Remarks on François Jacob’s Concept of Integron

In this article, the concept of integron as it appears in François Jacob’s book The Logic of Life is discussed. It begins by locating the concept within the overall structure of Jacob’s book. The book is conceived as a history of heredity, with the central historical chapters framed by an epistemological discussion of the notions of program in the introductory chapter and of integron in the concluding chapter. A detailed analysis of the concept of integron follows, including that of reproduction on which it relies. It is then compared with the concept of hypercycle as developed around the same time by Manfred Eigen and Peter Schuster. The article concludes on a note on name-coining in the sciences with a focus on Jacob’s own practice.
