Hi Phil ,
Man thanks for reading my essay and your comments. Yes, my invocation of the path integral is to be taken as a very loose metaphor -- and as you reminded me this was in fact the spirit in which Dirac put forward the idea. I could have written the whole essay without the path integral metaphor, but I wanted to bring some connection to physics into the essay. The basics thrust of the essay is that humanity should be open to trying different paths *and* then should select those paths as "best" which lead to a good outcome based on objective criteria. Also I want to emphasize the suggestion is an experimental one in that one should try these paths out on a small scale and those which prove to be good then scale up.
Physics/science for example used to be more open to trying different approaches. At the beginning of the 20th century SR, GR and QM showed that that idea that humanity almost knew all there was to know about the natural world (modulo some "i" dotting and "t" crossing) was wrong. Moreover these theories were almost immediately validated up to a certain limit by experiment. At present none of the small number of ideas of what comes next (string theory, loop quantum gravity, large/warped extra dimensions) has any unambiguous experimental support. For this reason my proposal is experimentally based -- if some societal path does not give good results based on some objective criteria it should be abandoned. A lot of bad results have occurred when people have tried to do top down social engineering and the refused to abandon a given approach when it was proven experimentally not to work e.g. Pol Pot sticking with his odd agrarian version of communism even when it was apparent to everyone that this was a very wrong path.
Anyway thanks for reading my essay and best of luck in the contest.
Doug
