Infallibilism

Infallibilism is, in epistemology, the position that knowledge is, by definition, a true belief which cannot be rationally doubted. Other beliefs may be rationally justified, but they do not rise to the level of knowledge unless absolutely certain. Infallibilism's opposite, fallibilism, is the position that a justified true belief may be considered knowledge, even if we can rationally doubt it. Fallibilism is not to be confused with skepticism, which is the belief that knowledge is unattainable for rational human beings.
