“Wealth is like sea-water; the more we drink, the thirstier we become; and the same is true of fame.”

“Science is not a taxi-cab that we can get in and out of whenever we like.”

“We will gradually become indifferent to what goes on in the minds of other people when we acquire a knowledge of the superficial nature of their thoughts, the narrowness of their views and of the number of their errors. Whoever attaches a lot of value to the opinions of others pays them too much honor.”

“When we see that almost everything men devote their lives to attain, sparing no effort and encountering a thousand toils and dangers in the process, has, in the end, no further object than to raise themselves in the estimation of others; when we see that not only offices, titles, decorations, but also wealth, nay, even knowledge[1] and art, are striven for only to obtain, as the ultimate goal of all effort, greater respect from one's fellowmen,—is not this a lamentable proof of the extent to which human folly can go?”

“We forfeit three-fourths of ourselves in order to be like other people.”

“However, the struggle with that sentinel is, as a rule, not so hard as it may seem from a long way off, mainly in consequence of the antagonism between the ills of the body and the ills of the mind. If we are in great bodily pain, or the pain lasts a long time, we become indifferent to other troubles; all we think about is to get well. In the same way great mental suffering makes us insensible to bodily pain; we despise it; nay, if it should outweigh the other, it distracts our thoughts, and we welcome it as a pause in mental suffering. It is this feeling that makes suicide easy; for the bodily pain that accompanies it loses all significance in the eyes of one who is tortured by an excess of mental suffering. This is especially evident in the case of those who are driven to suicide by some purely morbid and exaggerated ill-humor. No special effort to overcome their feelings is necessary, nor do such people require to be worked up in order to take the step; but as soon as the keeper into whose charge they are given leaves them for a couple of minutes, they quickly bring their life to an end.When, in some dreadful and ghastly dream, we reach the moment of greatest horror, it awakes us; thereby banishing all the hideous shapes that were born of the night. And life is a dream: when the moment of greatest horror compels us to break it off, the same thing happens.”

“Sleep is the interest we have to pay on the capital which is called in at death; and the higher the rate of interest and the more regularly it is paid, the further the date of redemption is postponed. ”
