Agnosticism is most generally the positive belief (rather than a lack of belief) that it is '''impossible''' to know whether there is a deity. Literally, its etymology means "ignorant," of course, but etymology is not always the only means of knowing the way a word is currently used. (''Let'', for instance, has meant both "prevent" and "allow" in the history of English.)
''Agnostic'' is also used to refer to not having come to a conclusion, i.e., "I don't know." (Whether evidence has been examined it is beside the point.) This is not the same as "One cannot know," which is the stricter and probably more common use of the term. —[[User:ASDamick|<font size="3.5" color="green" face="Adobe Garamond Pro, Garamond, Georgia, Times New Roman">Fr.
