 He did not, however, define “agnosticism” simply as the state of being an agnostic. Instead, he often used that term to refer to a normative epistemological principle, something similar to (though weaker than) what we now call “evidentialism”. Roughly, Huxley’s principle says that it is wrong to say that one knows or believes that a proposition is true without logically satisfactory evidence (Huxley 1884 and 1889). But it was Huxley’s application of this principle to theistic and atheistic belief that ultimately had the greatest influence on the meaning of the term. He argued that, since neither of those beliefs is adequately supported by evidence, we ought to suspend judgment on the issue of whether or not there is a God.
