"Always Drink Upstream..." was written as a wake-up call, because once you've found water in a desert full of thirsty people, you have to shout: There's water here! The driving philosophical principle behind "Always Drink Upstream..." is that the entire history of human culture is the antagonism between two points of view - a static world view and a dynamic world view, where everything is constantly evolving. History teaches us that the static world view is exceedingly dangerous, and from it have sprung the fanatics of every age. They say "we possess the absolute truth, and all other beliefs are "false." When this mindset holds power in politics, wars and terrorism occur. When they hold sway in religion, persecution.
