Atheism

Atheism is a complex term to define, and many definitions fail to capture the range of positions an atheist can hold. Perhaps the most obvious meaning to many people now is the absence or rejection of a belief in a God, or gods. However, it has been used through much of history to denote certain beliefs seen as heretical, particularly the belief that God does not intervene in the world. More recently, atheists have argued that atheism only denotes a lack of theistic belief, rather than the active denial or claims of certainty it is often associated with. This is held to follow from its etymology: it stems from the Greek adjective atheos, deriving from the alpha privative a -,'without, not', and 'theos', 'God'. It is not clear, however, that this could not equally mean 'godless' in the earlier sense as meaning a heretical or immoral person.

The exact meaning of 'atheist' varies between thinkers, and caution must always be shown to make sure that discussions of atheism are not working at cross purposes. Michael Martin, a leading atheist philosopher, defines atheism entirely in terms of belief.[1] For him, negative atheism is simply the lack of theistic belief, positive atheism is the asserted disbelief in God, and agnosticism is the lack of either belief or disbelief in God. This suggests that negative atheism, the minimal position that all atheists share, divides neatly into agnosticism and positive atheism. It is worth noting that the 'positive atheist' need not have certainty that God doesn't exist: it is a matter of belief, not knowledge.
