You can tell a good deal about a person by learning what they consider to be legitimate means of knowing anything.

If they indicate that anything other than observation and reason is a reliable means of knowing then you are dealing with a religious or mystical person.

Man's only means of knowing anything at all is through the use of his five senses to observe reality and then his faculty of reason to understand that which he has observed.

Almost all violence is committed by people who believe that there are alternate means of knowing. This correlation is not simply a coincidence.

From the 9/11 terrorists to fanatical fundamentalist Christians, they all consider revelation a legitimate epistemological method.

Another false epistemological method is that of emotions. If a person feels something is right then they consider that knowledge and act accordingly.
