“Whatever is true spiritually and ethically about our circumstances… there is no doubt there are spiritual truths… there are spiritual experiences human beings can have…and there are ethical truths. Whatever is true about that has to transcend culture; it has to transcend our cultural differences. 

Consequently, it makes no sense at all to have one’s spiritual life pegged to rumors of ancient miracles. What we need is a discourse about ethics and spiritual experience that is as unconstrained by ancient ignorance as the discourse of science already is. Science really does transcend the vagaries of culture.

There’s a reason why we don’t talk about Christian physics and Muslim mathematics. It’s because an experiment run here and in Baghdad actually works in both places if it’s teasing out something fundamental about the nature of the universe. That is true ethically; that is true spiritually." Sam Harris
