You can certainly side with Descartes and believe in rationalism, or you can study David Hume and understand those beliefs for what they are.

You can still have and respect beliefs, but distinguishing fact from belief is purely in the realm of philosophical debate. That doesn’t mean you have to accept absence of absolute truth or facts, but there is much we don’t know and that we think we know but we don’t, and that is logical and illogical. Life is dichotomy.
