In the course of this Address I have touched on debatable questions and led you over what will be deemed dangerous ground--and this partly with the view of telling you that as regards these questions science claims unrestricted right of search. It is not to the point to say that the views of Lucretius and Bruno, of Darwin and Spencer, may be wrong. Here I should agree with you, deeming it indeed certain that these views will undergo modification. But the point is, that, whether right or wrong, we ask the freedom to discuss them. For science, however, no exclusive claim is here made; you are not urged to erect it into an idol. The inexorable advance of man's understanding in the path of knowledge, and those unquenchable claims of his moral and emotional nature which the understanding can never satisfy, are here equally set forth. The world embraces not only a Newton, but a Shakespeare--not only a Boyle, but a Raphael--not only a Kant, but a Beethoven--not only a Darwin, but a Carlyle. Not in each of these, but in all, is human nature whole. They are not opposed, but supplementary--not mutually exclusive, but reconcilable. And if, unsatisfied with them all, the human mind, with the yearning of a pilgrim for his distant home, will turn to the Mystery from which it has emerged, seeking so to fashion it as to give unity to thought and faith; so long as this is done, not only without intolerance or bigotry of any kind, but with the enlightened recognition that ultimate fixity of conception is here unattainable, and that each succeeding age must be held free to fashion the Mystery in accordance with its own needs--then, casting aside all the restrictions of Materialism, I would affirm this to be a field for the noblest exercise of what, in contrast with the _knowing_ faculties, may be called the _creative_ faculties of man. 'Fill thy heart with it,' said Goethe, 'and then name it as thou wilt.' Goethe himself did this in untranslateable language.[24] Wordsworth did it in words known to all Englishmen, and which may be regarded as a forecast and religious vitalization of the latest and deepest scientific truth,-- 'For I have learned To look on nature; not as in the hour Of thoughtless youth; but hearing oftentimes The still, sad music of humanity, Nor harsh nor grating, though of ample power To chasten and subdue. _And I have felt A presence that disturbs me with the joy Of elevated thoughts; a sense sublime Of something far more deeply interfused, Whose dwelling is the light of setting suns, And the round ocean, and the living air, And the blue sky, and in the mind of man: A motion and a spirit, that impels All thinking things, all objects of all thought, And rolls through all things_.'[25] [1] Hume, _Natural History of Religion_.
