Bio-psychology is that department of the science of mentation which studies organic structures and their environments in order to determine the relations which exist between these and the mentations which accompany them. It studies such structures and environments which nature provides and so far its method is that of observation, but it also artificially varies organic structures and environments, and to that extent its method is experimental. As experimental bio-psychology, it varies structure to determine function; and its scope includes three great sciences: 1. Biologic Psychology, which is that department of the science of mentation wherein our knowledge of mind is obtained by a scientific study of (A) organisms and their anatomical and molecular structures as exhibited by nature, and as varied by definite experimental conditions artificially produced; and by a study of (B) the cosmic environment of such organisms as exhibited in nature, and as varied by definite experimental conditions and also by a study of (C) the mentations of organisms as exhibited in nature in environments that have not been artificially disturbed, and as exhibited under the definite experimental conditions of organism and environment before mentioned. In other words, this science studies the individual organism as one factor in producing mentation of a definite
