John Barry calls our attention to the views of Thomas Huxley who gave the keynote address at the founding of the Johns Hopkins University:
(p. 13) A brilliant scientist, later president of the Royal Society, he advised investigators, “Sit down before a fact as a little child, be prepared to give up every preconceived notion. Follow humbly wherever and to whatever abysses nature leads, or you shall learn nothing.” He also believed that learning had purpose, stating, “The great end of life is not knowledge but action.”

(Note: from the context in Barry, I am not certain whether the Huxley quotes are from the keynote address, or from elsewhere in Huxley’s writings.)
