Rh may be mentioned the evolutionary hypothesis, and what may be called, in contradistinction to the intellectual analytical psychology of Mill's time, the scientific psychology of the present. The most influential of all Mill's writings has been "The Principles of Political Economy," published in 1848. In writing this treatise, Mill had two purposes in view. In the first place, he wished to bring together the many improvements which had been made in the principles of the subject since the appearance of "The Wealth of Nations" in 1776 and, following the example of Adam Smith, to illustrate their practical applications. Here he was conspicuously successful. Many writers in recent years have set themselves the same task with no such measure of accomplishment. In the second place, he wished to relate economic principles and phenomena to his own social ideals and social philosophy. The character of these social ideals and the nature of his social philosophy are abundantly set forth in the "Autobiography," where particular attention is given to the influence upon his mind of his wife and of Auguste Comte, the father of the science of sociology. It can hardly be said that Mill was fully successful in this effort. The purely economic part of the treatise and the social philosophy are not fused together and at times are positively contradictory. Nevertheless, the treatise gained in human interest from the effort thus made, and at all events the way was indicated toward a broader treatment of social and economic questions than had been customary among economists since the time of Adam Smith.

An ardent desire for social as well as individual progress is conspicuous both in the analysis of the growth of his own mind and in what is said about his own writings. Detailed consideration of the various reforms which he advocated in his writings is impossible within the narrow limits of a single lecture. In a general way it may be noted that Mill expected greater results from the removal of obstructions to freedom of thought and action and from education than in fact have been realized. It is now more clearly evident that the removal of
