A true aristocrat, Castiglione insisted, should preserve one's composure in all circumstances, and behave with unaffected nonchalance and effortless dignity. Such nonchalance he called sprezzatura:
It is an art which does not seem to be an art. One must avoid affectation and practice in all things a certain sprezzatura, disdain or carelessness, so as to conceal art, and make whatever is done or said appear to be without effort and almost without any thought about it.
