What I do mean is that all that thinking will be mere moonshine unless we realise that nothing but the courage and unselfishness of individuals is ever going to make any system work properly. It is easy enough to remove the particular kinds of graft or bullying that go on under the present system: but as long as men are twisters or bullies they will find some new way of carrying on the old game under the new system. You cannot make men good by law: and without good men you cannot have a good society.
The deep question is: Why does nature embody so much symmetry? We do not know the full answer to this question. However, we have some partial answers. Symmetry leads to economy, and nature, like human beings, seems to prefer economy. If we think of nature as a vast ongoing experiment, constantly trying out different possibilities of design, then those designs that cost the least energy or that require the fewest different parts to come together at the right time will take precedence, just as the principle of natural selection says that organisms with the best ability to survive will dominate over time. One physical principle that governs nature over and over is the “energy principle”: nature evolves to minimize energy.
