ABSTRACT
Having sketched out the meanings in which our terms will be used, the best orientation for our study is probably to be secured by examining the literature. A great deal has been written on the subject of emotions in recent years, and to do justice to it all a large volume would be needed. If once printed this volume would be tedious reading. I have therefore no intention of doing more than giving a brief account and criticism of what a few have contributed towards solution of the problem, picking out those names which are associated with the more important hypotheses.
