Demosthenes (384 BC - 322 BC)

He who confers a favor should at once forget it, if he is not to show a sordid ungenerous spirit. To remind a man of a kindness conferred and to talk of it, is little different from reproach.

Beware lest in your anxiety to avoid war you obtain a master.

Small opportunities are often the beginning of great enterprises.

Every advantage in the past is judged in the light of the final issue.

Nothing is easier than self-deceit. For what each man wishes, that he also believes to be true.

There is a great deal of wishful thinking in such cases; it is the easiest thing of all to deceive oneís self.

You cannot have a proud and chivalrous spirit if your conduct is mean and paltry; for whatever a man's actions are, such must be his spirit.

The easiest thing of all is to deceive one's self; for what a man wishes he generally believes to be true.

The fact speak for themselves.

All speech is vain and empty unless it be accompanied by action.

The man who has received a benefit ought always to remember it, but he who has granted it ought to forget the fact at once.
