Jacob Burckhardt, The Civilisation of the Renaissance in Italy
“ All are at one on the point, that, in the case of those injuries and insults for which Italian justice offered no redress, and all the more in the case of those against which no human law can ever adequately provide, each man is free to take the law into his own hands. Only there must be art in the vengeance, and the satisfaction must be compounded of the material injury and moral humiliation of the offender. A mere brutal, clumsy triumph of force was held by public opinion to be no satisfaction. The whole man with his sense of fame and of scorn, not only his fist, must be victorious. ”
