Demosthenes Quotes
It is not possible to found a lasting power upon injustice, perjury, and treachery. These may, perhaps, succeed for once, and borrow for awhile, from hope, a gay and flourishing appearance. But time betrays their weakness, and they fall into ruin of themselves. For, as in structures of every kind, the lower parts should have the greatest firmness--so the grounds and principles of actions should be just and true.
Demosthenes. The Olynthiac and Other Public Orations of Demosthenes. Translated by Charles Rann Kennedy, Henry G. Bohn, 1852, p. 40.
Demosthenes was a Greek statesman and orator of ancient Athens. His orations constitute a significant expression of contemporary Athenian intellectual prowess and provide an insight into the politics and culture of ancient Greece during the 4th century BC. Demosthenes learned rhetoric by studying the speeches of previous great orators. He delivered his first judicial speeches at the age of 20, in which he argued effectively to gain from his guardians what was left of his inheritance. For a time, Demosthenes made his living as a professional speech-writer (logographer) and a lawyer, writing speeches for use in private legal suits.
