"The man who cannot wonder, who does not habitually wonder (and worship), were he President of innumerable Royal Societies, and carried the whole Mecanique Celeste and Hegel's Philosophy, and the epitome of all Laboratories and Observatories with their results, in his single head, is but a Pair of Spectacles behind which there is no Eye. Let those who have Eyes look through him, then he may be useful."
