The term axiology comes from the French "axiologie" and this derives from the Greek "ἄξιος" which means "with value" or "worthy" and "logos" which means "treaty", in addition to the suffix "ia" which indicates quality, in antiquity referred to the "study of what is worthy" or "treaty of what is valuable or worthy"; With the passage of time its terminology was changing to finally mean "the theory or the study of values." Axiology is that part of the field of philosophy that orders and focuses on the study of the nature of values and evaluative judgments. According to sources, the word axiology was implemented for the first time by the French Paul Lapie in 1902in his work Logique de la volonté; to later be used by the German-German Eduard Von Hartmann in his work Grundriss der Axiologie in 1908.
Then it can be said that axiology is the study of value, or goodness, in its broadest sense. The distinction is commonly made between intrinsic and extrinsic value, that is, between what is valuable in and of itself and what is valuable only as a means to something else, what may be extrinsically or intrinsically valuable. According to the nature of axiology there are two philosophical currents that are idealism, where there is the objective idealism that is believed that value is outside of people or things and the subjective idealism that it is believed that value can be found in the consciousness of the individual. And the philosophical current of materialism exposes that the nature of value resides and depends on the capacity of each individual to value what surrounds him in an objective way.
It should be noted that axiology and deontology are the most important branches of philosophy that contribute to ethics, which is one of the general branches of this.
