The man who sees two or three generations is like one who sits in the conjuror's booth at a fair, and sees the same tricks two or three times. They are meant to be seen only once.
Arthur SchopenhauerA man's knowledge may be said to be mature, in other words, when it has reached the most complete state of perfection to which he, as an individual, is capable of bringing it, when an exact correspondence is established between the whole of his abstract ideas and the things he has actually perceived for himself. His will mean that each of his abstract ideas rests, directly or indirectly, upon a basis of observation, which alone endows it with any real value; and also that he is able to place every observation he makes under the right abstract idea which belongs to it.
Arthur SchopenhauerWhether we are in a pleasant or a painful state depends, finally, upon the kind of matter that pervades and engrosses our consciousness and what we compare it to - better and we envious and sad, worse and we feel grateful and happy.
Arthur SchopenhauerThe vanity of existence is revealed in the whole form existence assumes: in the infiniteness of time and space contrasted with the finiteness of the individual in both; in the fleeting present as the sole form in which actuality exists; in the contingency and relativity of all things; in continual becoming without being; in continual desire without satisfaction; in the continual frustration of striving of which life consists. . . Time is that by virtue of which everything becomes nothingness in our hands and loses all real value.
