I treat it all as fake. When I avoid sticking my imaginary hand in an imaginary fire, I do so to avoid the pain I would feel from doing so, and the effects it would have on my future imaginary hand. I treat my imaginary wife well, as I like it when I see her sweet imaginary smile at me.
"A wise man ... proportions his belief to the evidence."
— David Hume, An Enquiry Concerning Human Understanding, Section X, Part I.
