MIND AND THE WORLD-ORDER, C. I. Lewis. Building upon the work of Peirce, James, and 

 Dewey, Professor Lewis outlines a theory of knowledge in terms of "conceptual pragmatism." 

 Dividing truth into abstract mathematical certainty and empirical truth, the author' demon- 

 strates that the traditional understanding of the a priori must be abandoned. Detailed 

 analyses of philosophy, metaphysics, method, the "given" in experience, knowledge of objects, 

 nature of the a priori, experience and order, and many others. Appendices, xiv + 446pp.

SCEPTICISM AND ANIMAL FAITH, G. Santayana. To eliminate difficulties in the traditional 

 theory of knowledge, Santayana distinguishes between the independent existence of objects 

 and the essence our mind attributes to them. Scepticism is thereby established as a form of 

 belief, and animal faith is shown to be a necessary condition of knowledge. Belief, classical 

 idealism, intuition, memory, symbols, literary psychology, and much more, discussed with 

 unusual clarity and depth. Index, xii -I- 314pp. 53/8 x 8.

LANGUAGE AND MYTH, E. Cassirer. Analyzing the non-rational thought processes which go to 

 make up culture, Cassirer demonstrates that beneath both language and myth there lies a 

 dominant unconscious "grammar" of experience whose categories and canons are not those 

 of logical thought. His analyses of seemingly diverse phenomena such as Indian metaphysics, 

 the Melanesian "mana," the Naturphilosophie of Schelling, modern poetry, etc., are profound 

 without being pedantic. Introduction and translation by Susanne Langer. Index, x + 103pp.

SUBSTANCE AND FUNCTION, EINSTEIN'S THEORY OF RELATIVITY, E. Cassirer. In this double- 

 volume, Cassirer develops a philosophy of the exact sciences that is historically sound, philo- 

 sophically mature, and scientifically impeccable. Such topics as the concept of number, space 

 and geometry, non-Euclidean geometry, traditional logic and scientific method, mechanism and 

 motion, energy, relational concepts, degrees of objectivity, the ego, Einstein's relativity, and 

 many others are treated in detail. Authorized translation by W. 0. and M. C. Swabey. xii -f

 analysis of physics, prerelativity physics, causality, scientific inference, Weyl's theory, tensors, 

 invariants and physical interpretations, periodicity, and much more is treated with Russell's 

 usual brilliance. "Masterly piece of clear thinking and clear writing," NATION AND ATHENAE- 

 UM. "Most thorough treatment of the subject," THE NATION. Introduction. Index. 8 figures,

CONCEPTUAL THINKING (A LOGICAL INQUIRY), S. Korner. Discusses origin, use of general 

 concepts on which language is based, and the light they shed on basic philosophical ques- 

 tions. Rigorously examines how different concepts are related; how they are linked to experi- 

 ence; problems of the field of contact between exact logical, mathematical, and scientific 

 concepts, and the inexactness of everyday experience (studied at length). This work elab- 

 orates many new approaches to the traditional problems of philosophy — epistemology, value 

 theories, metaphysics, aesthetics, morality. "Rare originality . . . brings a new rigour into 

 philosophical argument," Philosophical Quarterly. New corrected second edition. Index, vii

INTRODUCTION TO SYMBOLIC LOGIC, S. Langer. No special knowledge of math required — 

 probably the clearest book ever written on symbolic logic, suitable for the layman, general 

 scientist, and philosopher. You start with simple symbols and advance to a knowledge of 

 the Boole-Schroeder and Russell-Whitehead systems. Forms, logical structure, classes, the 

 calculus of propositions, logic of the syllogism, etc., are all covered. "One of the clearest 

 and simplest introductions," MATHEMATICS GAZETTE. Second enlarged, revised edition. 368pp.

 the Self and the World; logic and common sense, and other philosophic concepts. An aid to 

 clarity of thought as well as the first full-length development of Logical Positivism in English.

ESSAYS IN EXPERIMENTAL LOGIC, J. Dewey. Based upon the theory that knowledge implies a 

 judgment which in turn implies an inquiry, these papers consider the inquiry stage in terms 

 of: the relationship of thought and subject matter, antecedents of thought, data and mean- 

 ings. 3 papers examine Bertrand Russell's thought, while 2 others discuss pragmatism and a 

 final essay presents a new theory of the logic of values. Index, viii + 444pp. 53/8 x 8.

TRAGIC SENSE OF LIFE, M. de Unamuno. The acknowledged masterpiece of one of Spain's 

 most influential thinkers. Between the despair at the inevitable death of man and all his 

 works and the desire for something better, Unamuno finds that "saving incertitude" that 

 alone can console us. This dynamic appraisal of man's faith in God and in himself has been 

 called "a masterpiece" by the ENCYCLOPAEDIA BRITANNICA. xxx + 332pp. 53/8 x 8.
