“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.”

“As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power.”

“For the will, as that which is common to all, is for that reason also common: consequently, every vehement emergence of will is common, i.e. it demeans us to a mere exemplar of the species.He, who on the other hand. who wants to be altogether uncommon, that is to say great, must never let a preponderant agitation of will take his consciousness altogether, however much he is urged to do so.He must, e.g., be able to take note of the odious opinion of another without feeling his own aroused by it: indeed, there is no surer sign of greatness than ignoring hurtful or insulting expressions by attributing them without further ado, like countless other errors, to the speaker's lack of knowledge and thus merely taking note of them without feeling them.”

“When we read, another person thinks for us: we merely repeat his mental process. In learning to write, the pupil goes over with his pen what the teacher has outlined in pencil: so in reading; the greater part of the work of thought is already done for us. This is why it relieves us to take up a book after being occupied with our own thoughts. And in reading, the mind is, in fact, only the playground of another’s thoughts. So it comes about that if anyone spends almost the whole day in reading, and by way of relaxation devotes the intervals to some thoughtless pastime, he gradually loses the capacity for thinking; just as the man who always rides, at last forgets how to walk. This is the case with many learned persons: they have read themselves stupid.”

“A book can never be anything more than the impress of its author's thoughts; and the value of these will lie either in the matter about which he has thought, or in the form which his thoughts take, in other words, what it is that he has thought about it.”

“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.”

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