The only absolute truth is change, and death is the only way to stop change. Life is a series of judgments on changing situations, and no ideal, no belief fits every solution. Yet humans need to believe in something beyond themselves. Perhaps all intelligences do. If we do not act on higher motivations, then we can justify any action, no matter how horrible, as necessary for our survival. We are endlessly caught between the need for high moral absolutes—which will fail enough that any absolute can be demonstrated as false—and our tendency for individual judgments to degenerate into self-gratifying and unethical narcissism. Trying to force absolutes on others results in death and destruction, yet failing to act beyond one's self also leads to death and destruction, generally a lot sooner.
