Perhaps this poor scientist never had money enough to marry even, and lives very simply. May be, the dog laughs at him. But the scientist says, "My dear dog, your pleasure is only in the senses which you enjoy, and you know nothing beyond; but for me this is the most enjoyable life, and if you have the right to seek your pleasure in your own way, so have I in mine." The mistake is that we want to tie the whole world down to our own plane of thought and to make our mind the measure of the whole universe. To you, the old sense-things are, perhaps, the greatest pleasure, but it is not necessary that my pleasure should be the same, and when you insist upon that, I differ from you. That is the difference between the worldly utilitarian and the religious man. The first man says, "See how happy I am. I get money, but do not bother my head about religion. It is too unsearchable, and I am happy without it." So far, so good; good for all utilitarians. But this world is terrible. If a man gets happiness in any way excepting by injuring his fellow-beings, godspeed him; but when this man comes to me and says, "You too must do these things, you will be a fool if you do not," I say, "You are wrong, because the very things, which are pleasurable to you, have not the slightest attraction for me. If I had to go after a few handfuls of gold, my life would not be worth living!
