Absolute knowledge

In philosophy, universality is the notion that universal facts can be discovered and is therefore understood as being in opposition to relativism.

In certain religions, universalism is the quality ascribed to an entity whose existence is consistent throughout the universe. This article also discusses Kantian and Platonist notions of "universal", which are considered by many to be separate notions.

When used in the context of ethics, the meaning of universal refers to that which is true for "all similarly situated individuals."Rights, for example in natural rights, or in the 1789 Declaration of the Rights of Man and of the Citizen, for those heavily influenced by the philosophy of the Enlightenment and its conception of a human nature, could be considered universal. The 1948 Universal Declaration of Human Rights is inspired by such principles.

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. Some philosophers have referred to such propositions as universalizable. Truth is considered to be universal if it is valid in all times and places. In this case, it is seen as eternal or as absolute. The relativist conception denies the existence of some or all universal truths, particularly ethical ones (through moral relativism). Mathematics is a field in which those truths discovered, in relation to the field of mathematics, are typically considered of universal scope. Though usage of the word truth has various domains of application, relativism does not necessarily apply to all of them. This is not to say that universality is limited to mathematics, for there exists a large number of people who apply the standard to philosophy, theology and beyond.
