On occasion I have seen the following quote attributed to Plato, but I think it is an error that may have begun with a mis-attribution in Elbert Hubbard’s Scrapbook and which has been passed down through the generations :

“A bad man is wretched amidst every earthly advantage: a good man—troubled on every side, yet not distressed; perplexed, but not in despair; persecuted, but not forsaken; cast down, but not destroyed.”

I have read through the whole corpus of Plato’s dialogues without coming across anything similar. Further, an internet search turns up nothing of substance.

The quote is almost identical to what we find in Paul’s epistle to the Corinthians;

We are hard-pressed on every side, yet not crushed; we are perplexed, but not in despair; persecuted, but not forsaken; struck down, but not destroyed— (2 Corinthians 4:8-9)

I suspect that Hubbard picked up the quote from one of the early Christian neo-platonists who was paraphrasing Paul’s message and that in the process Hubbard botched the source. However, I would be very appreciative if anyone can provide information.

Plato's ManDiogenes Laertius has handed down to us some fascinating source material in his work Lives of Eminent Philosophers. The historical background he provides for Paul’s address on Mars Hill is extremely enlightening, and yet it seems to be completely ignored by most expositors of the book of Acts. Read more

One who throws a stone has power over it until he has thrown it, but not afterwards.

Every action must be due to one or other of seven causes: chance, nature, compulsion, habit, reasoning, anger, or appetite.

Reason is a light that God has kindled in the soul.

Anybody can become angry — that is easy; but to be angry with the right person, and to the right degree, and at the right time, and for the right purpose, and in the right way — that is not within everybody’s power and is not easy.
