“Now, then, we get to the main point, which is: Each satisfied faculty contributes its amount of happiness in proportion to its complexity of the desire; so that a being which has numerous and complex desires, and has them all satisfied, is immeasurably happier than a being which has but a few and simple desires, which are also all satisfied. Each faculty, then, is a track, so to speak, on which loads of happiness of different value are coming into consciousness. “Now, I think we can easily see why it is that a highly enlightened person, other things being equal, is happier than an ignorant, superstitious one. The enlightened person has several advantages over the ignorant one. First, the enlightened person understands the phenomena of nature better, which enables him to march more in harmony with facts, by which he escapes the natural penalty of discord, and reaps the reward of harmony. And, secondly, the informed person lives in a vast mental world, bounded only by telescopic stars located in the remote regions of the universe. His extended world contains countless, admirable things, the admiration of each of which brings him a flood of happiness; while the unenlightened, superstitious person lives in a very contracted mental world bounded by superstitious fear, over which boundary he dares not pass. His small world contains only a few things from which he receives happiness by admiring them, and even these few things he understands so imperfectly that he is continually punished by nature for running cross-grained with facts. The foregoing conclusion is also confirmed by the evolution point of view. For if the greatest happiness is our highest aim and end, a complex being could not have evolved from a simpler one, if the complex organism were not enjoying a greater happiness than the more ignorant or inferior one.
