The barrier
Philosophers and theologians have a remarkable command of the English language. They can articulate on subjects of extreme complexity and difficulty with ease. But this is not surprising, given the degree to which they have devoted their lives to the enterprise. Indeed they need to devote their lives without reserve if they are to avoid a confrontation with the absolute.
Their rationality has placed them in the proximity of truth; now they do all they can to avoid it by taking their knowledge to an extreme. They become experts at hedging around the truth and procrastination. They cannot see the wood for the trees; but this is exactly the way they want it - so they have taken it upon themselves to plant countless forests of trees, trees with all manner of impressive and difficult names - as a safeguard. You see, proximity to truth is not to be confused with closeness, for if you are even a hairsbreadth away, you are a million miles.
It is as though these scholars journeyed to the end of the earth, and on encountering the Void, a barrier they cannot pass, they decided to set up camp. Shortly, the camps became many, and eventually grew into vast and complex cities. Consequently these scholars are experts on the small patch of terrain, there at the end of the earth, but have never ventured beyond it - into the Infinite.
If they meet a true man of the void, they speak enthusaistically to him of their world and lives, but he finds it difficult to follow their speech, for he only glanced at their world in passing.
