Edward Gibbon: Most

“The most worthless of mankind are not afraid to condemn in others the same disorders which they allow in themselves; and can readily discover some nice difference in age, character, or station, to justify the partial distinction.”

Edward Gibbon The History of the Decline and Fall of the Roman Empire

Age

“Corruption, the most infallible symptom of constitutional liberty.”

Edward Gibbon

“… as long as mankind shall continue to bestow more liberal applause on their destroyers than their benefactors, the thirst of military glory will ever be the vice of the most exalted characters.”

Edward Gibbon

“In the spirit of enthusiasm or vanity, the prophet [Muhammad] rests the truth of his mission on the merit of his book; audaciously challenges both men and angels to imitate the beauties of a single page; and presumes to assert that God alone could dictate this incomparable performance. This argument is most powerfully addressed to a devout Arabian, whose mind is attuned to faith and rapture; whose ear is delighted by the music of sounds; and whose ignorance is incapable of comparing the productions of human genius… If the composition of the Koran exceed the faculties of a man to what superior intelligence should we ascribe the Iliad of Homer, or the Philippics of Demosthenes?”

“In the end, more than freedom, they wanted security. They wanted a comfortable life, and they lost it all – security, comfort, and freedom. When the Athenians finally wanted not to give to society but for society to give to them, when the freedom they wished for most was freedom from responsibility, then Athens ceased to be free and was never free again.”

Edward Gibbon

This quotation appeared in an article by Margaret Thatcher, "The Moral Foundations of Society" ( Imprimis, March 1995 https://imprimis.hillsdale.edu/the-moral-foundations-of-society/), which was an edited version of a lecture Thatcher had given at Hillsdale College in November 1994. Here is the actual passage from Thatcher's article:
<blockquote>[M]ore than they wanted freedom, the Athenians wanted security. Yet they lost everything—security, comfort, and freedom. This was because they wanted not to give to society, but for society to give to them. The freedom they were seeking was freedom from responsibility. It is no wonder, then, that they ceased to be free. In the modern world, we should recall the Athenians' dire fate whenever we confront demands for increased state paternalism.</blockquote>
The italicized passage above originated with Thatcher. In characterizing the Athenians in the article she cited Sir Edward Gibbon, but she seems to have been paraphrasing statements in "Athens' Failure," a chapter of classicist Edith Hamilton's book The Echo of Greece (1957), pp. 47–48 http://www.ergo-sum.net/books/Hamilton_EchoOfGreece_pp.47-48.jpg).

“It is difficult to paint the light, the various, the inconstant character of Gallienus, which he displayed without constraint, as soon as he became sole possessor of the empire. There were, however, a few short moments in the life of Gallienus, when, exasperated by some recent injury, he suddenly appeared the intrepid soldier and the cruel tyrant; till, satiated with blood, or fatigued by resistance, he insensibly sunk into the natural mildness and indolence of his character.In every art that he attempted, his lively genius enabled him to succeed; and as his genius was destitute of judgment, he attempted every art, except the important ones of war and government. He was a master of several curious, but useless sciences, a ready orator, an elegant poet, a skilful gardener, an excellent cook, and most contemptible prince...
