The Tree of Knowledge: The Biological Roots of Human Understanding, by Humberto R. Maturana and Francisco J. Varela, is a groundbreaking book that seeks to revolutionize the understanding of the biological roots of human cognition. First published in 1987, it has since been translated into multiple languages and is now in its revised edition. The book presents a novel approach to the philosophy of science, emphasizing the connection between biology and cognition. Maturana and Varela argue that cognition is not a representation of the external world, but rather an ongoing process of creating a world through living. The book explores various aspects of biology, including reproduction, life cycles, and the organization of cells, and uses these to develop a deeper understanding of cognition and knowledge. The authors also discuss the concept of autopoiesis, which is central to their theory of living systems. The book is not straightforward, but it offers a rich and complex exploration of the nature of knowledge and the processes of evolution. It is recommended for academics in science education, philosophy of science, and the life sciences, as it provides a stimulating and challenging read. The book is a valuable contribution to the field, offering a unique perspective on the nature of knowledge and the processes of evolution.The Tree of Knowledge: The Biological Roots of Human Understanding, by Humberto R.
