I dont think the idea is that anyone who wants to stop war is stupid ... its that anyone who thinks war is necessary clearly does not see that the diversity of viewpoints exists and that others viewpoints are just as valid as theirs (as hard as it may be to understand) and deserves respect.

I do not think that is what Gurdjieff meant. The idea that all viewpoints are valid could hardly be more alien to his system. From my reading of Gurdjieff, I take him to be speaking here of the mechanical nature of the ordinary man, who imagines himself to be thinking and acting, an idea contradicted as soon as one observes him in his life.
