Comment: Ontological Commitment (Score 1) 559
Bear in mind that the theists are just as strong in their beliefs as the atheists, but neither can prove their belief either way and must rely on faith.
But atheists are not trying to prove that gods do not exist. They simply lack belief in the existence of gods. If we lay out the interesting options in doxastic logic they are:
1. p:G - a person has belief in the existence of gods
2. p:~G - a person has belief in the non-existence of gods
3. ~p:G - a person lacks belief in the existence of gods
Of these, the first probably does not exist since the majority of believers either believe only in a single or a particular panoply of gods. They are making an ontological commitment and they have a burden of proof to demonstrate the existence of the particular god or gods they believe in.
The second sentence is probably fairly rare. Again they are making an ontological commitment and must demonstrate that no god exists. Since it is impossible to prove an open-ended negative like this they are in a difficult position (what about the god that the sentient gas bags of an unnamed planet in IOK-1 worship).
The third is the majority atheist position. It doesn't make an ontological commitment, it is merely sceptical of the evidence that believers supposedly have for the existence of the particular deities they worship.
