     acquiring information is indisputably energy-consuming and conversely, the availability of information permits greater efficiency. strangely, the scientific community long remained reluctant to establish a physical equivalence between the abstract notion of information and sensible thermodynamics. however, certain physicists such as szilard and brillouin proposed: (i) to give to information the status of a genuine thermodynamic entity (k b t ln2 joules/bit) and (ii) to link the capacity of storing information inferred from correlated systems, to that of indefinitely increasing organization. this positive feedback coupled to the self-templating molecular potential could provide a universal basis for the spontaneous rise of highly organized structures, typified by the emergence of life from a prebiotic chemical soup. once established, this mechanism ensures the longevity and robustness of life envisioned as a general system, by allowing it to accumulate and optimize microstate-reducing recipes, thereby giving rise to strong nonlinearity, decisional capacity and multistability. mechanisms possibly involved in priming this cycle are proposed.
