"(From the preface) In the early summer of 1917, Professor Titchener began writing his Systematic Psychology--a book long projected. The book was to be his final word on the establishment of scientific psychology, coordinate with biology and physics; in a very concrete sense, it was to be a summing up of the reading, thinking, and experimental investigation in psychology which had occupied him during his entire professional life."--(PsycINFO Database Record (c) 2008 APA, all rights reserved).
