"There is no opinion so stupid that..." - Quote by Marcus Tullius Cicero

“History is the teacher of life”

“It is not only arrogant, but it is profligate, for a man to disregard the world's opinion of himself.”

“Not only is there an art in knowing a thing, but also a certain art in teaching it.”

“What's the difference between beautiful and ugly?”

“Is the human race a joke? Was it devised and patched together in a dull time when there was nothing important to do?”

“There will be no end to the troubles of states, or of humanity itself, till philosophers become kings in this world, or till those we now call kings and rulers really and truly become philosophers, and political power and philosophy thus come into the same hands.”

“Every reform was once a private opinion.”

“It is the best book ever written on the subject. There is nothing like it!”

“Never do human beings speculate more, or have more opinions, than about things which they do not understand.”
