FR0M the fall of I 934 until the summer of 1940 I had the
privilege of occupying the chair of International Economic
Kelations at the Graduate Institute of International
Studies in Geneva, Switzerland. In the serene atmosphere
of this seat of learning, which two eminent scholars, Paul
Mantoux and William E. Kappard, had organized and continued
to direct, I set about executing an old plan of mine,
to write a comprehensive treatise on economics. The book-
Nationalokonomie, Theorie des Handelns zmd Wirtschaftens
-was published in Geneva in the gIoomy days of May, 19.10.
The present volume is not a translation of this earlier book.
Although the general structure has been little changed, all
parts have been rewritten.
To my friend Henry Hazlitt I wish to off er my very special
thanks for his kindness in reading the manuscript and giving
me most valuable suggestions about it. I must also gratefully
acknou~ledgem y obligations to Mr. Arthur Coddard for linguistic
and stylistic advice. I am furthcrmore deeply indebted
to Mr. Eugene A. Davidson, Editor of the Yale University
Press, and to Mr. Leonard E. Read, President of the Foundation
for Economic Education, for their kind encouragcment
I need hardly add that none of these gentlemen is either directly
or indirectly responsible for any opinions contained in
this work. Ludwig Von Mises
