Illusions imply existence. It's not just turtles all the way down. There is truth. To deny that fact simply breaks the language you are using or the meaning of your entire conceptual framework, rendering it a nullity in a void of meaninglessness unless you have another framework that accepts objective truth to assign some meaning to it. The logic of dealing with contradictions is trivial. You do not need some grand scheme of history, cosmic struggle, or willful abandonment of responsibility, reality, or reason. You merely abandon the framework and assumption set that necessarily lead to a contradiction. Anyone who doesn't do this is fucked in the head and is an idiot and a goblin and that's clear as daylight to people who choose to fathom reality.
