However they do correlate to some extent with types of conscious processing described in Edelman's (1992) evolutionary theory of embodied consciousness, including perception, attention, memory (knowledge), concept formation (conception), value systems (attitude, engagement), planning (anticipation).10.10
According to the second conception, values are incommensurable if and only if there is no true general overall ranking of the realization of one value against the realization of the other value.
The authors examine the evolutionary significance of nature during childhood; the formation of children's conceptions, values, and sympathies toward the natural world; how contact with nature affects children's physical and mental development; and the educational and political consequences of the weakened childhood experience of nature in modern society.

Instead of pitting conceptions of value against conceptions of rights, it has been suggested that there may be two different conceptions of intrinsic value in play in discussion about environmental good and evil.
Concomitant with the demise of positivism and of utilitarianism in the post-war era has been the rise of analytical enquiry into non-hedonistic conceptions of value, including conceptions of meaning in life, grounded on relatively uncontroversial (but not certain or universally shared) judgments of cases, often called "intuitions".
The first conception characterizes value incommensurability in terms of restrictions on how the further realization of one value outranks realization of another value.
This third conception of value incommensurability is sometimes said to be necessary to explain why, in conflicts of value, a gain in one value does not always cancel the loss in another value.
As Brogaard points out, however, the Moorean conception of value is problematic because as Wlodek Rabinowicz & Toni Roennow-Rasmussen (1999 20033) have pointed out there seem to be objects which we value for their own sake but whose value derives from their being extrinsically related to something else that we value.
