I'm not sure I understand what people mean when they ask, in adecontextualized way, "whether something matters". It seems likewhether something matters to you depends on what your project or goal is at themoment. If you're doing your laundry, it matters that you've gotdetergent, whereas that doesn't really matter if what you're trying to do is prepare dinner. Are there projects for which God's existence does matter? Some people think that if you're reflecting on how one oughtto act, God's existence matters a whole lot. Elsewhere here ,DavidBrink argues that that isn't so, that God's existence doesn'treally matter as far as moral issues are concerned. Still, it seemsthat there are projects relative to which it does matter whether God exists. For instance, if I'm striving to devote mylife to theservice of God, then it should matter a very great deal to me whether Godexists; it matters enormously, for if He doesn't exist then that projectsimply cannot be carried out.

Is this another way of asking whether belief in the existence of Godmust be irrational in light of God's intangibility? If so, I wouldanswer No. There are many things that I cannot touch in whoseexistence I believe. For instance, I believe in the existence of Mars,but I'll never touch it. You might think that's a bad example because,while I can't actually touch Mars, I could in principle touch it: intheory, I could build a space ship that will bring me to Mars. God, onthe other hand, seems to be something that I couldn't even in principletouch: according to many, God simply isn't located anywhere in thephysical universe. But don't we believe in the existence ofintangible things even in that stronger sense of "intangible"? Forinstance, most of us believe that the Equator exists, but it's nottangible (you can't trip over the Equator). Or, to take Richard's example , we all believe that the play A Comedy of Errors exists, even though it can't be touched, ripped up, or burned. Orfinally, most of...
