G. E. Moore

“ If the reader wishes to form an impartial judgment as to what the fundamental problems of Ethics really are, and what is the true answer to them, it is of the first importance that he should not confine himself to reading works of any one single type, but should realise what extremely different sorts of things have seemed to different writers, of acknowledged reputation, to be the most important things to be said about the subject. ”

“ No doubt, in some cases, other works, equally well worth reading, and equally typical of the sort of differences I want to emphasise, might be substituted for some of those I have mentioned; but these are, I think, as good as any for the purposes of illustration, and hardly one of them could be omitted without serious loss, unless some other work, typical of the same method of treatment, were substituted for it. ”
