I believe that's the second part, there is a first part although: realizing there is a problem. For example, you may not see cancer as a problem and not try to find a cure as you may see this as a special destiny.

And to help people to realize problems you need to teach them to doubt. And not only doubting about religion, but also science (didn't Eistein somehow prove Newton wrong?) and their life choises and everything basicaly.

Who is good at doubting? I believe usually really good scientists or people that have a grasp of good philosophy (the greeks, Popper, etc.).

So, as it's not even that difficult to learn, I believe the world needs more (good) philosophy...
