ABSTRACT
OUR emotions are the most obscure part of our lives, and, as might be expected, the theory of emotion is the most backward part of psychology. This is the reason for postponing detailed consideration of it to so late a stage, not any minor or secondary importance of the emotional aspect of experience and be-haviour. On the contrary, the history of a life is a history of interests rather than of ideas; and, if we could follow it closely enough, we should find that an understanding of the emotional situation was at every turn the key to the rest. Moreover, it is on his emotional organization that a man's character essentially depends.
