The Meditations are a set of personal reflections by Marcus Aurelius. He writes about the vicissitudes of his own life and explores how to live wisely and virtuously in an unpredictable world. He was a follower of the Stoic tradition of philosophy, and one of its finest advocates, both in the clarity of his writing and in the uprightness of his life. The aphorisms show how for him, as perhaps for us all, the answer to life lies in keeping a calm and rational mind, and in refusing to be cast down or alarmed by things over which we have no control.
