After some delay, postponement, and hesitation (not to mention illness) I think I am now fully committed to writing the book on Marcus Aurelius that I agreed to do some time ago. It was supposed to be the first volume in a new series of books on Roman Philosophy for Acumen, just as my Stoicism book was the first in their series Ancient Philosophies. Since then, Acumen have been bought out by Routledge and, due to my delays, Raphael Woolf's Cicero has jumped ahead to become the first volume in what is now the Routledge series Philosophy in the Roman World. Other volumes planned for the series will be on Seneca, Lucretius, Galen, and Plutarch.
Since first agreeing to do it I have been invited to write a number of shorter pieces on Marcus. These include chapters in the Wiley-Blackwell Companion to Marcus Aurelius and The Oxford Handbook of Roman Philosophy, as well as a bibliography on him for Oxford Bibliographies Online. More recently I have been asked to write about him for Brill's Companion to the Reception of Socrates. All these works will feed into the book.
