“ If he should be for compounding the matter, and adopting his own principle in part, and the principle of utility in part, let him say how far he will adopt it? When he has settled with himself where he will stop, then let him ask himself how he justifies to himself the adopting it so far? ”

“ By the natural constitution of the human frame, on most occasions of their lives men in general embrace this principle, without thinking of it: if not for the ordering of their own actions, yet for the trying of their own actions, as well as of those of other men. ”

“ It is in vain to talk of the interest of the community, without understanding what is the interest of the individual. ”

“ Is it possible for a man to move the earth? Yes; but he must first find out another earth to stand upon. ”

“ X. Of an action that is conformable to the principle of utility one may always say either that it is one that ought to be done, or at least that it is not one that ought not to be done. One may say also, that it is right it should be done ”

There are even few who have not taken some occasion or other to quarrel with it, either on account of their not understanding always how to apply it, or on account of some prejudice or other which they were afraid to examine into, or could not bear to part with. ”
