IX. PHILOSOPHICAL PERIODICALS. PHILOSOPHICAL REVIEW. Vol. v., No. 4. H. Calderwood. ' The Relation of Intuitionisin to the Doctrine of Self-Realisation.' [Current intuitionism as a theory of our knowledge of the moral law, which includes self-realisation as an end ; Sidgwick's criticism. Self-realisation as ethics of the end : its monistic or idealistic form (Green) ; regarded as depen- dent upon exercise of human intelligence (Green, Dewey, Muirhead, etc.). Self-realisation implies knowledge of the end ; its weakness lies in the fact that it offers an incomplete theory of this, and so gets into difficulties as to the end itself.] J. H. Hyslop. ' The Fourth Dimension of Space.' [There are ' logical principles, which not only vitiate the argument for the existence, or even possibility, of this dimension, but make the talk about it mere child's-play '. ' The logical terms of the problem take us wholly beyond the limits of geometry and mathematics.'] A. Llano. ' Morality the Last of Dogmas.' [' In the course of time, all moral feel- ings . . . will disappear from the human mind and cease to have any influence upon the further development of the race.' In other words, the evolution (or dissolution) ' of morality is from duty towards right, the former diminishing as the latter increases '. Psychological reasons for this view ; indications of its correctness in present religious and political tolerance.] Discussions. J. E. Russell. ' Self -consciousness, social consciousness and nature.' [Criticism of Royce's proofs that ' there is other human experience than my own,' and that ' nature is other reality than human experience '.] R. B. Johnson. ' Mr. Balfour and Transcen- dental Idealism.' [Criticism of Daniels' paper, Vol. v., No. 1.] M. Washburn. ' The Intensive Statement of Particular and Negative Pro- positions.' [Jevons' equivalent proposition in intension for a universal negative may in some cases be equivalent to a particular affirmative instead. It is useless to try and find an intensive equivalent for the par- ticular proposition.] Reviews of Books. Summaries of Articles. Notices of New Books. Notes. Vol. v., No. 5. O. Pfleiderer. ' Is Morality without Religion Possible and Desirable ? ' [Consideration of arguments brought by moralists against a religious sanction for ethics, and by representatives of religion against a non-religious ethics. Those who demand ' a truly ideal morality and a truly ethical community must labour, not for a morality outside of the Church, but for a reformation within the Church '.] J. C. Murray. ' The Idealism of Spinoza.' [A careful analysis of the doctrine of the Ethics, which the writer takes to be ' that the universe, under all its varied phases, is essentially an evolution of intelligence '.] EL GrifFing. ' On the Relations of Psychology to Other Sciences.' [Examines the re- lations of psychology, from the o posteriori and a priori standpoints, to other sciences, especially physics and physiology. Concludes, not very convincingly, that problems and methods are often the same for all.] S. E. Mezes. ' The Cause and Function of Conscience.' [The psycho- logical cause of conscience ( = every approval and disapproval) is volun- tary action, apprehended as such. Hence the varietj T and variations of consciences. With the appearance of voluntary action comes the jeopardising of the self-sacrificing race-preserving instincts : it is the function of conscience to act as counter-check upon apprehended volun-
