First off, I think we have to take Jasper's General Axioms or else we have a complete mess. So assume those.

Second, I will assume that I am able to perceive and understand the world around me. If not, then what's the damn point? I cannot do without this one. I'll add to this that other people are what they seem, and can also perceive and understand the world as well (generally speaking) as I can.

Also, I will say that races, ethnicities, nationalities, and genders all have equal value and skills.

Just this much implies that there is value/usefulness in exploring and discussing the world around us. The centuries-long dialogue about the meaning of life has truth in it. Further, this casts strong suspicion on any religion which has as a tenet that one people group is superior. Suppose there is a God, why would He "reveal Himself" to only one group of people if they are all equal? He would not.

I've got more, but I'll stop here for now and see if anyone would like to comment.
