Ages of prolonged uncertainty, while they are compatible with the highest degree of saintliness in a few, are inimical to the prosaic every-day virtues of respectable citizens. There seems no use in thrift, when tomorrow all your savings may be dissipated; no advantage in honesty, when the man towards whom you practise it is pretty sure to swindle you; no point in steadfast adherence to the cause, when no cause is important or has a chance of stable victory; no argument in favour of truthfulness, when only supple tergiversation makes the preservation of life and fortune possible. The man whose virtue has no source except a purely terrestrial prudence will in such a world, become an adventurer if he has the courage, and, if not, will seek obscurity as a timid time-server.
