Principles of Gestalt Psychology

When I first conceived the plan of writing this book I guessed, though I did not know, how much effort it would cost to carry it out, and what demands it would put on a potential reader. And I doubted, not rhetorically but very honestly and sincerely, whether such labour on the part of the author and the reader was justified. I was not so much troubled by the idea of writing another book on psychology in addition to the many books which have appeared during the last ten years, as by the idea of writing a book on psychology. Writing a book for publication is a social act. Is one justified in demanding co-operation of society for such an enterprise? What good can society, or a small fraction of it, at best derive from it? I tried to give an answer to this question, and when now, after having completed the book, I return to this first chapter, I find that the answer which then gave me sufficient courage to start on my long journey, has stayed with me to the end. I believed I had found a reason why a book on psychology might do some good. Psychology has split up into so many branches and schools, either ignoring or fighting each other, that even an outsider may have the impression surely strengthened by the publications. "Psychologies of 1925" and "Psychologies of 1930" that the plural "psychologies" should be substituted for the singular.
