“There is no man that imparteth his joys to his friend, but he joyeth the more; and no man that imparteth his griefs to his friend, but he grieveth the less.”

Source identified6
In taking revenge, a man is but even with his enemy; but in passing it over, he is superior.

“In taking revenge, a man is but even with his enemy; but in passing it over, he is superior.”

Bacon argues that retaliation merely mirrors the wrong, whereas refusing revenge can restore agency by ending the cycle instead of remaining governed by the injury.

Source details

Francis Bacon, essay IV ‘Of Revenge,’ represented by Project Gutenberg #575. The frozen catalog sentence capitalizes the extracted opening ‘In’ and ends after ‘superior’; the witness reads it inside the longer sentence beginning ‘Certainly, in taking revenge...’ and continuing ‘for it is a prince's part to pardon.’ It remains early-modern moral and legal-political essay argument rather than modern clinical anger guidance.

Source identified7

Source details

Source identified11

“If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties.”

Intellectual confidence can be improved by beginning with questions rather than pretending certainty too early.

Source details

The Advancement of Learning, First Book, Project Gutenberg #5500, transcribed from the 1893 Cassell & Company edition. Bacon contrasts impatience of doubt with mature suspension of judgment and then sets out two ways of contemplation before saying that beginning with certainties ends in doubts while beginning with doubts can end in certainties. It remains early-modern epistemological argument rather than a modern experimental rule for scientific method.
