It is the same story everywhere. Do we want the best book on _Rhetoric_ or _Politics_? Aristotle may supply it, mainly because he took the trouble to classify his instances and show the reason why things not only are of such a kind, but must inevitably be so. A course of Aristotelian study might profitably be prescribed to every person who thinks of talking in public; he would at least learn how to respect himself and his audience, however ignorant and powerful it may be; he would tend to use words in an exact sense instead of indulging in the wild vagueness of speech which is so common and so dangerous. This dry-as-dust philosopher who cut up animals and plants and wrote about public speeches and constitutions found time to give the world a book on Poetry. Modern scientists sometimes deny their belief in the existence of such a thing as poetry, or scoff at its value; no poetic treatise has yet appeared from them, for it seems difficult for modern science to keep alive in its devotees the weakest glimmerings of a sense of beauty. Herein their great founder and father shows himself to be more humane than his so-called progressive children. His _Poetics_ was the foundation of literary criticism and shows no sign of being superseded. Turning his eyes upwards, he gave the world a series of notes on what he saw there. Not possessing a telescope, he could but do his best with the methods available. Let us not jeer at his results; rather let us remember that this same astronomer found time to observe the heavens in addition to revolutionising thought in the brief compass of sixty-two years. For the miracle of miracles is this man's universality of outlook. It makes us ashamed of our own pretentiousness and swollen-headed pride when we reflect what this great architectonic genius has performed. Just as our bodies have decreased in size with the progress of history, so our intelligences seem to have narrowed themselves since Aristotle's day. Great as our modern scientists are, there is not one of them who would be capable of writing an acknowledged masterpiece on Ethics, Politics, Rhetoric, Poetry, Metaphysics as well as on his own subject.
