That we shall probably never know the whole "truth" about the universe does not really matter very much; the fun comes in trying to find out. The natural pattern of current astronomy … is provided by the cryptic unity of nature itself (belief in which is the chief act of faith of the scientist) and by questions astronomers ask today, as their predecessors have done for centuries

What is the explanation of unusual phenomena in the sky (in former days, comets and supernovae; nowadays quasars and pulsars)? | How is the universe constructed and what is our place in it ? | How did the universe begin and what is its fate (and ours)? | If we were all-seeing supermen, these might appear naive and self-centred questions: there may be more significant ones which have not even occurred to us. But the human brain is itself a part of nature, fanned into existence by billions of years of sunshine acting on the molecules of the Earth. It is not perfectible in the immediate future, even if biologists should wish to alter the brain — which is a questionable ambition. What men make of the universe at large is a product of what they can see of it and of their own human nature. | p. 25
