PETTY'S ECONOMIC WRITINGS.


Those who hitherto have discussed Petty as a writer on economic subjects have confined themselves pretty closely to summary and criticism of his theories. The writings are now before the reader, who may summarize and criticize as his purpose demands or his taste suggests. It remains for the editor to account, if he can, for the writings as they are.

A man of force makes his way in this world through no impalpable ether. The medium through which he moves is dense, and deflects his course now this way, now that, according to the form and temper of the surface that he presents to the buffeting of affairs. His intellectual orbit cannot be precisely calculated even with a knowledge of the initial direction and velocity of his mind and of the attraction which draws its flight towards a fixed centre. But every man not wholly erratic is at once impelled by his circumstances and restrained by his training. Postulate these, and you may discover in his actual course some trace of the mean orbit which calculation would predict.

The inspiration of Petty's writings is not far to seek. Written before the days of formal treatises on political economy, they are neither the systematized abstractions of a metaphysician condescending to every-day affairs, nor the less systematic but no less abstract arguments of a man of affairs with an undisciplined bent toward speculative thinking.

In his earlier years, to be sure, he had been a man of the library as well as of the laboratory; but experience taught him to value the education of life above that of books, and in his writings he uses authorities seldom and not well. To Aubrey he declared that he had read little since his twenty-fifth year,
