Comment from Walter Stark PhD,
There is a most interesting essay by Rebeca Goldstein on Godel and the ‘Nature of Mathematical Truth’ at The Edge website.
It deals with the fundamental philosophical divide between those on the one side who accept that an objective reality does exist, that truth is defined by its consistency with objective reality and that beauty arises from the recognition of such truth, and those on the other who believe that reality,truth and beauty are ultimately our own constructions.
While the former pursue the discovery of truth, the latter aim to construct it in accord with whatever hopes, ideologies or ethics they deem desirable.
This same division seems to underlie much of my own dissention from various mainstream environmental concerns. What to the constructionists is a righteous crusade for the betterment of humankind appears to the realist an ugly disregard for truth and reality.
As for reality itself the SF writer Philip K. Dick said it well, “Reality is that which, when you stop believing in it, doesn’t go away.”
