  Philosophers such as Antony Flew and Michael Martin have contrasted positive (strong/hard) atheism with negative (weak/soft) atheism. Positive atheism is the explicit affirmation that gods do not exist. Negative atheism includes all other forms of non-theism. According to this categorization, anyone who is not a theist is either a negative or a positive atheist. Michael Martin, for example, asserts that agnosticism entails negative atheism. Agnostic atheism encompasses both atheism and agnosticism. However, many agnostics see their view as distinct from atheism.
  
  According to atheists' arguments, unproven religious propositions deserve as much disbelief as all other unproven propositions. Atheist criticism of agnosticism says that the unprovability of a god's existence does not imply an equal probability of either possibility. Australian philosopher J.J.C. Smart argues that "sometimes a person who is really an atheist may describe herself, even passionately, as an agnostic because of unreasonable generalized philosophical skepticism which would preclude us from saying that we know anything whatever, except perhaps the truths of mathematics and formal logic." Consequently, some atheist authors, such as Richard Dawkins, prefer distinguishing theist, agnostic, and atheist positions along a spectrum of theistic probability —the likelihood that each assigns to the statement "God exists".
  
  Before the 18th century, the existence of God was so accepted in the Western world that even the possibility of true atheism was questioned. This is called theistic innatism —the notion that all people believe in God from birth; within this view was the connotation that atheists are in denial. Some atheists have challenged the need for the term "atheism". In his book Letter to a Christian Nation, Sam Harris wrote:
  
  In fact, "atheism" is a term that should not even exist. No one ever needs to identify himself as a "non- astrologer " or a "non- alchemist ". We do not have words for people who doubt that Elvis is still alive or that aliens have traversed the galaxy only to molest ranchers and their cattle. Atheism is nothing more than the noises reasonable people make in the presence of unjustified religious beliefs.
