Really saying they disagreed about spirit is not helping say they aren't irrational. A belief in a spirit is still irrational in the sense that there is no evidence for it. There's not even any way for a spirit to have any meaningful impact in the physical world.
"If all mankind minus one, were of one opinion, and only one person were of the contrary opinion, mankind would be no more justified in silencing that one person, than he, if he had the power, would be justified in silencing mankind."
~John Stuart Mill~
