Now I'm just bouncing off of your reply, which really got my gears turning but I sort of see the Dunyain's dedication to the Logos as their form of "worship". Granted, they don't (or at least I'm not aware of) worship in the traditional sense. But the pursuit of the Logos seems to be kind of self contradictory in a way.
They see men as puppets that adhere to cultural norms that have been dictated by their social norms and influences. The Dunyain are looking for that self moving thought. Doesn't the fact that the Dunyain still search for that thought fall into the category of a "culture" for them? In a sense because they are born into the society of the Dunyain and pass their tests, they become part of the culture that searches for the escape of mass social thought. Obviously they can influence lesser men to the extent we can a child, but the Dunyain society just seems like a more advanced form of social culture that merely has a singular goal instead of a sea of goals (like normal society).
Now in contrast, in the case of the White Luck Warrior he appears to be merely an extension of someone else's will. He is merely there to carry out a purpose. In a sense he seems to be the purest form of what the Dunyain look down upon. A puppet with no self moving thought or desire that is his own. He is absent from the mass desires of culture because he is the embodiment of a will of someone (or something) else.
I'm a bit rusty still in my Dunyain study, as I'm only only my second read through lol so I'm most likely just swinging for the fences with ridiculous speculation.
