“ More than this man never can do. Always beyond the farthest vision of his telescope and microscope will lie the unknowable, growing smaller, perhaps, but seeming larger as it gives up some of its secret places for the inhabiting of the dwellers in the known. And this is the significant thing, that, as our knowledge grows, our sense of what lies beyond that knowledge finds an increasing number of things that may excite wonder. Every new scientific discovery, at least in certain departments of science, simply acts as an index finger pointing the way to related phenomena not yet understood. ”
