know well, are the desire to live and the desire to know. We find this in Genesis: God: i. e., the clerics, was angry because his creatures ate of these different fruits. God's comprehension of the danger of the tree of life is not wonderful, but his foreseeing of the danger of the tree of knowledge was extraordinary foreseeing, for very little of the fruit of this tree had been eaten at the time the text was written. All through the Middle Ages the clerics strove to keep men from it with tortures and burnings at the stake, and they were so anxiously striving for success in protecting their flocks from this tree that they allowed the sheep to wander, the rams to follow the ewes, and to gambol as they pleased. But the efforts of the clerics were vain. There were rams who renounced the ewes, and the succulent herbage that grows about the tree of life, for the sake of the fruit of the tree of knowledge; all the fences that the clerics had erected were broken down one by one; and during the nineteenth century a great feast was held under the tree. But after every feast there are always ailing stomachs; these denouncing the feast go about in great depression of spirit, surfeited feasters, saying the branches of the tree have been plucked bare; others complain they have eaten bitter fruit. This is the moment for the prowling cleric. Hell is remote, it has been going down in the world for some time, and biology, if no conclusions be drawn, serves the clerical purpose almost as well. "The origins of existence are humble enough, my son, but think of the glorious heritage," and the faint-hearted sheep is folded again.... The tree of life is more abundant; whenever a fruit is plucked another instantly takes its place, and all the efforts of the clerics are now directed to keep their flocks from this tree. "Back to the tree of knowledge!" they cry. "Hu! Hu! Hu! Both trees," they mutter among themselves, "are accursed, but this one, from which sweet fruit may always be plucked, is the worser." And they collect together in groups to pass censure on their predecessors. "My predecessors were infallible fools," cries the Pope, "to have permitted praise of this fatal tree, wasting their energies on such men as Bruno, who said the earth was round, and Galileo, whom they forced to say he was mistaken when he said the earth moves. A pretty set of difficulties they have involved us in with their accursed astronomy. Boccaccio and the Troubadours should have been burned instead, and if this had been done all the abominable modern literature which would persuade the faithful that this world is not all sackcloth and ashes would never have been written. Away with him who says that the earth is as beautiful as heaven," and Gautier's phrase, _"Moi, je trouve la terre aussi belle que le ciel, et je pense que la correction de la forme est la vertu,"_ has become the heresy more intolerable than any other to the modern cleric, and to me and to all the ardent and intellectual
