time. Especially was the time at my disposal cut down by the imperative necessity of working for a living. My work as contributor on the leading Anglo-American newspaper, the "New York Tribune," at which I have now been engaged for eight years, has caused very great interruption in my studies, since I engage in newspaper work proper only occasionally. Yet articles on important economic events in England and on the continent have formed so large a part of my contributions that I have been obliged to make myself familiar with practical details which lie outside the proper sphere of political economy.
This account of the course of my studies in political economy is simply to prove that my views, whatever one may think of them, and no matter how little they agree with the interested prejudices of the ruling classes, are the result of many years of conscientious research. At the entrance to science, however, the same requirement must be put as at the entrance to hell:
Qui si convien lasciare ogni sospetto
Ogni viltà convien che qui sia morta.
London, January, 1859.
