'''Agnosticism''' is , in weaker forms, an affirmation of ignorance regarding the existence of God, and in stronger forms, the belief assertion that [[God]]'s existence or non existence is not capable of being known (unknowable). However The proponent of the weaker form does not make a claim to knowledge about existence, when speaking informally many people use ''agnostic'' but it is simply a possibly humble suspension of decision. A suspension of decision, in terms of logic, does not have a truth value, and therefore is not an argument. The proponent of the stronger form goes a step further and makes a claim to mean "undecided" about knowledge by saying, ''I know that the existence of Godcannot be known's '. However, the stronger form does have a truth value, and therefore can be right or wrong. Either what the proponent of stronger agnosticism is correct that the existenceof God is not capable of being known, without implying anything about our ability to know for sureor he is incorrect.
The word "agnostic" was coined in 1869 by [[T. H. Huxley]]<ref>T. H. Huxley was also an early and influential supporter of Darwinism.</ref> from the Greek roots ''a-'' not, and ''-gnostic,'' knowing; the philosopher [[Herbert Spencer]] was influential in spreading its use. One nineteenth-century saw held that "There is no god but the Unknowable, and Herbert Spencer is his prophet."<ref>London, Jack (1913), ''Martin Eden,'' [http://london.sonoma.edu/Writings/MartinEden/chapter13.html Chapter 13]</ref> [[David Hume]] and [[Bertrand Russell]] were famous agnostics. Two present famous agnostics are [[Larry King]] and [[Fidel Castro]].
