Letters from a Stoic by Seneca

Letters from a Stoic by Seneca is a collection of moral letters written to Lucilius about how to live wisely. Seneca discusses time, death, friendship, wealth, fear, anger, virtue, study, and the discipline of the mind. The letters present philosophy as a practical way of shaping daily conduct rather than an abstract exercise. Seneca repeatedly argues that external possessions and honors are less important than inner freedom and moral strength. His tone is personal, direct, and often urgent, as if advising both his friend and himself. The work remains one of the most accessible introductions to Stoic thought.
