The function of science fiction is not always to predict the future but sometimes to prevent it.
Frank HerbertBeware of the truth, gentle Sister. Although much sought after, truth can be dangerous to the seeker. Myths and reassuring lies are much easier to find and believe. If you find a truth, even a temporary one, it can demand that you make painful changes. Conceal your truths within words. Natural ambiguity will protect you then.
Frank Herbert
