|A depiction of some common types of atheism, the most common stereotype being that atheists are nihilists and don't believe in anything.|
The number of ways people label themselves or label others in respect to types or shades of disbelief in God or gods is extensive and elaborate.
Some atheist labels or statements of disbelief can be affixed with beliefs; a famous example being Thomas Jefferson, and oft-cited atheist, self-describing himself in 1819 and 1820 as an “Epicurean materialist” and moral philosopher.
work-in-progress listing of atheism “types”, types of atheism, i.e. variants of namesake disbeliefs in the existence of god, ranked generally from weak or marginal to strong or extreme, fitted loosely to the Dawkins scale, i.e. showing equivalent Dawkins number (DN) in column three:
|#||Type||DN||Examples | Description|
|Weak theist||3||Agnostic but leaning towards theism|
|e.g. Blaise Pascal, noted for Pascal's wager; DN:3.4 (estimate) |
|Pure agnostic |||4||Impartial agnostic|
|20/80 athe-agnostic||e.g. Brad Pitt, quote: "I'm probably 20 percent atheist and 80 percent agnostic." (Ѻ)|
|Agnostic soft atheist||One who is not 100% sure about a lot of things, in the universe, but is highly skeptical. (Ѻ)|
|Semi-atheist||e.g. Benedict Spinoza|
|Agnostic labeled atheist||e.g. Neil Tyson|
|Weak atheist||5||Agnostic but leaning towards atheism|
|Rumored atheist||e.g. Adolf Hitler (Ѻ) and Barack Obama|
|Crypto-atheist||e.g. Thomas Hobbes (1651) (see: atheism timeline) |
|Reluctant atheist||An atheist who is looking for good reasons to reject atheism and return to religious (e.g. Christian) heritage. (Ѻ)|
|New atheist||One who has kinship with the new four horsemen of atheism.|
|Aggressive atheist||e.g. Pat Condell (Ѻ) (Ѻ)|
|Explicit atheist||e.g. Democritus and the other Greek atomic theorists |
|Anti-theist||e.g. Christopher Hitchens (Ѻ), a DN=7 estimate ; one who believes that religion poisons everything and should therefore not just be declined but actively opposed. |
|Avowed atheist||7||e.g. Baron d’Holbach (1770) (see: atheism timeline) |
|Militant atheist||e.g. Friedrich Nietzsche (Ѻ)|
|Strong atheist||e.g. Libb Thims (Bossens, 2013) (Ѻ)|
|Staunch atheist||e.g. Ludwig Feuerbach  (Ѻ)|
|Extreme atheist | Historical||e.g. Julien la Mettrie, Ludwig Buchner, Baron d'Holach, Ludwig Feuerbach, Ludwig Buchner, Ayn Rand, and Libb Thims|
|King atheist||9||e.g. Patrick Fergus|
|Intentionally abrasive atheist||e.g. charlidog2(Ѻ)|
|Extreme atheist | Modern||10||e.g. Libb Thims (Sekhar, 2011) (Ѻ); self-assigned in 2009 as "10" on the 7-point Dawkins scale amid Moriarty-Thims debate|
