A slight change of idea can be the difference between prevailing peace or rolling horrors upon the Earth.

Every great ideology, philosophy, pattern of government, and conception of reality began as a mere idea in the mind of a man. They are but small things, and a man can turn his mind from one idea to another with little consequence. He has but simple thought experiments, ideas of how things could be. And in the simulations of his mind, his ideas may all seem correct, innocent, and only geared to the good of mankind.

But as the idea grows, and leaves the mind, and takes hold of the masses, then it becomes argument, then creed, then party, then nation. And as it grows, so do the consequences, and so some ideas become the foundation for flourishing and joy, and some become the foundation for purge and war.
