Nothing mortal is enduring, and there is nothing sweet which does not presently end in bitterness.
PetrarchWhere you are is of no moment, but only what you are doing there. It is not the place that ennobles you, but you the place, and this only by doing that which is great and noble.
PetrarchMan has no greater enemy than himself. I have acted contrary to my sentiments and inclination; throughout our whole lives we do what we never intended, and what we proposed to do, we leave undone.
PetrarchEach famous author of antiquity whom I recover places a new offence and another cause of dishonor to the charge of earlier generations, who, not satisfied with their own disgraceful barrenness, permitted the fruit of other minds, and the writings that their ancestors had produced by toil and application, to perish through insufferable neglect. Although they had nothing of their own to hand down to those who were to come after, they robbed posterity of its ancestral heritage.
