Ever since I started doubting the existence of God, I have frequently encountered confusion between the numerous labels used to describe non-theistic belief systems. This is most commonly seen between the words “atheist” and “agnostic,” both of which signify the absence of definitive belief in a deity. At first glance, the distinction may seem obvious: an atheist disbelieves the existence of God or gods, while an agnostic believes that it is impossible to know whether there is a God and thus refuses to commit to either belief system. However, in reality these two terms tend to overlap to the extent that two people holding exactly the same (non)belief may label it differently, one identifying as an agnostic and the other, an atheist. Further, one’s label of choice is heavily influenced by the public perception of these terms, the word “atheist” being the more pejorative of the two in the eyes of the public.
