Truth is not that which can be demonstrated by the aid of logic. If orange-trees are hardy and rich in fruit in this bit of soil and not that, then this bit of soil is what is truth for orange-trees. If a particular religion, or culture, or scale of values, if one form of activity rather than another, brings self-fulfillment to a man, releases the prince asleep within him unknown to himself, then that scale of values, that culture, that form of activity, constitute his truth. Logic, you say? Let logic wangle in its own explanation of life.
Antoine de Saint-Exupéry
Wind, Sand and Stars (1939)
