Stoicism, the most influential school of thought in the Roman Empire, offers powerful ways to strengthen character in the face of modern challenges. Considered the most talented and humane writer in the history of Stoicism, Seneca teaches us the need for freedom and purpose in life. His most voluminous work, more than a hundred Moral Letters to Lucilius addressed to a close friend, tells how to learn the lost art of friendship and realize its true nature, how to overcome anger, how to face grief, how to turn failures into opportunities for development, how living in society, how to be sincere, how to live without fear of death, how to deeply experience love and gratitude, and how to find freedom, peace and joy. In this book, the translation rights of which were bought by 14 countries, philosopher David Fideler analyzes the classic works of Seneca , explaining his ideas without simplifying them. Seneca's wisdom is best enjoyed through a daily ritual like a stimulating cup of coffee, digesting time-tested truths about the human soul that, as it turns out, has not changed much in the past two thousand years. “My ideal of a modern Stoic sage is a man who transforms fear into prudence, pain into information, mistakes into initiative, desire into action. Seneca created a complete course of study on how to manage your life and use emotions for their intended purpose - thanks to small but effective tricks." (N. N. Taleb)
