"Two causes prevented these seeds from developing at that time, as they did afterwards. In the first place, it was a matter that concerned myself: and private interest, which has never produced anything great or noble, cannot draw from my heart the divine flights which only the purest love of the just and the beautiful can produce; in the second place, the charm of friendship moderated and calmed my anger by the ascendency of a gentler feeling."
