These were preparatory words a great Greek master wrote for his disciple Pausanias. His name was Empedocles (490–430 BC) and he belonged to the Pythagorean tradition. His teaching, always expressed in poetry, embraced psychology, cosmology, biology, astronomy, medicine and chemistry, contributing to the inception of the modern science, and consequently, the modern world. But unlike contemporary thinkers and scientists, he understood humans are asleep, that a special attitude and perception are required to live lucidly...What Empedocles had to say about that will be the theme of the next post.
