The author is the great ancient Greek philosopher Plato, a student of Socrates. In this book, Socrates defends his ideals and proves his innocence during a trial where he has to answer for his philosophy and actions. The book "Apology of Socrates" not only makes the reader think about justice and truth, but also helps to better understand the life principles of the great thinker. This work is not only a testimony about the life of Socrates, but also an invitation to deep philosophical reflection.
