Quotation of the Day…

… is from Chapter IX of Book IV, of the 1981 Liberty Fund edition of Adam Smith’s 1776 masterpiece, An Inquiry Into the Nature and Causes of the Wealth of Nations (footnote deleted):

Some speculative physicians seem to have imagined that the health of the human body could be preserved only by a certain precise regimen of diet and exercise, of which every, the smallest, violation necessarily occasioned some degree of disease or disorder proportioned to the degree of the violation. Experience, however, would seem to show that the human body frequently preserves, to all appearances at least, the most perfect state of health under a vast variety of different regimens; even under some which are generally believed to be very far from being perfectly wholesome. But the healthful state of the human body, it would seem, contains in itself some unknown principle of preservation, capable either of preventing or of correcting, in many respects, the bad effects even of a very faulty regimen. Mr. Quesnai, who was himself a physician, and a very speculative physician, seems to have entertained a notion of the same kind concerning the political body, and to have imagined that it would thrive and prosper only under a certain precise regimen, the exact regimen of perfect liberty and perfect justice. He seems not to have considered that, in the political body, the natural effort which every man is continually making to better his own condition is a principle of preservation capable of preventing and correcting, in many respects, the bad effects of a political œconomy, in some degree, both partial and oppressive. Such a political œconomy, though it no doubt retards more or less, is not always capable of stopping altogether the natural progress of a nation towards wealth and prosperity, and still less of making it go backwards. If a nation could not prosper without the enjoyment of perfect liberty and perfect justice, there is not in the world a nation which could ever have prospered. In the political body, however, the wisdom of nature has fortunately made ample provision for remedying many of the bad effects of the folly and injustice of man, in the same manner as it has done in the natural body for remedying those of his sloth and intemperance.

DBx: Yes. But of course it’s also true that just as excessive abuse of the body is fatal to the person, excessive abuse of the body politic is fatal to the people.


In 1776 on this date – March 9th – An Inquiry Into the Nature and Causes of the Wealth of Nations was first published. Nearly 250 years later, this work continues to dispense still-relevant and profound lessons to all who have the wisdom to heed the Great Scot.
