We do not belong to those who have ideas only among books, when stimulated by books. It is our habit to think outdoors–walking, leaping, climbing, dancing, preferably on lonely mountains or near the sea where even the trails become thoughtful. Our first questions about the value of a book, of a human being, or a musical composition are: Can they walk? Even more, can they dance?
–Friedrich Nietzsche, The Gay Science (366)
