rendered an important service to philosophy in bringing together and publishing these minor writings of so eminent a philosopher as Lotze, and one so thoroughly in touch with the spirit of modern thought. If it is true that we cannot thoroughly understand any philosophical or theological system until we see it in process of becoming, these volumes of chronologically arranged papers give us assistance in understanding the intellectual development of one of the greatest thinkers of the century.
The editor seems to have brought to this work the patience and devotion of a disciple, and has spared no effort to present to his readers down to the minutest detail what Lotze wrote. An extremely useful feature of the work, and one which must have involved much labor, is an index of nearly four hundred passages, which contains not only references to the different Schriften, but oftentimes numerous quotations from them. Professor Peipers's extreme thoroughness and care in carrying out this admirable piece of work cannot be too highly commended.

The introduction, in which the translator presents Kant's philosophical teaching in its unity, cannot but be helpful to those who are already familiar with Kant's metaphysical teaching, as well as to those who begin the study of Kant with his Essays on Politics.
In the early part of the introduction, the development of Kant's philosophical thinking through the scientific, the speculative, and the practical stages is well worked out. Kant "passes, as by natural and necessary continuity, from science and theoretical criticisms into the moral world as the living realm of practice." Considerable prominence is given to the influence of Kant's early scientific investigations on his subsequent speculation. Kant's thinking in each period centred around the teaching of a great man. During the first period, Kant, in the character of a disciple, followed Newton. Deeply impressed with the universality and the necessity of the principles of science, mathematical and physical, Kant found Hume's metaphysic insufficient to explain the possibility of a science of nature. The disciple of Newton became the opponent of Hume. The champion of Reason in the tournament with
