How commendable in a prince it is to keep his word and live with integrity, not making use of cunning and subtlety, everyone knows well. Yet we see by experience in these our days that those princes have effected great matters who have made small reckoning of keeping their words and have known by their craft to turn and wind men about and in the end have overcome those who have grounded upon the truth.
