We have gone on constantly improving these blessings. But let any circumstances again arise which may be powerful enough to destroy, or even molest, the freedom of industry and the security of property, and we should work once more without certainty. The elements of prosperity would not be constant and uniform. We should work with the apprehension that some hurricane of tyranny, no matter from what power, would arise, which would sweep away accumulation. When that hurricane did not rise, we might have comparative abundance, like the people of Egypt during the inundation of the Nile. We then should have an inundation of tranquillity. But if the tranquillity were not present--if lawless violence stood in the place of justice and security--we should be like the people of Egypt when the Nile did not overflow. We should suffer the extremity of misery; and that possible extremity would produce an average misery, even if tranquillity did return, because security had not returned. We should, if this state of things long abided, by degrees go back to the condition of Colchester in the fourteenth century, and thence to the universal marsh of two thousand years ago. The place where London stands would be, as it once was, a wilderness for howling wolves. The few that produced would again produce laboriously and painfully, without skill and without division of labour, because without accumulation; and it would probably take another thousand years, if men again saw the absolute need of security, to re-create what security has accumulated for our present use.
