When it comes to good quotes, Samuel Langhorne Clemens (1835-1910), better known as Mark Twain, belongs in a category all by himself.
"A lie can travel half way around the world while the truth is putting on its shoes."
"If you pick up a starving dog and make him prosperous, he will not bite you. This is the principal difference between a dog and a man."
"If you tell the truth you don't have to remember anything."
"Let us endeavor so to live that when we come to die even the undertaker will be sorry."
"Most writers regard the truth as their most valuable possession, and therefore are economical in its use."

"The jury system puts a ban upon intelligence and honesty and a premium upon ignorance, stupidity and perjury." (from Roughing It)
"A banker is a fellow who lends you his umbrella when the sun is shining and wants it back the minute it begins to rain."
"Reader, suppose you were an idiot. And suppose you were a member of Congress. But I repeat myself."
"In the real world, the right thing never happens in the right place and the right time. It is the job of journalists and historians to make it appear that it has."
"History may not repeat itself, but it does rhyme a lot."

"Clothes make the man. Naked people have little or no influence on society."

"It is chloroform in print." (Mark Twain describing a really boring book)
"The Jews constitute but one percent of the human race . . . Properly the Jew ought hardly to be heard of. He is as prominent on the planet as any other people . . . He has made a marvelous flight in this world, in all the ages; and he has done it with his hands tied behind him . . . The Egyptian, the Babylonian, and the Persian rose, filled the planet with sound and splendor, then faded to dreamstuff and passed away; the Greek and the Roman followed, and made a vast noise, and they are gone; other peoples have sprung up and held their torch high for a time, but it burned out, and they sit in twilight now, or have vanished. The Jew saw them all, beat them all, and is now what he always was . . . All things are mortal but the Jew; all other forces pass, but he remains. What is the secret of his immortality?" (from The Complete Essays of Mark Twain, Charles Neider, editor, New York, Doubleday, 1963, pg. 249, quoted by Benjamin Netanyahu in A Place Among the Nations, New York, Bantam, 1993, pg. 400)
