"Pleasantry is never good on serious points,..." - Quote by Voltaire

“Whoever serves his country well has no need of ancestors.”

“In France every man is either an anvil or a hammer; he is a beater or must be beaten.”

“No problem can withstand the assault of sustained thinking.”

“I would rather have my ignorance than another man's knowledge, because I have so much of it.”

“2-in-1 is a stupid term, because 1 is not big enough to hold 2. That's why 2 was created.”

“The longer I live, the more convinced am I that this planet is used by other planets as a lunatic asylum.”

“It is my belief, you cannot deal with the most serious things in the world unless you understand the most amusing.”

“A man who takes himself too seriously will find that no one else takes him seriously.”

“I speak and the child plays: who can be more serious than we are?”
