No one can be perfectly free till all are free; no one can be perfectly moral till all are moral; no one can be perfectly happy till all are happy. - Herbert Spencer

No one can be perfectly happy till all are happy.

Each new ontological theory, propounded in lieu of previous ones shown to be untenable, has been followed by a new criticism leading to a new scepticism. All possible conceptions have been one by one tried and found wanting; and so the entire field of speculation has been gradually exhausted without positive result: the only result reached being the negative one above stated, that the reality existing behind all appearances is, and must ever be, unknown.

Ethical ideas and sentiments have to be considered as parts of the phenomena of life at large. We have to deal with man as a product of evolution, with society as a product of evolution, and with moral phenomena as products of evolution.

People ... become so preoccupied with the means by which an end is achieved, as eventually to mistake it for the end. Just as money, which is a means of satisfying wants, comes to be regarded by a miser as the sole thing to be worked for, leaving the wants unsatisfied; so the conduct men have found preferable because most conducive to happiness, has come to be thought of as intrinsically preferable: not only to be made a proximate end (which it should be), but to be made an ultimate end, to the exclusion of the true ultimate end.
