Sophocles 68
ancient Greek tragedian -496–-406 BCRelated quotes

“The immortal gods are wont to allow those persons whom they wish to punish for their guilt sometimes a greater prosperity and longer impunity, in order that they may suffer the more severely from a reverse of circumstances.”
Consuesse enim deos immortales, quo gravius homines ex commutatione rerum doleant, quos pro scelere eorum ulcisci velint, his secundiores interdum res et diuturniorem impunitatem concedere.
Book I, Ch. 14, translated by W. A. McDevitte and W. S. Bohn

Context: Heathenism is a state of mind. You can take it that I'm referring to one who does not see his world. He has no mental light. He destroys almost unwittingly. He cannot feel any Gods' presence in his life. He is the 21st century man. However, there's no theme or concept behind Heathen, just a number of songs but somehow there is a thread that runs through it that is quite as strong as any of my thematic type albums.

“A multitude of words is no proof of a prudent mind.”
As quoted in Diogenes Laërtius, The Lives and Opinions of Eminent Philosophers, I, 35; as translated in Dictionary of Quotations (Classical) edited by Thomas Benfield Harbottle, p. 455
Also translated as: "Many words do not declare an understanding heart."

A misquotation by Ronald Reagan in a 9 March 1982 speech, reported in Paul F. Boller, Jr., and John George, They Never Said It: A Book of Fake Quotes, Misquotes, & Misleading Attributions (1989), p. 13-14. In fact, Churchill used a very similar line ("To think you can make a man richer by putting on a tax is like a man thinking that he can stand in a bucket and lift himself up by the handle.") several times beginning with a speech at Free Trade Hall, Manchester, 19 February 1904.
