The enjoyments of the senses sometimes assume another phase which is dangerous and tempting. You will always hear the idea — in very old times, in every religion — that a time will come when all the miseries of life wills cease, and only its joys and pleasures will remain, and this earth will become a heaven. That I do not believe. This earth will always remain this same world. It is a most terrible thing to say, yet I do not see my way out of it. The misery in the world is like chronic rheumatism in the body; drive it from one part and it goes to another, drive it from there and you will feel it somewhere else. Whatever you do, it is still there. In olden times people lived in forests, and ate each other; in modern times they do not eat each other's flesh, but they cheat one another. Whole countries and cities are ruined by cheating. That does not show much progress. I do not see that what you call progress in the world is other than the multiplication of desires. If one thing is obvious to me it is this that desires bring all misery; it is the state of the beggar, who is always begging for something, and unable to see anything without the wish to possess it, is always longing, longing for more. If the power to satisfy our desires is increased in arithmetical progression, the power of desire is increased in geometrical progression.
