 Moore’s non-naturalism comprised two main theses. One was the realist thesis that moral and more generally normative judgements – like many of his contemporaries, Moore did not distinguish the two – are true or false objectively, or independently of any beliefs or attitudes we may have. The other was the autonomy-of-ethics thesis that moral judgements are sui generis, neither reducible to nor derivable from non-moral, for example scientific or metaphysical, judgements; they express a distinctive kind of objective truth. Closely connected to his non-naturalism was the epistemological view that our knowledge of moral truths is intuitive, in the sense that it is not arrived at by inference from non-moral truths but rests on our recognizing certain moral propositions as self-evident, by a kind of direct or immediate insight.
