Would not a serious attempt to answer that question have to first acknowledge that language carries with itself the problem?

In fragmentary perception 'I' have a 'problem' (with this or that). So that affirmation already contains the horizontal conflict (the subject vs the object). 

So firstly we see that we must be very careful with language.

The thinker and (his) thoughts.

But when it is attempted without effort to perceive everything perceivable at the same time, including thought, in this true factual perception there is no thinker.

There is no thinker, only thought. The fact is that the thinker is the product of thought. 

This is not just a conclusion (knowledge) but an observable fact.

And what is the pillar of the human society? And what an enormous structure was built on the illusion?

Do we see the consequences?
