Dictionary Definitions of Atheism
Variations throughout the last 100 years

      The definitions on this page use the word "disbelieve" when defining atheism. People ignore this word and move right along to the secondary sense of "denial." When we take a closer look at the word "disbelieve," however, we find two senses: an active and a passive.

      1. In the passive sense, "disbelieve" simply means "not believe." This is the broadest sense of atheism, lacking belief in any gods.

      2. In the active sense, "disbelieve" involves deliberately refusing to believe something. Once again, however, this is not the same as asserting that the claim is false and represents a slightly narrower version of weak atheism.

      The definition of atheism, encompasses both the "weak" and the "strong" senses of atheism used today.
