Emotional reasoning is considered a flawed form of reasoning because you essentially believe in something because you feel it to be true. But isn’t this the case for any question in philosophy?

For example, why do most of us believe the external world is real? I can’t think of an answer to this except the fact that it just feels obvious. But that would just be a feeling. Any other justification can be infinitely asked the question why until you arrive at certain axioms that are simply believed. But isn’t any axiom asserted simply because one feels it to be true?

Is all of philosophy a form of emotional reasoning?
