feelings?

Sometimes I reflect on the many things that I have heard in sermons throughout the years. For me, that includes some time in seminary.

So, I have been wondering:

Why can I not trust my feelings but I can trust my reasoning?

I cannot recall how many times I have been told that my feelings are untrustworthy but my reasoning I can trust. (And let’s assume that hermeneutics is a form of reasoning.) But how realistic is that? Or, maybe more importantly, how human is that?

Happy to read any answers!
