Education perverts the mind since we are directly opposing the natural development of our mind by obtaining ideas first and observations last. This is why so few men of learning have such sound common sense as is quite common among the illiterate.
Arthur SchopenhauerMan is the only animal who causes pain to others with no other object than wanting to do so.
Arthur SchopenhauerJust as a stream flows smoothly on as long as it encounters no obstruction, so the nature of man and animal is such that we never really notice or become conscious of what is agreeable to our will; if we are to notice something, our will has to have been thwarted, has to have experienced a shock of some kind.
Arthur Schopenhauer
