John William Davis

“The intension of an analytic concept arises from the abstraction of the common qualities of a group of things.”

“Intrinsic valuation is the value to be found in any uniquely individual object not subject to limitations of those values shared in common with some class of other individuals”

“Systemic value is the value of that structure of concepts by which all concepts, including those of value, are brought into a system.”

“Extrinsic value is the value objects, empirical things, have to the measure that they meet the demands of belonging to a class as determined by the intension of an analytic concept.”

“Scientific axiology arises from the unfolding of the following axiom: Value is the degree in which a thing possesses the set of qualities corresponding to the set of attributes in the intension of its concept.”
