In the “Principles of Political Economy,” these opinions were promulgated, less clearly and fully in the first edition, rather more so in the second, and quite unequivocally in the third. The difference arose partly from the change of times, the first edition having been written and sent to press before the French Revolution of 1848, after which the public mind became more open to the reception of novelties in opinion, and doctrines appeared moderate which would have been thought very startling a short time before. In the first edition the difficulties of Socialism were stated so strongly, that the tone was on the whole that of opposition to it. In the year or two which followed, much time was given to the study of the best Socialistic writers on the Continent, and to meditation and discussion on the whole range of topics involved in the controversy: and the result was that most of what had been written on the subject in the first edition was cancelled, and replaced by arguments and reflections which represent a more advanced opinion.
Note from KBJ: These were the days in which new editions had more than cosmetic changes.
