It is very easy to imagine something, speculate something, think about something, or propose something. It is also easy to doubt something that defies common sense if there is no consequence for it. It is much harder to act on it. As Peirce would say, “Let us not pretend to doubt in philosophy what we do not doubt in our hearts.”
Many hypotheses in philosophy, because they contain no immediate consequence for believing in them, are easily proposed and speculated upon. But would anyone act on them given a punishment?
Suppose you were proposed the question: “Is the world a simulation?” If you were right, you go to a blissful paradise for eternity. If you were wrong, you would be entered into an eternal pit of fire. Would any person bet “yes”? Would you bet yes for the question “Is naturalism true?”, “Are other minds real?”, “Does consciousness supervene on the physical?” etc etc?
Whichever way you bet, is the alternative really an actual belief of yours or just mental masturbation? Does imagining consequences, for lack of a better term, help you cut through the bullshit of your own mind?
