The article discusses the ongoing debate about the nature of life and the organizing principles that govern biological systems. It highlights the historical attempts by philosophers and scientists to define these principles, such as "final cause," "the élan vitale," and "entelechy." While modern science often ignores these concepts due to the lack of measurable evidence, the author argues that they must be acknowledged as part of the biological process. The true scientist, according to the article, remains humble and open to new discoveries, recognizing that our understanding of life's laws is still incomplete. The article also suggests that mind plays a crucial role in biological functions, similar to the self-regulatory forces in growth and development. The second part of the article reviews several scientific publications. The first is the "Handbook of Biological Data," a comprehensive compilation of biological information, organized into ten sections and including numerous tables. While it is a valuable resource, it is considered less detailed than other specialized handbooks. The second is "Essentials of Histology," a concise textbook for beginners in the field. It provides a foundational understanding of histology but lacks recent advancements in the field. The third is "Blakiston's New Gould Medical Dictionary," a comprehensive medical dictionary that covers a wide range of medical and scientific terms. Each of these publications contributes to the broader understanding of biology and medicine, offering essential resources for researchers and students.The article discusses the ongoing debate about the nature of life and the organizing principles that govern biological systems.
