“What a strange thing that which men call pleasure seems to be, and how astonishing the relation it has with what is thought to be its opposite, namely pain! A man cannot have both at the same time. Yet if he pursues and catches the one, he is almost always bound to catch the other also, like two creatures with one head.”

“Fear is always in relation to something; it does not exist by itself. There is fear of what happened yesterday in relation to the possibility of its repetition tomorrow; there is always a fixed point from which relationship takes place. How does fear come into this? I had pain yesterday; there is the memory of it and I do not want it again tomorrow. Thinking about the pain of yesterday, thinking which involves the memory of yesterday’s pain, projects the fear of having pain again tomorrow. So it is thought that brings about fear. Thought breeds fear; thought also cultivates pleasure. To understand fear you must also understand pleasure – they are interrelated; without understanding one you cannot understand the other. This means that one cannot say ‘I must only have pleasure and no fear’; fear is the other side of the coin which is called pleasure.”

“When two members of a family or two intimate friends are separated, and one goes abroad and one remains at home, the return of the relative or friend who has been travelling always seems to place the relative or friend who has been staying at home at a painful disadvantage when the two first meet. The sudden encounter of the new thoughts and new habits eagerly gained in the one case, with the old thoughts and old habits passively preserved in the other, seems at first to part the sympathies of the most loving relatives and the fondest friends, and to set a sudden strangeness, unexpected by both and uncontrollable by both, between them on either side.”

“ 64. Surprising and Distressing Things While one is cleaning a decorative comb, something catches in the teeth and the comb breaks. A carriage overturns. One would have imagined that such a solid, bulky object would remain forever on its wheels. It all seems like a dream -- astonishing and senseless. A child or grown-up blurts out something that is bound to make people uncomfortable. All night long one has been waiting for a man who one thought was sure to arrive. At dawn, just when one has forgotten about him for a moment and dozed off, a crow caws loudly. One wakes up with a start and sees that it is daytime -- most astonishing. One of the bowmen in an archery contest stands trembling for a long time before shooting; when finally he does release his arrow, it goes in the wrong direction.”

“But confining myself more to the particular, I say that a prince may be seen happy to-day and ruined to-morrow without having shown any change of disposition or character. This, I believe, arises firstly from causes that have already been discussed at length, namely, that the prince who relies entirely upon fortune is lost when it changes. I believe also that he will be successful who directs his actions according to the spirit of the times, and that he whose actions do not accord with the times will not be successful. Because men are seen, in affairs that lead to the end which every man has before him, namely, glory and riches, to get there by various methods; one with caution, another with haste; one by force, another by skill; one by patience, another by its opposite; and each one succeeds in reaching the goal by a different method. One can also see of two cautious men the one attain his end, the other fail; and similarly, two men by different observances are equally successful, the one being cautious, the other impetuous; all this arises from nothing else than whether or not they conform in their methods to the spirit of the times. This follows from what I have said, that two men working differently bring about the same effect, and of two working similarly, one attains his object and the other does not.”

“But he finally saw how pain caused one of two things: A reverence for life. Or killing. Both grew from the same seed.”
