Book excerpt: Excerpt from The Evolution of Animal Intelligence The investigations of recent years have added so much to our knowledge of the activities of animals that any adequate account of the whole field of animal behavior would require several volumes. The present work is confined to certain topics which bear upon the evolution of animal intelligence, and our treatment of even this part of the subject has been of necessity fragmentary. It has been our aim to give a fairly clear conception of the activities upon which intelligence is based, to show how intelligence is related to these activities, and to sketch the general course of the evolution of intelligence in the animal kingdom. No effort has been made to deal with all the classes of animals in which intelligence is manifested, and some groups which were not essential to the development of our theme have received little attention. I wish to express my thanks to Prof. L. J. Cole and Prof. H. B. Torrey for their helpful criticisms of the manuscript of this book before it went to press. To Prof. L. T. Hobhouse, Prof. E. L. Thorndike and Dr. L. Witmer I am indebted for permission to reproduce the figures which are attributed to these writers in the text, and I am also indebted to the Macmillan Company for kindly allowing me to reproduce figures 15 and 16 from their publications. My greatest debt is to my wife for help and encouragement in many ways. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
