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.

I have long held the opinion that the amount of noise that anyone can bear undisturbed stands in inverse proportion to his mental capacity and therefore be regarded as a pretty fair measure of it.

Optimism is not only a false but also a pernicious doctrine, for it presents life as a desirable state and man's happiness as its aim and object.

If, as usually happens, these do not fall to his lot, he believes that he suffers an injustice, in fact that he misses the whole point of his existence.

As soon as a rung has raised him up one step, he leaves it behind. On the other hand, the many who study in order to fill their memory do not use the rungs of the ladder for climbing, but take them off and load themselves with them to take away, rejoicing at the increasing weight of the burden. They remain below forever, because they bear what should have bourne them.
