“Cease, every joy, to glimmer on my mind,
But leave, oh! leave the light of Hope behind!”

Context: Man, in the long ages since he descended from the trees, has passed arduously and perilously through a vast dusty desert, surrounded by the whitening bones of those who have perished by the way, maddened by hunger and thirst, by fear of wild beasts, by dread of enemies, not only living enemies, but spectres of dead rivals projected on to the dangerous world by the intensity of his own fears. At last he has emerged from the desert into a smiling land, but in the long night he has forgotten how to smile. We cannot believe in the brightness of the morning. We think it trivial and deceptive; we cling to old myths that allow us to go on living with fear and hate – above all, hate of ourselves, miserable sinners. This is folly. Man now needs for his salvation only one thing: to open his heart to joy, and leave fear to gibber through the glimmering darkness of a forgotten past. He must lift up his eyes and say: "No, I am not a miserable sinner; I am a being who, by a long and arduous road, has discovered how to make intelligence master natural obstacles, how to live in freedom and joy, at peace with myself and therefore with all mankind." This will happen if men choose joy rather than sorrow. If not, eternal death will bury man in deserved oblivion.

Context: When the flush of a new-born sun fell first on Eden's green and gold,
Our father Adam sat under the Tree and scratched with a stick in the mould;
And the first rude sketch that the world had seen was joy to his mighty heart,
Till the Devil whispered behind the leaves, “It's pretty, but is it Art?”
