War is an ugly thing, but not the ugliest of things. The decayed and
degraded state of moral and patriotic feeling which thinks that Nothing is
worth war is much worse. The person who has nothing for which he is willing
to fight, nothing which is more important than his own personal safety, is a
miserable creature and has no chance of being free unless made and kept so
by the exertions of better men than himself.
-- John Stuart Mill
