The golden mean is an uninteresting doctrine, and I can remember when I was young rejecting it with scorn and indignation, since in those days it was heroic extremes that I admired. Truth, however, is not always interesting, and many things are believed because they are interesting; although, in fact, there is little other evidence in their favour. The golden mean is a case in point: it may be an uninteresting doctrine, but in a very great many matters it is a true one.
