B. History (Contd)
  • His commitment to the scientific method is
    seen in the following quote I believe, in a
    word, that the true scientific method confines
    the mind without suffocating it, leaves it as far
    as possible face to face with itself, and guides
    it, while respecting the creative originality and
    spontaneity which are its most precious
    qualities..
