"When an ingenious track of thinking presents itself, though but casually, to true genius, occupied it may be with something else, imagination darts alongst it with great rapidity; and by this rapidity its ardor is more inflamed. The velocity of its motion sets it on fire, like a chariot wheel which is kindled by the quickness of its revolution."
— Gerard, Alexander (1728-1795)
