Faust: So still I seek the force, the reason governing life’s flow; and not just its external show.
Devil: The governing force? The reason? Some things cannot be known; they are beyond your reach even when shown.
Faust: Why should that be so?
Devil: They lie outside the boundaries that words can address; & man can only know those thoughts which language can express.
Faust: What? Do you mean that words are greater yet than man?
Devil: Indeed they are.
Faust: Then what of longing, affection, pain or grief. I can’t describe these, yet I know they are in my breast. What are they?
Devil: Without substance, as mist is.
Faust: In that case man is only air as well.  [reads] What has made me thirst then to be instructed in those things that are more than thirst allows?
Devil: Your thirst is artificial, fostered by the arrogance in you. So look no further than all your human brothers do: sleep, eat, drink, and let that be sufficient.
Faust: Liar and foul traitor, where are the pulse and core of nature you promised to reveal? Where?
Devil: Faustus, you lack the wit to see them in every blade of grass.
