"And since nothing appears to me to give children so much becoming confidence and behaviour, and so to raise them to the conversation of those above their age, as dancing, I think they should be taught to dance as soon as they are capable of learning it. For tho' this consist only in outward gracefulness of motion, yet, I know not how, it gives children manly thoughts and carriage, more than any thing."
--John Locke, Some Thoughts Concerning Education, 1692.
