“Le hasard pur, absolument libre et aveugle, est la véritable racine du merveilleux édifice de l'évolution.”

Jacques Monod

Pure chance, absolutely free but blind, is at the very root of the stupendous edifice of evolution.

“L’ancienne alliance est rompue ; l’homme sait enfin qu’il est seul dans l’immensité indifférente de l’Univers d’où il a émergé par hasard. Non plus que son destin, son devoir n’est écrit nulle part. À lui de choisir entre le Royaume et les ténèbres.”

Jacques Monod: Citations en anglais

“What I consider completely sterile is the attitude, for instance, of Bertalanffy who is going around and jumping around for years saying that all the analytical science and molecular biology doesn’t really get to interesting results; let’s talk in terms of general systems theory … there cannot be anything such as general systems theory, it’s impossible. Or, if it existed, it would be meaningless.”

Monod (1974) On the Molecular Theory of Evolution

“One day, almost exactly 25 years ago - it was at the beginning of the bleak winter of 1940 - I entered André Lwoff’s office at the Pasteur Institute. I wanted to discuss with him some of the rather surprising observations I had recently made.
I was working then at the old Sorbonne, in an ancient laboratory that opened on a gallery full of stuffed monkeys. Demobilized in August in the Free Zone after the disaster of 1940, I had succeeded in locating my family living in the Northern Zone and had resumed my work with desperate eagerness. I interrupted work from time to time only to help circulate the first clandestine tracts. I wanted to complete as quickly as possible my doctoral dissertation, which, under the strongly biometric influence of Georges Teissier, I had devoted to the study of the kinetics of bacterial growth. Having determined the constants of growth in the presence of different carbohydrates, it occurred to me that it would be interesting to determine the same constants in paired mixtures of carbohydrates From the first experiment on, I noticed that, whereas the growth was kinetically normal in the presence of certain mixtures (that is, it exhibited a single exponential phase), two complete growth cycles could be observed in other carbohydrate mixtures, these cycles consisting of two exponential phases separated by a-complete cessation of growth.”

Introduction
From enzymatic adaptation to allosteric transitions (1965)

“The ancient covenant is in pieces; man knows at last that he is alone in the universe's unfeeling immensity, out of which he emerged only by chance. His destiny is nowhere spelled out, nor is his duty. The kingdom above or the darkness below: it is for him to choose.”
