An Introduction to Psychology

It is not the intention of this introduction to psychology to discuss the scientific or philosophical conceptions of psychology, or even to make a survey of the investigations and their results. What this little book attempts is rather to introduce the reader to the principal thoughts underlying present-day experimental psychology, leaving out many facts and methods which would be necessary for a thorough study of the subject. To omit all mention of experimental methods and their results is at the present day impossible. Yet we only need to consider a comparatively small number of results of the first importance in order to comprehend the basal principles of the new psychology.
