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.
When used in the context of ethics, the meaning of universal refers to that which is true for "all similarly situated individuals".
In logic, or the consideration of valid arguments, a proposition is said to have universality if it can be conceived as being true in all possible contexts without creating a contradiction.
In metaphysics, a universal is a proposed type, property, or relation which can be instantiated by many different particulars.
