Yeah, I'm a fan of pragmatism also. An original version of it from Charles Peirce[1], not the version that James Williams and others promoted. "It can be beneficial to believe in God in a religious society, therefore the belief is true". Doesn't it sounds silly to you? So we are coming to a question: how would you define "it works"? If management full of cargo-cultists can achieve no technical goals but they still get their salaries, does "it work" or not?
