Negative and Positive Atheism - Scope of Application

Scope of Application

Because of flexibility in the term god, it is possible that a person could be a positive/strong atheist in terms of certain conceptions of God, while remaining a negative/weak atheist in terms of others. For example, the God of classical theism is often considered to be a personal supreme being who is omnipotent, omniscient, omnipresent, and omnibenevolent, caring about humans and human affairs. One might be a positive atheist for such a deity (see problem of evil), while being a negative atheist with respect to a deistic conception of God by rejecting belief in such a deity but not explicitly asserting it to be false.

Positive and negative atheism are distinct from the philosopher George H. Smith's less-well-known categories of implicit and explicit atheism, also relating to whether an individual holds a specific view that gods do not exist. "Positive explicit" atheists assert that it is false that any deities exist. "Negative explicit" atheists assert they do not believe any deities exist, but do not assert it is true that no deity exists. Those who do not believe any deities exist, but do not assert such non-belief, are included among implicit atheists. Among "implicit" atheists are thus sometimes included the following: children and adults who have never heard of deities; people who have heard of deities but have never given the idea any considerable thought; and those agnostics who suspend belief about deities, but do not reject such belief. All implicit atheists are included in the negative/weak categorization.

Under this positive/negative classification, some agnostics would qualify as negative atheists. The validity of this categorization is disputed, however, and a few prominent atheists such as Richard Dawkins avoid it. In The God Delusion, Dawkins describes people for whom the probability of the existence of God is between "very high" and "very low" as "agnostic" and reserves the term "strong atheist" for those who claim to know there is no God. He categorizes himself as a "de facto atheist" but not a "strong atheist" on this scale. Within negative atheism, philosopher Anthony Kenny further distinguishes between agnostics, who find the claim "God exists" uncertain, and theological noncognitivists, who consider all talk of gods to be meaningless.
