I think those two aproachs do not contradict. Yours is just very pragmatic and i respect it. But I think you didn't understand the aspect of rationality as distinct from capability. This would be the inability to solve world hunger despite having the means to, that is just inconsistency in making good decisions. I think your analogy with the dark room even works here. You have all the tools to make the room bright and you certainly want to be able to see, but your decisions do not consistently bring about the desired result, which is an illuminated room. Edit: Well. I tried my best to explain. But looks like you are not interested in a discussion here. I grow tired of personal attacks.
