In philosophy, universality or absolutism is the idea that universal facts exist and can be progressively discovered, as opposed to relativism, which asserts that all facts are relative to one's perspective.[1][2] Absolutism and relativism have been explored at length in contemporary analytic philosophy.
Also see Kantian and Platonist notions of "universal", which are considered by most philosophers to be separate notions.
In metaphysics, a universal is a proposed type, property, or relation which can be instantiated by many different particulars. While universals are related to the concept of universality, the concept is importantly distinct; see the main page on universals for a full treatment of the topic.
