Don't short change yourself, with enough time, effort and application you could still get a degree in the humanities, that's basically what they do :p

For real, philosophy was mostly around before we figured out empiricism and scientific methods. People had to think quite a lot to come up with models that made internal and validated sense even without evidence. And we still have a lot of stuff we can't test, but that we wonder about (theology, paranormal stuff, hard solipsism, "before" Big Bang, etc), we just have stricter requirements and more developed methods that we call differently.
