Mathematical Philosophy 



A Study of Fate and Freedom 



By CASSIUS J. KEYSER, Ph. D., LL.D. 



Adrain Professor of Mathematics, 



Columbia University 



These "lectures for educated laymen" aim at 

 democratizing science and scientific criticism. They 

 show that the greatest of mathematical ideas — the 

 pillar-concepts of the science — belong no more to 

 mathematics than to all science and to rational 

 thought in general. The great pillar-concepts are 

 explained in the simplest terms. The reader need 

 not be a mathematical specialist. The lectures are 

 not addressed primarily to mathematical techni- 

 cians. They are designed for students and teach- 

 ers whether of mathematics or philosophy or en- 

 gineering or psychology or logic or education or 

 sociology or art or natural science and for all 

 other students, thinkers and critics who own alle- 

 giance to the laivs of thought and who desire to 

 gain a fair understanding of the nature, the spirit, 

 the standards and the bearings of the science 

 which Plato called divine.
