Daniel really knew of no way to regulate his actions other than to be rational. Princes were taught a thing or two about being rational, as they were taught to play a little lute and dance a passable ricercar. But what drove their actions was their own force of will; in the end they did as they pleased, rational or not. Daniel had liked to tell himself that rational thought led to better actions than brute force of will; yet here was the Duke of York all but rolling his eyes at them and their experiment, seeing naught that was new.
