"Ethical Know-How: Action, Wisdom, and Cognition" by Francisco J. Varela is a scholarly book that explores the complex relationships between science, experience, and ethical action. It sheds light on the challenges of modern neurobiology and cognitive science, particularly how unconscious, habitual actions are influenced by neurological and cognitive processes. Varela critiques traditional approaches that view cognition as abstract representation and rule-following, and instead proposes a concept of Enaction. This concept emphasizes the importance of embodied experience and sensory-motor skills in everyday life. By integrating ideas from phenomenology as well as the wisdom traditions of Confucianism and Buddhism, Varela develops a practice-based ethics that understands ethical action as a process of being, rather than a rigid set of rules. The book thus offers a profound reflection on the connection between cognition, ethics, and human action.
