I've never heard of passing the salt as a superstition. What if someone across the table wants the salt. Is he/she supposed to get it themselves?

It wouldn't suprise me if it is superstitious though.
I just think the two issues of humanity's apparent irrationality and superstitions only appear in my mind as problematic because I guess I'm viewing superstition as traditionally opposed to rationality. I don't mean that it's rational to believe in auras or to carry a certain object or to wear certain clothing, but I just think the relationship between reason and superstition is more complex than mere opposition. I do think we're all superstitious to an extent, but at the same time I think superstitious beliefs are simply the very opposite of reason. I myself try to reject superstitious beliefs when they become exposed, because to me it becomes somewhat a pattern of irrationality.
