Arthur SchopenhauerTwo Chinamen visiting Europe went to the theatre for the first time. One of them occupied himself with trying to understand the theatrical machinery, which he succeeded in doing. The other, despite his ignorance of the language, sought to unravel the meaning of the play. The former is like the astronomer, the latter the philosopher.
Arthur SchopenhauerAll the cruelty and torment of which the world is full is in fact merely the necessary result of the totality of the forms under which the will to live is objectified.
Arthur SchopenhauerThere is not much to be got anywhere in the world. It is filled with misery and pain; if a man escapes these, boredeom lies in wait for him at every corner. Nay more; it is evil which generally has the upper hand, and folly that makes the most noise. Fate is cruel and mankind pitiable.
Arthur Schopenhauer
