'Of Peace of Mind' Summary

Seneca begins by discussing the nature of peace of mind and its importance for human happiness. He argues that peace of mind is not simply the absence of trouble, but rather a state of inner calm and tranquility that is not easily disturbed by external events. Seneca then goes on to explore the various sources of inner turmoil and anxiety, such as the fear of death, the desire for wealth and power, and the opinions of others. He argues that these sources of anxiety can be overcome through the practice of Stoicism, which teaches us to focus on what is within our control and to accept what is not. Seneca concludes by offering a number of practical exercises and meditations that can help readers to achieve peace of mind and live a more fulfilling life.
