I took a few philosophy classes. I found it incredibly valuable in identifying assumptions and testing them.

Being Christian, it helped me understand what I believe and why. It made faith a deliberate, reasoned choice.

And, of course, there are many rational reasons for people to have very different opinions when it comes to religion and deities.

Being bipolar might give me an interesting perspective. Everything I’ve read about rationalists misses the grounding required to isolate emotion as a variable.
