George Edward Moore,
Principia Ethica — Chapter V
(1903)
“ Can we lay down any general rules to the effect that one among a few alternative actions will generally produce a greater total of good in the immediate future? It is important to insist that this question, limited as it is, is the utmost, to which, with any knowledge we have at present or are likely to have for a long time to come, Practical Ethics can hope to give an answer. I have already pointed out that we cannot hope to discover which is the best possible alternative in any given circumstances, but only which, among a few, is better than the others. ”
