The author attacks recent as well as traditional philosophic speculation and attempts to formulate his own resolution to all the outstanding problems in philosophy. But the elaboration of his "psycho-physiological monism" results in involving the author in most of the difficulties he claimed to avoid.--R. T. L.

A clear and highly readable account of the main currents of existentialist thought, together with a briefer discussion of the relation of these ideas to the recurrent themes of Indian philosophy.--R. T. L.

The author claims to be aiming at the conception of a "finite metaphysics," which is described as a metaphysics which draws heavily upon researches in symbolic logic and the empirical sciences. The result is uneven, and at times wearisome. Though several sections are interesting and valuable in their own right, in this "open system of finite ontology" one finds more openness than system.--R. T. L.

The author conducts an investigation into the biological foundations of mental phenomena, together with a short history of reason itself, in the course of which he discovers that "the formation of abstract concepts did only begin at the time of Plato."--R. T. L.

A shallow book in which the author gives us his opinions on topics ranging from religion to the policy of grading students.--R. T. L.

In this refreshingly different study of Whitehead's thought, Miss Wyman attempts to elicit the aesthetic relevance of Whitehead's categories by means of comparisons and contrasts with such men as Goethe, Emerson, Whitman, and particularly, Wordsworth. Although not a technically rigorous discussion, Miss Wyman's book is useful and instructive.--R. T. L.

In this Aquinas lecture the author defends the idea of wisdom as a valid and valuable topic for philosophic discussion. Collins devotes most of his energies to explaining the largely neglected Cartesian view of wisdom. He concludes that by the method of "metaphysical ingression" we can give the subject of wisdom its proper close connection with the whole of metaphysics.--R. T. L.

A portion of the works of Lachelier give a comprehensive view of the kind of neo-Kantian idealism he espouses. In his introduction Mr. Ballard presents a summary of Lachelier's philosophy, expanding somewhat on the more obscure sections of his work.--R. T. L.
