Agnosticism
Agnosticism is the view or belief that the existence of God, of the divine or the supernatural is unknown or unknowable.[1][2][3] Another definition provided is the view that "human reason is incapable of providing sufficient rational grounds to justify either the belief that God exists or the belief that God does not exist."[2]
Not to be confused with Gnosticism.The English biologist Thomas Henry Huxley coined the word agnostic in 1869, and said "It simply means that a man shall not say he knows or believes that which he has no scientific grounds for professing to know or believe." Earlier thinkers, however, had written works that promoted agnostic points of view, such as Sanjaya Belatthiputta, a 5th-century BCE Indian philosopher who expressed agnosticism about any afterlife;[4][5][6] and Protagoras, a 5th-century BCE Greek philosopher who expressed agnosticism about the existence of "the gods".[7][8][9]
Ignosticism[edit]
A related concept is ignosticism, the view that a coherent definition of a deity must be put forward before the question of the existence of a deity can be meaningfully discussed. If the chosen definition is not coherent, the ignostic holds the noncognitivist view that the existence of a deity is meaningless or empirically untestable.[98] A. J. Ayer, Theodore Drange, and other philosophers see both atheism and agnosticism as incompatible with ignosticism on the grounds that atheism and agnosticism accept the statement "a deity exists" as a meaningful proposition that can be argued for or against.[99][100]
