Jacques Monod and Chance and Necessity.

Nonetheless, this is an exceptional work It has jaqcues a good long time since I read this book. The author points to what he sees as the acceptance of objective science in practice but not in spirit.

Dismissing as “animist” not only Plato, Hegel, Bergson and Teilhard de Chardin but Spencer and Marx as well, he calls for a new ethic that will recognize the distinction between objective knowledge and the realm of values–an ethic of knowledge that can, perhaps, save us from our deepening spiritual malaise, from the new age of darkness he sees coming.

Open Preview See a Problem? In the last portion of the book Monod gives some highly speculative musing on the jacqurs of human culture and language, cuance then gives a hard look at the harsh tension between objective knowledge and religious-humanistic ethics and values. There are no discussion topics on this book yet.

Even today a good many distinguished minds seem unable to accept or even to understand that from a source of noise natural selection alone and unaided could have drawn all the music of the biosphere.

The author continues to mention the sterospecific, spontaneous assembly of ribosomes and T4 bacteriophage from their protein constituents in vitro.

With mild treatment, protomers are separated and the oligomer protein loses function but, if the initial “normal” conditions are restored, the subunits will usually reassemble spontaneously.

Bipedalism freed the hands to hunt. The definition of life he puts forth in this book — those systems possessing teleonomy, autonomous morphogenesis, and reproductive invariance — is still the best I have ever heard, and I am ashamed that my teachers never taught it to me in high school. It was an assigned reading from a class at St. Chance and Necessity is a philosophical statement whose intention is to sweep away as both false and dangerous the animist conception of man that has dominated virtually all Western worldviews from primitive cultures to those of dialectical materialists.


The beauty of the book is that it situates the science of biology and the reality of the evolutionary process within its larger philosophical, historical, and conceptual contexts.

He then talks about the evolution of our ancestors including the development of upright posture which allowed them to become hunters. We are the ones who give it purpose, based on our billions of years of inherited molecular experience; we must keep our objectivity, and be careful not to confuse facts and jacsues. The author says that this animist belief is due to a projection of man’s awareness of his own teleonomic functioning onto inanimate nature. The formation of a sterospecific complex between protein and substrate and the catalytic activation of a reaction within the complex he stresses again that the reaction is oriented and specified by the structure of the complex.

But Monod’s work is one of the most original attempts to work out the philosophical implications of the modern synthesis in biology, and deserves more attention. He goes on to explain that it is marginal because the living world is only a fraction of the universe.

Chance and Necessity

Enzymatic catalysis is believed to result from the inductive and polarizing action of certain chemical groupings cjance the specific receptor. Values did not belong to him; they were imposed on him, and he belonged to them.

In doing this he engages with philosophical doctrines he thinks are misguided and proposes a doctrine of his own. Learn how and when to remove these template messages. Monod starts by considering the similarities and differences between three general kinds of things: So too we need to strictly separate facts and values in our search for the Truth.

Today he knows they are his and his alone, but now he is master of jacquez they seem to be dissolving in the uncaring emptiness of the universe”. Synthesis of mRNA is blocked when the repressor is bound to the operator.

It certainly took me long enough. Monod thinks that Christianity, Marxism and all other “animist” philosophies necessityy equally off-target.

Feedback activation is when the enzyme is activated by a product of degradation of the terminal metabolite. 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 starts off chapter I entitled “Of Strange Objects” with a consideration of the difference between natural and artificial objects and states that “the basic premise of the scientific method With that cliffhanger of internal intellectual struggle Monod ends chapter one.


Our existence neatly balanced between random chance as the source of possibilities and the conservative biological computational machinery that winnows those possibilities into survival and mpnod. Jeffery Mecessity, in the journal of Religion and Science, described the book as a “manifesto of materialist biology in the most reductivist sense”. No ideologue, Monod admits that objectivity itself has no objective premises, that it is in fact a moral position.

Monod explains that the rate of mRNA synthesis from the lactose operon determines the rate of the proteins synthesis. These simple molecular mechanisms account for the integrative properties of allosteric enzymes. This teleonomic principle stands in contrast, Monod argues, with vitalism and animism. At the present time we have no legitimate grounds for either asserting or denying that life got off to but a single start on earth, and that, as a consequence, before it appeared its chances of occurring were next to nil.

He says this “random” message seems to be composed haphazardly from a random origin and he ends the chapter poetically: By using this site, you agree to the Terms of Use and Privacy Policy.

Chance and Necessity by Jacques Monod

The author then writes that a primary structure exists in a single or a small number of related states, as is the case with allosteric proteins precisely defined conformational native state under normal physiological conditions. A classic meditation on evolution and the idea of randomness in natural selection.

People interested in Big Questions. If you can not face this, if you insist that your choice of value system is any less arbitrary than Monod’s own, if you cling to a “covenant” between man and the universe, then you will find Chance and Necessity unsettling. Because it is the foundation of science and science works. He believes that language was the key selective adaptation that led to the evolution of mind.

Through a series of thought experiments and rhetorical questions, he leads the reader on a difficult path to three moonod of living beings. Nature is explained with the same conscious and purposive manner as human activity. If you like books and love to build cool products, we may be looking for you.
