Cicero: “Again, there are certain duties that we owe even to those who have wronged us.”

He was wrong; for deceit does not remove the guilt of perjury--it merely aggravates it. #The ancient Roman discipline.# His cunning that impudently tried to masquerade as prudence was, therefore, only folly.

In the matter of a promise one must always consider the meaning and not the mere words.

And it is a great man's duty in troublous times to single out the guilty for punishment, to spare the many, and in every turn of fortune to hold to a true and honourable course.

Moreover, all our thought and mental activity will be devoted either to planning for things that are morally right and that conduce to a good and happy life, or to the pursuits of science and learning.
