What then is man to do in this state of affairs? Is he to doubt everything, to doubt whether he is awake, whether he is being pinched or burned? Is he to doubt whether he is doubting, to doubt whether he exists?
No one can go that far, and I maintain that a perfectly genuine sceptic has never existed. Nature backs up helpless reason and stops it going so wildly astray.
Is he, on the other hand, to say that he is the certain possessor of truth, when at the slightest pressure he fails to prove his claim and is compelled to loose his grasp?
What sort of freak then is man! How novel, how monstrous, how chaotic, how paradoxical, how prodigious! Judge of all things, feeble earthworm, repository of truth, sewer of doubt and error, the glory and refuse of the universe!
Who will unravel such a tangle? This is certainly beyond dogmatism and skepticism, beyond all human philosophy. Man transcends man.

'If I had seen a miracle,' they say, 'I should be converted.' How can they be positive that they would do what they know nothing about? They imagine that such a conversion consists in a worship of God conducted, as they picture it, like some exchange or conversation. True conversion consists in self-annihilation before the universal being whom we have so often vexed and who is perfectly entitled to destroy us at any moment, in recognizing that we can do nothing without him and that we have deserved nothing but his disfavour. It consists in knowing that there is an irreconcilable opposition between God and us, and that without a mediator there can be no exchange.
