Monod starts off the preface of the publication by way of asserting that biology is either marginal and valuable. He is going directly to clarify that it really is marginal as the residing international is barely a fragment of the universe. Monod believes the last word objective of technological know-how is to "clarify man's courting to the universe" (Monod, xi) and from that reasoning he accords biology a valuable function. He is going directly to kingdom that he doesn't have the desire to make an intensive survey of contemporary biology yet fairly to "bring out the shape of its key strategies and to show their logical relationships with different components of thought…it is an avowed try to extract the quintessence of the molecular idea of the code" (Monod, xiii). Monod stresses the significance of the molecular idea of the genetic code as a actual idea 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 percentage with and improve different disciplines of proposal akin to philosophy. towards the tip of the preface Monod bargains apology for any overly tedious or technical sections. He additionally warns that a few moral and political principles he provides could seem naïve or bold yet then states "Modesty merits the scientist, yet no longer the information that inhabit him and which he's lower than the duty of upholding"(Monod, xiv).

Because he saw it as jeopardizing the certainty that man and human thought are necessary end-products of a cosmic progress, Engels felt constrained to deny the second law. * Not until the second half of this century was the new anthropocentric illusion, propped up on the theory of evolution, to give way in its turn.
