George Edward Moore,
Principia Ethica — Chapter VI
(1903)
“ To deny and exclude matter, is to deny and exclude the best we know. That a thing may retain its value, while losing some of its qualities, is utterly untrue. All that is true is that the changed thing may have more value than, or as much value as, that of which the qualities have been lost. What I contend is that nothing, which we know to be good, and which contains no material qualities, has such great value that we can declare it, by itself, to be superior to the whole which would be formed by the addition to it of an appreciation of material qualities. ”
