Political Thought in England from Herbert Spencer to To-day, by Ernest Barker. (Home University Library.) New York: Henry Holt and Co. 50 cents net. When peace has at last been signed, and the world becomes in some sort a reasonable place, Englishmen will be compelled to turn to the reconstruction of their political life. What is the mental attitude in which they will approach that task? Whence will be drawn its deepest inspiration? To these questions Mr. Barker's book is in some sort an answer. It is a valuable book.
