Note 670 — Chapter V

‘The uniform, constant, and uninterrupted effort of every man to better his condition, the principle from which public and national, as well as private, opulence is originally derived, is frequently powerful enough to maintain the natural progress of things towards improvement, in spite both of the extravagance of government and of the greatest errors of administration. Like the unknown principle of animal life, it frequently restores health and vigour to the constitution, in spite not only of the disease, but of the absurd prescriptions of the doctor.’ Wealth of Nations, book ii. chap. iii. p. 141. ‘The natural effort of every individual to better his own condition, when suffered to exert itself with freedom and security, is so powerful a principle, that it is alone, and without any assistance, not only capable of carrying on the society to wealth and prosperity, but of surmounting a hundred impertinent obstructions with which the folly of human laws too often encumbers its operations.’ Book iv. chap. v. p. 221.
