Sooner or later in life everyone discovers that perfect happiness is unrealizable, but there are few who pause to consider the antithesis: that perfect unhappiness is equally unattainable. The obstacles preventing the realization of both these extreme states are of the same nature: they derive from our human condition which is opposed to everything infinite.

Sooner or later in life, everyone discovers that perfect happiness is unrealizable, but there are few who pause to consider the antithesis: that perfect unhappiness is equally unobtainable . . . Our ever-sufficient knowledge of the future opposes it and this is called in the one instance: hope.

Sooner or later in life everyone discovers that perfect happiness is unrealizable, but there are few who pause to consider the antithesis: that perfect unhappiness is equally unattainable. The obstacles preventing the realization of both these extreme states are of the same nature: they derive from our human condition, which is opposed to everything infinite. Our ever-insufficient knowledge of the future opposes it: and this is called, in the one instance, hope, and in the other, uncertainty of the following day. The certainty of death opposes it: for it places a limit on every joy, but also on every grief. The inevitable material cares oppose it: for as they poison every lasting happiness, they equally assiduously distract us from our misfortunes and make our consciousness of them intermittent and hence supportable.

Caselli was a modest, taciturn man, in whose sad but proud eyes could be read:
- He is a great scientist, and as his 'famulus', I am also a little great;
- I, though humble, know things that he does not know;
- I know him better than he knows himself; I foresee his acts;
- I have power over him; I defend and protect him;
- I can say bad things about him because I love him; that is not granted to you

"Аз обаче си извлякох друга поука, по-простичка и по-конкретна, и смятам, че всеки радетел на нашата наука би могъл да я потвърди: не бива да имаме вяра на почти същото (натрият е почти същият като калия, но с натрия нищо подобно нямаше да се случи), на практически еднаквото, на приблизителното, на разните "горе-долу" и "или евентуално", на заместителите и кръпките. Макар и нищожни, несходствата могат да доведат до драматично различни резултати - както железопътните стрелки - и голяма част от професията на химика се състои тъкмо в предпазването от такива несходства, в познаването им отблизо, в предвиждането на техните последици. Впрочем нещо, което важи не само за химиците."

Сандро не обичаше часовниците: възприемаше неспирния им низ от мълчаливи предупреждения като нагло вмешателство.
