PREFACE

This work is not a text-book of theoretical biology; it is a systematic presentment of those biological topics which bear upon the true philosophy of nature. The book is written in a decidedly subjective manner, and it seems to me that this is just what “Gifford Lectures” ought to be. They ought never to lose, or even try to lose, their decidedly personal character.
