Aristotle was the first philosopher to write ethical treatises. His best-known work in this field, The Nicomachean Ethics, consists of 10 books addressing the question of how the individual should best live. For Aristotle, ethics seeks to determine what makes a virtuous character possible, which is essential for a state of well-being. He describes a sequence of necessary steps to achieve this, such as righteous actions that promote the development of the right habits. He examines the moral virtues and their corresponding vices, like courage versus fear.

This is a summary of Marcus Aurelius’ Meditations. Meditations is essentially a scrapbook of thoughts written over a 19-year period; it’s not ordered and it repeats itself frequently as ideas reoccurred to the author at different times. For this reason, it can be hard for a casual reader to extract the myriad messages contained within. This summary helps in that by interpreting Meditations and reducing it from around 50,000 words down to 4,400. While it has been interpreted, the author has done his best not to embellish it.
