“Happily men don't realise how stupid they are, or half the world would commit suicide. Knowledge is a will-of-the-wisp, fluttering ever out of the traveller's reach; and a weary journey must be endured before it is even seen. It is only when a man knows a good deal that he discovers how unfathomable is his ignorance. The man who knows nothing is satisfied that there is nothing to know, consequently that he knows everything; and you may more easily persuade him that the moon is made of green cheese than that he is not omniscient.”

“The rhetorician need not know the truth about things; he has only to discover some way of persuading the ignorant that he has more knowledge than those who know.”

“A man who knows how little he knows is well, a man who knows how much he knows is sick. If, when you see the symptoms, you can tell, Your cure is quick.A sound man knows that sickness makes him sick and before he catches it his cure is quick.”

“Only a blind man can easily define what light is. When you do not know, you are bold. Ignorance is always bold; knowledge hesitates. And the more you know, the more you feel that the ground underneath is dissolving. The more you know, the more you feel how ignorant you are.”

“There are few things more dreadful than dealing with a man who know that he is going under in his own eyes, and in the eyes of others. Nothing can help that man.”

“They ascribe omnipotence and omniscience to him and I don't know what else; it seems to me so strange that they never credit him with common-sense or allow him tolerance. If he knew as much about human nature as I do he'd know how weak men are and how little control they have over their passions, he'd know how full of fear they are and how pitiful, he'd know how much goodness there is even in the worst and how much wickedness in the best. If he's capable of feeling he must be capable of remorse, and when he considers what a hash he's made in the creation of human kind can he feel anything but that? The wonder is that he does not make use of his omnipotence to annihilate himself. Perhaps that's just what he has done.”
