everyone he proposed to, even when he kept asking and asking.) Jean-Paul Sartre: "There are of course ugly women, but I prefer those who are pretty." (Adopted his mistress as his daughter.) Louis Althusser: "The trouble is there are bodies and, worse still, sexual organs." (Accidentally strangled his wife to death.) And dozens of other great thinkers whose words we revere—but whose romantic decisions we should avoid at all costs. Includes an excerpt from Andrew Shaffer's new book Literary Rogues.

Philosopher of the Heart is the groundbreaking biography of renowned existentialist Søren Kierkegaard’s life and creativity, and a searching exploration of how to be a human being in the world. Søren Kierkegaard is one of the most passionate and challenging of all modern philosophers, and is often regarded as the founder of existentialism. Over about a decade in the 1840s and 1850s, writings poured from his pen pursuing the question of existence—how to be a human being in the world?—while exploring the possibilities of Christianity and confronting the failures of its institutional manifestation around him. Much of his creativity sprang from his relationship with the young woman whom he promised to marry, then left to devote himself to writing, a relationship which remained decisive for the rest of his life. He deliberately lived in the swim of human life in Copenhagen, but alone, and died exhausted in 1855 at the age of 42, bequeathing his remarkable writings to his erstwhile fiancée. Clare Carlisle’s innovative and moving biography writes Kierkegaard’s life as far as possible from his own perspective, to convey what it was like actually being this Socrates of Christendom—as he put it, living life forwards yet only understanding it backwards.

Ancient biographies were more than accounts of the deeds of past heroes and guides for moral living. They were also arenas for debating pressing philosophical questions and establishing intellectual credentials, as Arthur P. Urbano argues in this study of biographies composed in Late Antiquity
