“Extreme intelligence is accused of being as foolish as extreme lack of it; only moderation is good. The majority have laid this down and attack anyone who deviates from it towards any extreme whatever. I am not going to be awkward, I readily consent to being put in the middle and refuse to be at the bottom end, not because it is the bottom but because it is the end, for I should refuse just as much to be put at the top. It is deserting humanity to desert the middle way. The greatness of the human soul lies in knowing how to keep this course; greatness does not mean going outside it, but rather keeping within it.”

“I do not admire the excess of a virtue as of valour, except I see at the same time the excess of the opposite virtue, as in Epaminondas, who had the greatest valour and the greatest kindness. For otherwise it is not to rise, it is to fall. We do not display greatness by going to one extreme, but in touching both at once, and filling all the intervening space.”

“The world is a good judge of things, for it is in natural ignorance, which is man's true state. The sciences have two extremes which meet. The first is the pure natural ignorance in which all men find themselves at birth. The other extreme is that reached by great intellects, who, having run through all that men can know, find they know nothing, and come back again to that same ignorance from which they set out; but this is a learned ignorance which is conscious of itself. Those between the two, who have departed from natural ignorance and not been able to reach the other, have some smattering of this vain knowledge and pretend to be wise. These trouble the world and are bad judges of everything. The people and the wise constitute the world; these despise it, and are despised. They judge badly of everything, and the world judges rightly of them.”

“When I see the blind and wretched state of men, when I survey the whole universe in its deadness, and man left to himself with no light, as though lost in this corner of the universe without knowing who put him there, what he has to do, or what will become of him when he dies, incapable of knowing anything, I am moved to terror, like a man transported in his sleep to some terrifying desert island, who wakes up quite lost, with no means of escape. Then I marvel that so wretched a state does not drive people to despair.”

“When I consider the short duration of my life, swallowed up in the eternity before and after, the little space which I fill, and even can see, engulfed in the infinite immensity of spaces of which I am ignorant, and which know me not, I am frightened, and am astonished at being here rather than there; for there is no reason why here rather than there, why now rather than then. Who has put me here? By whose order and direction have this place and time been allotted to me? Memoria hospitis unius diei prætereuntis.”

“Once that is clearly understood, I think that each of us can stay quietly in the state in which nature has placed him. since the middle station allotted to us is always far from the extremes, what does it matter if someone else has a slightly better understanding of things? If he has, and if he takes them a little further, is he not still infinitely remote from the goal? Is not our span of life equally infinitesimal in eternity, even if it is extended by ten years?In the perspective of all these infinites, all finites are equal and I see no reason to settle our imagination on one rather than another. Merely comparing ourselves with the finite is painful.”

“It is superstitious to put one's hope in formalities, but arrogant to refuse to submit to them.”
