Excerpt from An Introduction to Psychology The student taking up different text-books of psychology will find various definitions of the subject, and ne that we can offer will meet with universal acceptance among psychologists. To those who pin their faith to definitions this may appear to be a serious matter, and it would certainly be an advantage if we could state in precise and generally accepted terms the exact nature of the facts with which our science is concerned. These differences of opinion, however, do t persist because psychologists are more muddle-headed than other people. There are very good reasons for the divergent views. Some of these reasons are in a sense extraneous, arising from the historical relations of the science to other branches of thought as, for example, ethics and metaphysics.
