Monod begins the preface of the ebook via asserting that biology is either marginal and relevant. He is going directly to clarify that it's marginal as the dwelling international is just a fragment of the universe. Monod believes the final word target of technology is to "clarify man's courting to the universe" (Monod, xi) and from that reasoning he accords biology a crucial function. He is going directly to country that he doesn't want to make a radical survey of contemporary biology yet particularly to "bring out the shape of its key strategies and to indicate their logical relationships with different parts of thought…it is an avowed try to extract the quintessence of the molecular thought of the code" (Monod, xiii). Monod stresses the significance of the molecular concept of the genetic code as a actual thought of heredity and types it because the "secret of life". He maintains to provide an explanation for how this crucial discovery has made it the obligation of scientists to proportion with and improve different disciplines of suggestion corresponding to philosophy. towards the top of the preface Monod deals apology for any overly tedious or technical sections. He additionally warns that a few moral and political rules he offers could seem naïve or bold yet then states "Modesty advantages the scientist, yet no longer the information that inhabit him and which he's below the duty of upholding"(Monod, xiv).

33 C h a n ce a n d N ecessity Hegel's postulate, that the most general laws governing the universe in its evolution are of a dialectical order, is in its proper place within a system which acknowledges no permanent and authentic reality except mind. If all events, all phenomena are but partial manifestations of “an idea that thinks itself,” it is legitimate to look for the most immediate expression of the universal laws in our subjective experience of the thinking process. And since thought proceeds dialectically, “the laws of the dialectic'’ govern the whole of nature.

I shall devote the remainder of this chapter to a schematic analysis of the logic of these interpretations, very diverse in appear­ ance but all implying the renunciation, partial or total, 24 Vitalisms a n d Animisms admitted or not, conscious or otherwise, of the postulate of objectivity. It will be convenient here to classify these concepts (rather arbitrarily, it is true) under one of two headings, according to the nature and supposed extension of the teleonomic principle they invoke. ” These theories, which 1 shall call vitalist, therefore imply a radical distinction between living beings and the inani­ mate world.

These to be sure do not violate the laws of thermodynamics, quite the contrary. They not only obey them; they utilize them as a good engineer would, with maximum efficiency, to carry out the project and bring about the “dream” (as Francois Jacob has put it) of every cell: to become two cells. , in the construction of cellu­ lar organelles. There is, however, no physical paradox in the invariant reproduction of these structures: invariance is bought at not one penny above its thermodynamic price, thanks to the perfection of the teleonomic appara­ tus which, grudging of calories, in its infinitely complex task attains a level of efficiency rarely approached by man-made machines.
