Intrinsic and extrinsic properties (philosophy)

An intrinsic property is a property that an object or a thing has of itself, independently of other things, including its context. An extrinsic (or relational) property is a property that depends on a thing's relationship with other things. For example, mass is an intrinsic property of any physical object, whereas weight is an extrinsic property that varies depending on the strength of the gravitational field in which the respective object is placed. As such, the question of intrinsicality and extrinsicality in empirically observable objects is a significant field of study in ontology, the branch of philosophy concerned with explaining the fundamental nature of being.

David Lewis offered a list of criteria that should condense the distinction between intrinsic and extrinsic properties (numbers and italics added):

Intrinsic properties are fundamental in understanding Kantian deontological ethics, which is based upon the argument that an action should be viewed on its intrinsic value (the value of the action in itself) with regard to ethics and morality, as opposed to consequentialist utilitarian arguments that an action should be viewed by the value of its outcomes.

Intrinsicism is the belief that value is a non-relational characteristic of an object. This means that an object can be valuable or not, good or bad, without reference to who it is good or bad for, and without reference to the reason it is good or bad. One example of this might be the belief that certain sex acts are intrinsically evil, even if they harm no one.

Extrinsicism is the tendency to place major emphasis on external matters rather than on more profound realities. In terms of morals and ethics, it tends to stress the external observance of laws and precepts, with lesser concern for the ultimate principles underlying moral conduct.
