Science is about finding ever better approximations rather than pretending you have already found ultimate truth. A casual stroll through the lunatic asylum shows that faith does not prove anything.
Sorrow, terror, anguish, despair itself are often the chosen expressions of an approximation to the highest good. Our sympathy in tragic fiction depends on this principle; tragedy delights by affording a shadow of the pleasure which exists in pain. This is the source also of the melancholy which is inseparable from the sweetest melody. The pleasure that is in sorrow is sweeter than the pleasure of pleasure itself.
The fascinating thing to a dispassionate observer about the structure of life in the Soviet Union is that in their efforts to produce an unknown that we may let its ideologists call Socialism the Communist dictators have produced a brutal approximation of monopoly Capitalism, a system that has all the disadvantages of our own, with none of the palliatives which come to us from surviving competition and from the essential division of economic and political power which has so far made it possible for the humane traditions of the Western world to continue.
Free men are aware of the imperfection inherent in human affairs, and they are willing to fight and die for that which is not perfect. They know that basic human problems can have no final solutions, that our freedom, justice, equality, etc. are far from absolute, and that the good life is compounded of half measures, compromises, lesser evils, and gropings toward the perfect. The rejection of approximations and the insistence on absolutes are the manifestation of a nihilism that loathes freedom, tolerance, and equity.
Can quantum mechanics represent the fact that an electron finds itself approximately in a given place and that it moves approximately with a given velocity, and can we make these approximations so close that they do not cause experimental difficulties?
No one knows what the right algorithm is, but it gives us hope that if we can discover some crude approximation of whatever this algorithm is and implement it on a computer, that can help us make a lot of progress.
The first approximation in this future that we're looking at is that everyone will be physically well off. They will have a great abundance in material goods, and I think that will soften some of the conflicts we see now.
