The main idea of Soteriological Philosophy can be summarized in a simple formulation: man, as we encounter him in life, is an imperfect being. Something radical and essential can be changed in him during his adult life, provided that he himself pursues his Growth in an active and
persistent manner. This notion presented by Plato in his well-known “parable of the cave” is found in one way or another in all great religious traditions. Referred to as "entering the Kingdom of Heaven", or "Enlightenment", "Awakening" or even "Nirvana" in the history of ideas, the “Salvation of Man”
refers to a possibility of Mind to evolve- a possibility described and explored by a great number of philosophers. From Parmenides, Pythagoras and Anaxagoras, Socrates, Plato, Proclus, Plotinus, Damascius, Simplicius, Antoninus, Olympiodorus and others to Plethon Gemistos and the modern Georgios Georgiades (Gurdjieff), a long chain of philosophers, whose power has been reborn again and again through time, focused their teaching on Human Development, dealt practically with it, and within the framework of their Philosophical Schools gave their students all kinds of spiritual exercises and meditative practices. But unlike the "supernatural" explanations given on the evolution of Man by various religious teachings, the work of these Philosophers developed within the framework of the scientific thought of their time in a strictly rational manner.
