Formal axiology, as does every scientific system, stems from the unfolding of its axiom or axioms. The axiom of formal axiology is the following: Value is the degree in which a thing fulfills the attributes contained in the intension of its concept. "Fulfillment" means the possession by a thing of a set of properties corresponding to the set of attributes in the intension of its concept. A thing is good if it possesses all the properties in question. The development of (...) this axiom constitutes an axiological system, which establishes the dimensions of value, a hierarchy of value, a language of value and a logic of value. (shrink)
