An example for Alexandre: In the past there have been all sorts of models of the cosmos proposed. One of them was that of the familiar (to us) celestial sphere. Later on it was replaced by better knowledge leading to our present ideas. However regardless of "Truth" the celestial sphere model remains a useful one for our purposes. An irony came home to me when I read that some scientists think that if we could travel away from Earth in a straight line far enough we might arrive back here again - so if there is some "Truth" there, a version of the celestial spere may indeed have validity. As another model. "Truth", bless its little soul (!), remains elusive ... > Mike Hannibalwrote: > > Hi Alexandre, > > I'll try to avoid the labels > > I think that you mistake my point: I agree violently > with you about the value that science has delivered. > Yes life expectancy increased by about 35 years during > the course of last century.
