This chapter reviews several books and introduces their key contributions: 1. **Language, Truth and Logic by Alfred J. Ayer**: This book presents the views of new positivism, derived from scientific empiricism and a strict interpretation of logic. It emphasizes that sense-data are the primary elements of science, while metaphysics should be avoided. The author's enthusiasm reflects the growing influence of these theories in Britain, but the reviewer argues that this approach makes philosophy incomplete and uninspiring, as it overlooks the importance of intuitions of values and general principles. 2. **Grand-père de la Préhistoire by Dr. André Cheynier**: This book celebrates François-René-Benit Vatar de Jouannet, a pioneer in prehistoric archaeology. De Jouannet made significant discoveries, including the first described Neolithic site and the first classification of antiquity into stone, bronze, and iron ages. His work initiated scientific methods in archaeological investigation. 3. **Eclipses of the Sun by Prof. S. A. Mitchell**: This book, now in its fourth edition, provides a comprehensive account of solar eclipse observations. While it includes minor additions and a new chapter on recent eclipses, it lacks a general revision. The reviewer notes that recent observations at high-altitude stations have advanced understanding of the corona, but total eclipses remain crucial for many solar studies. 4. **Grundzüge der Vererbungslehre by Prof. Dr. Friedrich Alverdes**: This book offers a clear introduction to Mendelian inheritance, covering topics such as cell structure, fertilization, genotype and phenotype, and heredity in humans. It is well-explained but occasionally oversimplified, such as in its statement about the number of factors for eye and skin color in humans. 5. **The Psychology of Human Behavior by Prof. J. H. Griffiths**: This book is praised for its readability and structure, with added features like discussion questions and supplementary readings. It is considered one of the best elementary textbooks on psychology, making it highly valuable for both teaching and further study.This chapter reviews several books and introduces their key contributions: 1. **Language, Truth and Logic by Alfred J.
