“The square dance fiddlers first concern is to carry a tune, but he must carry it loud enough to be heard over the noise of stamping feet, the cries of the caller, and the shouts of the dancers. When he fiddles, he fiddles all over; feet, hands, knees, head, and eyes are all busy.”

“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of naturefor instance in a biological survey of evolutionwe are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
