Wikipedia to the rescue. http://en.wikipedia.org/wiki/Theory_of_justification http://en.wikipedia.org/wiki/Theory_of_justification Basically, a belief is justified if there are good reasons for believing it. What are "good" reasons? It depends on your philosophy. But presumably the reasons are separate from the belief its self. If you cite certain reasons for believing one thing, but then refuse to believe something else on the same basis, you're being inconsistent.
