The History of every major Galactic Civilization tends to pass through
three distinct and recognizable phases, those of Survival, Inquiry, and
Sophistication, otherwise known as the How, Why, and Where phases. For
instance, the first phase is characterized by the question "How can we eat?"
the second by "Why do we eat?" and the third by "Where shall we have lunch?".
