From, G. Murray, The value of Greece to the future of the world,
in R.W. Livingstone (ed.), The Legacy of Greece, Oxford University Press, 1921.
If the value of man's life on earth is to be measured in dollars and miles and horse-power, ancient Greece must count as a poverty-stricken and a minute territory; its engines and implements were nearer to the spear and bow of the savage than to our own telegraph and aeroplane. Even if we neglect merely material things and take as our standard the actual achievements of the race in conduct and in knowledge, the average clerk who goes to town daily, idly glancing at his morning newspaper, is probably a better behaved and infinitely better informed person than the average Athenian who sat spellbound at the tragedies of Aeschylus. It is only by the standard of the spirit, to which the thing achieved is little and the quality of mind that achieved it much, which cares less for the sum of knowledge attained than for the love of knowledge, less for much good policing than for one free act of heroism, that the great age of Greece can be judged as something extraordinary and unique in value.
By this standard, if it is a legitimate and reasonable one to apply, we shall be able to understand why classical Greek literature was the basis of education throughout all later antiquity; why its re-discovery, however fragmentary and however imperfectly understood, was able to intoxicate the keenest minds of Europe and constitute a kind of spiritual 'Re-birth', and how its further and further exploration may be still a task worth men's spending their lives upon and capable of giving mankind guidance as well as inspiration.
But is such a standard legitimate and reasonable? We shall gain nothing by unanalysed phrases. But I think surely it is merely the natural standard of any philosophical historian. Suppose it is argued that an average optician at the present day knows more optics than Roger Bacon, the inventor of spectacles; suppose it is argued that therefore he is, as far as optics go, a greater man, and that Roger Bacon has nothing to teach us; what is the answer? It is, I suppose, that Roger Bacon, receiving a certain amount of knowledge from his teachers, had that in him which turned it to unsuspected directions and made it immensely greater and more fruitful. The average optician has probably added a little to what he was taught, but not much, and has doubtless forgotten or confused a good deal. So that, if by studying Roger Bacon's life or his books we could get into touch with his mind and acquire some of that special moving and inspiring quality of his, it would help us far more than would the mere knowledge of the optician.
