But those who have struggled to obtain
a deeper knowledge of the physical sciences and who, therefore, know enough to retain
their sense of proportion and judgment know that the vast unknown is ever so much more
than what is known and that while human intelligence may bring under its domain more and
more as time goes on, there is a residue that cannot be either ignored or brought under
the sway of man's intelligence.
Men of science not only preserve their
humility but, on account of their very knowledge of some of the secrets of nature,
contemplate with increased humility and reverence that which must ever remain outside the
pale of human analysis. The cause of all causes, the law of all laws cannot be
seized by the highest effort of human reasoning or investigation. Human reason is so
perfectly fashioned and rounded off that there is no room for any sense of limitation.
