This book tells what we know of man, how he first lived, how he worked with other men, what kinds of houses he built, what tools he made, and how he formed a government under which to live. So we learn of the activities of men in the past and what they have passed on to us. In this way we may become acquainted with the different stages in the process which we call civilization. The present trend of specialization in study and research has brought about widely differentiated courses of study in schools and a large number of books devoted to special subjects. Each course of study and each book must necessarily represent but a fragment of the subject. This method of intensified study is to be commended; indeed, it is essential to the development of scientific truth. Those persons who can read only a limited number of books and those students who can take only a limited number of courses of study need books which present a connected survey of the movement of social progress as a whole, and which blaze a trail through the accumulation of learning, and give an adequate perspective of human achievement. It is hoped, then, that this book will form the basis of a course of reading or study that will give the picture in small compass of this most fascinating subject. If it serves its purpose well, it will be the introduction to more special study in particular fields or periods. That the story of this book may be always related more closely with the knowledge and experience of the individual reader, questions and problems have been added at the conclusion of each chapter, which may be used as subjects for discussion or topics for themes. For those who wish to pursue some particular phase of the subject a brief list of books has been selected which may profitably be read more intensively.
