On science and good life
There is probably no limit to what science can do in the way of increasing positive excellence. Health has already been greatly improved; in spite of the lamentations of those who idealize the past, we live longer and have fewer illnesses than any class or nation in the eighteenth century. With a little more application of the knowledge we already possess, we might be much healthier than we are. And future discoveries are likely to accelerate this process enormously.
So far, it has been physical science that has had most effect upon our lives, but in the future physiology and psychology are likely to be far more potent. When we have discovered how character depends upon physiological conditions, we shall be able, if we choose, to produce far more of the type of human beings that we admire. Intelligence, artistic capacity, benevolence—all these things no doubt could be increased by science. There seems scarcely any limit to what could be done in the way of producing a good world, if only men would use science wisely.

To begin with, what is ‘natural?’ Roughly speaking, anything to which the speaker was accustomed in childhood. Lao-Tze objects to roads and carriages and boats, all of which were probably unknown in the village where he was born
