Thus we should be wrong if we had said hastily that there is no humility typical
of our time. The truth is that there is a real humility typical of our time; but
it so happens that it is practically a more poisonous humility than the wildest
prostrations of the ascetic. The old humility was a spur that prevented a man
from stopping; not a nail in his boot that prevented him from going on. For the
old humility made a man doubtful about his efforts, which might make him work
harder. But the new humility makes a man doubtful about his aims, which will
make him stop working altogether.
