11. It may be objected that there is no need to go beyond this world to explain how the desire of perfect happiness is not in vain. It works like the desire of the philosopher's stone among the old alchemists. The thing they were in search of was a chimera, but in looking for it they found a real good, modern chemistry. In like manner, it is contended, though perfect happiness is not to be had anywhere, yet the desire of it keeps men from sitting down on the path of progress; and thus to that desire we owe all our modern civilization, and all our hope and prospect of higher civilization to come. Without questioning the alleged fact about the alchemists, we may reply that modern chemistry has dissipated the desire of the philosopher's stone, but modern civilization has not dissipated the desire of perfect happiness: it has deepened it, and perhaps rather obscured the prospect of its fulfilment. A desire that grows with progress certainly cannot be satisfied by progressing. But if it is never to be satisfied, what is it? A goad thrust into the side of man, that shall keep him coursing along from century to century, like Io under the gadfly, only to find himself in the last century as far from the mark as in the first. Apart from the hope of the world to come, is the Italy of to-day happier than the Italy of Antoninus Pius? Here is a modern Italian's conclusion: "I have studied man, I have examined nature, I have passed whole nights observing the starry heavens. And what is the result of these long investigations? Simply this, that the life of man is nothing; that man himself is nothing; that he will never penetrate the mystery which surrounds the universe. With this comfortless conviction I descend into the grave, and console myself with the hope of speedy annihilation. The lamp goes out; and nothing, nothing can rekindle it. So, Nature, I return to thee, to be united with thee for ever. Never wilt thou have received into thy bosom a more unhappy being." (_La Nullità della Vita_. By G. P., 1882.) This is an extreme case, but much of modern progress tends this way. Civilization is not happiness, nor is the desire for happiness other than vain, if it merely leads to increased civilization. _Readings_.--St. Thomas, _C.
