While William Irvine’s book introduced me to Stoic philosophy, Donald took me further into the incredible life of Roman emperor and Stoic Marcus Aurelius. This book takes you deeper into Stoic philosophy. I get asked whom I’d want to have lunch with, dead or alive, and I answer Marcus Aurelius. During his reign he was the most powerful person in the Western hemisphere. History is littered with examples that prove Lord Acton’s quip “Power corrupts; absolutely power corrupts absolutely.” Marcus is a rare exception.

When I began writing about Emerson – not a usual task for a philosopher -- and was trying to figure out who the American Transcendentalists were, Barbara Packer’s brilliantly written study of the movement came to my assistance. She covers it all, from the background in European Biblical criticism and the idea that the sacred books of the world’s religious traditions are forms of poetry, to the Annus Mirabilus of 1836 when Emerson published Nature; to figures like Margaret Fuller, whose electrifying Conversations sparked a homegrown American feminism, Bronson Alcott (father of Louisa May), and, of course, Emerson’s young friend, Henry David Thoreau, author of Walden and Resistance to Civil Government.

In my college days, it seemed that everyone was carrying around a copy of Barzun’s book on Darwin, Marx, and Wagner, and I remember devouring his two-volume book on Berlioz and the Romantic Century, just for fun. When I began to seriously study William James, I was amazed to see that Barzun had written about him too. A Stroll with William James has one of my favorite titles, signifying a certain American informality and inherent movement that is characteristic of both James the man and his philosophy of pragmatism.

Barzun’s engagingly written book contains chapters on James’s life, his relation to his brother Henry James the novelist, and on William’s masterwork, The Principles of Psychology, with its great chapter on “the stream of thought.” Barzun also considers the brilliant “study in human nature” that James calls The Varieties of Religious Experience, with its chapters on conversion, mysticism, and… show more.

The figure of Ludwig Wittgenstein has always been quite enigmatic for me.

The enormous contradictions of his life and the intensity of it are difficult to understand in the abstract. Ray Monk's biography contextualizes the life and work of the Austrian philosopher who set out to solve all the problems of philosophy.

Monk's biography stands as a testament to Wittgenstein's enduring influence on our understanding of language, thought, and reality. 

Any marriage can fall apart. We can become lost to each other. But we can also re-find each other.

In many ways, a marriage is constantly a remarriage. The philosopher Stanley Cavell, my Ph.D. advisor at Harvard, wrote a brilliant book about what he calls the remarriage comedies of the late 30s and early 40s.

The films are great on their own—The Philadelphia Story, The Awful Truth, etc—, but their power and wisdom becomes part of a profound philosophical conversation through Cavell’s inquiry and voice. My own book explores love and marriage in resonant, but different ways. 

Although some people assume we don’t know much about Marcus Aurelius, the truth is that we probably know more about him than most other ancient philosophers, and certainly, there are several modern biographies of Marcus Aurelius but the best is this one by the British historian, Anthony Birley. Birley adopts a scholarly approach but he also keeps quite a tight focus on the events of Marcus’ life. (Frank McLynn’s biography is more widely-read but ranges more freely over topics such as the Roman empire’s economy.)  

John Sellars is a British academic philosopher and one of the leading modern scholars of Stoicism but he’s also a great communicator and his writings are easily accessible to nonacademics. Many readers assume, at first glance, that the Meditations consist of “random musings.” However, this recent work on the philosophy underlying Marcus Aurelius’ thought helps to expose the systematic nature of his reasoning. 

This is the most recent translation of Marcus Aurelius’ Meditations, at the time of writing but I’m mainly including it because of Robin Waterfield’s very thorough annotations, which are invaluable when it comes to understanding some of the more obscure passages. They provide historical and philosophical context that’s otherwise missing and make it much easier to appreciate what Marcus was trying to say.

This is a large and expensive academic book containing over thirty chapters by different authors (disclaimer: two of them are by me).

It’s perhaps not the sort of thing that a typical general reader is likely to buy. But taken together, these chapters constitute the fullest discussion of Marcus Aurelius available in English, and most questions that people are likely to have about Marcus or his philosophy are probably answered somewhere in its five hundred-plus pages.

This book contains a selection of letters from the correspondence between Marcus Aurelius and his rhetoric teacher Fronto. Most of these letters date from Marcus’s youth and show a quite different side to his character.

Richlin argues – controversially – that some of these letters give evidence of a homosexual relationship between Marcus and Fronto. Although I’m not convinced by that claim, this volume remains a really helpful way to access these letters in a modern translation with helpful notes. The youthful Marcus we meet is a nice counterpoint to the older Marcus of the Meditations.
