Ethical naturalism encompasses any reduction of ethical properties, such as 'goodness', to non-ethical properties; there are many different examples of such reductions, and thus many different varieties of ethical naturalism.

. Garner and Rosen say that a common definition of "natural property" is one "which can be discovered by sense observation or experience, experiment, or through any of the available means of science." They also say that a good definition of "natural property" is problematic but that "it is only in criticism of naturalism, or in an attempt to distinguish between naturalistic and nonnaturalistic definist theories, that such a concept is needed."
R. M. Hare
Richard Mervyn Hare (21 March 1919 – 29 January 2002), usually cited as R. M. Hare, was a British moral philosopher who held the post of White's Professor of Moral Philosophy at the University of Oxford from 1966 until 1983. He subseque ...
also criticised ethical naturalism because of what he considered its fallacious definition of the terms 'good' or 'right', saying that value-terms being part of our prescriptive moral language are not reducible to descriptive terms: "Value-terms have a special function in language, that of commending; and so they plainly cannot be defined in terms of other words which themselves do not perform this function".

like Ronald A. Lindsay have counter-argued that their way of understanding "morality" as a practical enterprise is the way we ought to have understood it in the first place. He holds the position that the alternative seems to be the elaborate philosophical reduction of the word "moral" into a vacuous, useless term.

have settled on the idea that one cannot derive ''ought'' from ''is''. Conversely, Harris maintains that the fact-value distinction is a confusion, proposing that values are really a certain kind of fact. Specifically, Harris suggests that values amount to empirical statements about "the flourishing of conscious creatures in a society". He argues that there are objective answers to moral questions, even if some are difficult or impossible to possess in practice. In this way, he says, science can tell us what to value. Harris adds that we do not demand absolute certainty from predictions in physics, so we should not demand that of a science studying morality (see ''
