Really liked this Ted Sturgeon quote
from his essay "Science Fiction, Morals, and Religion":
...recognition of what I have come to call the "infrarational" - that source of belief, faith, and motive which exists beside and above reason. So conditioned have we been by Aristotle, Kant, and Freud that we tend to believe that any force, object or problem will yield to rational processes; when they don't, we blame the process and call up yet more logic. The infrarational, however, is a very large component in us, and while reason calls it ignorance or stupidity (viz, trying to talk someone out of a fear of the dark or of snakes), it is neither. It is the infrarational, source of many of our motivations and the tint reservoir of much of our thinking. We will never succeed in reaching our optimum as a species until we learn the nature of the infrarational. We may fail as a species unless we do. The urge to worship - as ubiquitous and commanding as sex - has its origins there.
