I have spoken hitherto of the possibility that democracy may be a self-limiting disease, like measles. It is, perhaps, something more: it is self-devouring. One cannot observe it objectively without being impressed by its curious distrust of itself-its apparently ineradicable tendency to abandon its whole philosophy at the first sign of strain. I need not point to what happens invariably in democratic states when the national safety is menaced. All the great tribunes of democracy, on such occasions, convert themselves, by a process as simple as taking a deep breath, into despots of an almost fabulous ferocity.
