Rhetoric documentary is persuasive and bases its arguments on beliefs, however to believe something does not make it truth. There is a lot of grey area in what is considered ‘fiction’ in documentary for this very reason. When does something become false? Is it the same as not being entirely true?

To justify a belief does not require proof, all it requires is an explanation. To say that you hold a certain belief because it is what your parents believe is all that is needed to support your belief, because that is why you believe it. To justify knowledge, however, proof is needed, facts are needed. To know something and to believe something are two very different things.

If a documentary is based upon a belief, how can in be accepted as a fact or knowledge?
