Jacques Monod, Chance and Necessity – PhilPapers
He says this “random” message seems to be composed haphazardly from a random origin and he ends the chapter poetically: He states that the source of information for the antibodies associative structure is not the antigen itself but is instead the result of many random recombinations of part of the antibody gene. The sequence of nucleotides in DNA defines the sequence of amino acids which in turn defines the folding of proteins which in turn defines an organism; “One must regard the total organism as the ultimate epigenetic expression of the genetic message itself” Monod, Monod again references his own work as he talks about the lactose system consisting of three proteins in Escherica coli.
To them, a being made sense and was understandable only through the purpose animating the being and so, if mysterious objects, such as rocks, rivers, rain, and stars, exist it must also be for a purpose essentially there are no inanimate objects to them. Upon dissociation each protomer can assume a relaxed state and this concerted response of each protomer accounts for the nonlinearity of enzyme activity: Chance and Necessity by Jacques Monod.
Dec 10, John Jr. The definition of life he puts forth in this book — those systems possessing teleonomy, autonomous mor Jacques Monod won the Nobel Prize in for his work elucidating the molecular mechanisms of DNA replication.
Monod next points out that our ancestors had a history of animating objects by giving spirits to them so as to bridge the apparent gap between the living and non-living. This differs from the usual viewpoint, which sees the genome as fundamental and proteins as secondary.
While some might choose to build a world-view on this, you don’t have to subscribe to any of it; by Monod’s own cognisance, you can make your own “free choice”.

See other reviews, especially this one: Robert Wilensky – – Behavioral and Brain Sciences 13 4: Monod’s interest in the lac operon originated from his doctoral dissertation, for which he studied the growth of bacteria in culture media containing two sugars.
An ethic which bases moral responsibility upon the very freedom of that axiomatic choice. Monod mentions oligomeric globular proteins again and how they appear in aggregates containing geometrically equivalent protomer subunits associated into a non-covalent steric complex. The antibody that is able to bind to the antigen is multiplied. Many have enumerated the gaps in the science of the day on which he based his arguments, although most of the criticism I’ve seen on this point falls under the “dark corners of our knowledge” rubric, the type of pedantic denialism founded on a false understanding of what science tells us and how it does so, and a lack of appreciation for the true depth and breadth of evidence supporting the theory of the spontaneous biogenesis and evolution of life on this planet.
Jun 17, Bob Nichols rated it really liked it. He shows how these enzymes are to all intents and purposes wonderfully ingenious machines, which give every appearance of having been designed to serve highly specific purposes; but, just when you think he’s contradicted himself, he goes on to demonstrate that their structure reveals they can only be the product of blind chance.
The author now concentrates on what he views as one of the unique properties of higher-level organisms, namely that of simulating experience subjectively so as to anticipate results and prepare action.
Sign in to use this feature. He contends that the persistence of those concepts is responsible for the intensifying schizophrenia of a world that accepts, and lives by, the fruits of science while refusing to face its moral implications.
Molecular biologist and Nobel-winner Monod takes a look at the philosophical significance of evolution and the genetic code.
jacqued This leads him into some very value-laden pronouncements about how society ought to be organized. This is followed by a scathing analysis of various kinds of vitalist obscurantism including modern “scientific” vitalisms which go by other names and of animist approaches to evolution from dialectical materialism to Teilhard de Chardin.
Vecchiotto e si sente.
It is interesting that nowhere in this book does Monod talk about human motivation and our emotional make up. The last general property Monod offers up as distinguishing living organisms is reproductive invariance which is the ability of a living being to reproduce and transmit the information corresponding to their own highly ordered structure. Monod hypothesizes that language was not merely the product but one of the driving forces for the evolution of our central nervous system.
Toward the end of the preface Monod offers apology for any overly neceesity or technical sections. It is znd idea that owes its force to its logical coherence alone. Rudolf Steiner – – R. The dialectical process begins with life, seeking to live and to live well.
Monod writes that an enzymatic reaction can be seen in two steps: Vitalisms such as Bergson’s creative evolution and animisms such as Marxism project teleology onto nature, reading into it a guiding principle governed by ends like humans are governed by ends.
The universe was not pregnant with life nor the biosphere with man. He offers the selective theory as being consistent with the postulate of objectivity and allowing for epistemological nscessity. Allosteric interactions are mediated by discrete shifts in the proteins structure and this allows certain proteins to assume different conformational states.
The author says that this animist belief is due to a projection of man’s awareness of his own teleonomic functioning onto inanimate nature. This page was last edited on 13 Novemberat He talks about the extraordinary specificity of action that enzymes display as exemplified by their ability to not only recognize a jacquex geometric isomer but an optical isomer as well.
