A Textbook in Psychology, written by Johann Friedrich Herbart in 1891, is a comprehensive guide to the study of psychology. Herbart attempts to establish psychology as a science based on experience, metaphysics, and mathematics. The book is divided into three sections, each of which explores a different aspect of psychology. The first section discusses the nature of psychology and its relationship to other sciences, such as physics and biology. The second section delves into the study of mental processes, including perception, memory, and attention. The third section focuses on the application of psychology to education, including the development of moral character and the role of the teacher in the learning process. Throughout the book, Herbart emphasizes the importance of empirical observation and the use of mathematical models to understand psychological phenomena. A Textbook in Psychology is a seminal work in the history of psychology and remains a valuable resource for students and scholars in the field.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
