A long time ago - Jan 2006 if I'm not mistaken - Alan Soble wrote (http://www.askphilosophers.org/question/875): "Finally, the heart and soul of philosophy is argument, providing reasons for claims, including claims about morality and duties. In the answer to the question above, I cannot find a shred of argument. We should also avoid, that is, pastoral or friendly counseling. Without rigor, philosophy is nothing."
That was back in the days when there was routinely more than 1 response to a question. Today's responses seem more and more to be becoming "pastoral or friendly counseling" without rigor. The panelists do not argue with each other - the responses are just accepted.
Here's an example: Peter Smith wrote very recently (http://www.askphilosophers.org/question/2823): "For irrationally formed beliefs are not likely to lead to actions which get any of us what we want -- including a decent life, lived well in the knowledge of our all-too-explicable mortality." This statement - simply put out...
Your comment on Peter Smith's claim, "utterly preposterous," doesn't sound like rigorous argument to me, but more like contemptuous dismissal. I'm glad panelists aren't displaying more of your style of rigor! The consideration you do offer seems to misunderstand Smith's claim. What you quote him as saying is that if our actions are guided by beliefs that have been irrationally formed, it's likely that those actions will not promote our ends. I can see why he says this: if you think (1) that irrationally formed beliefs are as likely as not to be false and (2) that actions guided by false beliefs are not likely to get us what we want, his claim follows. Your observation – that we sometimes take pleasure in beliefs even if they have been irrationally arrived at – seems correct but beside the point: it speaks neither to the truth of (1) nor to that of (2).
