What i am talking about is a uniting vision, a purpose that can rally people to a goal. A vision like the one that allowed Ghandi to effectively use peaceful non-cooperation as political means and to inspire generations ( i doubt a scientific exploration of social and psychological factors would have been equally effective ). A vision that is a crucial element of most revolutions in human history.
It is admittedly too the kind of vision that enabled various ideologists to drive their adherents to commit atrocities, so there are a few rather large downsides to it. Nevertheless it seems to be a major force not in the evolutionary development of humanity in a strictly biological sense, but in the social development.
The scientific method hardly can provide this. Working on observations, building hypotheses and collecting evidence supportive or contrary to them, is likely the most effective strategy so far to find out about the actual state of affairs, but with the current degree of specialisation it can only provide exaltation for the dedicated researchers in their field.
What you seem to be saying here is that people are generally motivated by ideas and rhetoric and broad sweeping visions, not by dry, boring technical facts uncovered by folks in white coats in laboratories. To which I say: ok, so what?
I think you'd be hard-pressed to find anyone, skeptic or otherwise, who doesn't think that ideas and imagination and soaring speeches and brilliant art don't have their place, that we should throw them all out and just sit around reading scientific journals in our free time.
You're confusing skepticism with some kind of nihilistic cynicism.
Do you as a skeptic or as an observer of skeptics consider this to be a completely separate realm that is outside the scope of science, as well as skepticism?
Can you find a vision, a driving force, a source of exaltation in the skeptic attitude or the scientific approach, that can appeal to not so sophisticated minds like mine, and would therefore offer a replacement?
Others have pointed out the many ways that science and skepticism and rational inquiry can lead to all sorts of exciting and inspiring things. I agree with all of that, but I'd add this: "skeptic" is not a complete description of a person.
I don't claim the title of "skeptic" myself, but even for those who do, skepticism doesn't need to be -- and probably isn't -- the sole source of inspiration, vision, and "exhaltation" as you put it. Skeptics are allowed to appreciate a brilliant speech, a fine glass of wine, and a beautiful sculpture. They're allowed to believe in and fight for causes, not related to skepticism, that they think will make the world a better place to live. They're allowed to love their children and laugh with their friends.
In a sense, asking whether skepticism will provide you with "exhaltation" is like asking whether it will provide you with oxygen. The exhaltation, like the oxygen, is available to skeptics and non-skeptics alike.
If you think that the only possible sources of exhaltation are irrational beliefs on the one hand, and skepticism on the other hand, then I really feel sorry for you.
