Discover the philosophical theories of ancient Greece that shaped global philosophical thought and deeply influenced culture, science, and ethics. In this book, Socrates speaks about the value of self-knowledge and the pursuit of truth, his student and founder of the Academy, Plato, discusses the illusion of the material world and the consciousness of the soul in the world of Ideas, and Pythagoras of Samos, the proponent of the harmony of the Universe, talks about reprogramming the mind for the best life. Philosophy is a wonderful journey worth embarking on. The ancient Greek philosophers said it all thousands of years before our time. From Socrates' "I know one thing, that I know nothing" to the Delphic exhortation "know thyself." A deeper connection with ourselves brings harmony to all aspects of our lives. Because in this way, we live consciously and invest in what truly evolves our soul. The exercises and practices in the book are daily "contemplation" tools that combine ancient Greek philosophy with self-improvement and personal development techniques.
