The Philosophy of Immunology (Elements in the Philosophy of Biology) by Thomas Pradeu delves into the profound implications of immunology within contemporary biological and medical frameworks, offering a fresh perspective through its unique contributions to philosophy. Central to this work is the exploration of biological individuality—what constitutes a distinct biological entity, what factors define it as unique, how its boundaries are established, and mechanisms that ensure its continuity over time. Additionally, Pradeu addresses fundamental philosophical questions such as defining life itself, delineating bodily systems, and understanding the interactions between mind and body. Through this Element, readers gain insight into how immunology can illuminate these critical issues, making it a valuable resource for philosophers, biologists, and medical professionals alike.
