Knowledge is as wings to man’s life, and a ladder for his ascent. Its
acquisition is incumbent upon everyone. The knowledge of such sciences,
however, should be acquired as can profit the peoples of the earth, and not
those which begin with words and end with words. Great indeed is the claim of
scientists and craftsmen on the peoples of the world…. In truth, knowledge
is a veritable treasure for man, and a source of glory, of bounty, of joy, of
exaltation, of cheer and gladness unto him. Thus hath the Tongue of Grandeur
spoken in this Most Great Prison.
