“…But the problem is that the probabilistic view is often very successful, considering for example its singular capacity to simply rule out the Gibbs paradox without denying classical particle individuality. We are aware that decreasing entropy in equilibrium conditions is a Graal of thermodynamics, considered as heretic, following the opinion of Sir Arthur Eddington "If your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation" (Eddington, 1930). Hence in an attempt to avoid humiliation, let us immediately precise that the second law of thermodynamics is not challenged but refined by incorporating information as an additional component of a generalized Carnot principle (section 5.5).…”

An essential step towards understanding life would be to identify the very basic mechanisms responsible for the discerning behaviour of living biochemical systems, absent from randomly reacting chemical soups. One intuitively feels that this question goes beyond the particular nature of the biological molecules and should relate to general physical principles. The preeminent physicist Ludwig Boltzmann early envisioned life as a struggle for entropy, in concordance with the subsequent principle of self-organization out of equilibrium. Reexamination of elementary steady state biochemical systems from a statistical perspective supports this view and shows that sigmoidal responses arising from microstates elimination, are sufficient to explain innermost characteristics of life, including its capacity to convert random molecular interactions into accurate biological reactions. A primary operating strategy to achieve this goal is the introduction of time-irreversible transitions in molecular state conversion cycles by injection of free energy, which confers decisional capacity to single macromolecules. Selected examples from various fields of molecular biology such as enzymology and gene expression, are provided to show that these non-equilibrium steady state mechanisms remain important in contemporary biochemical systems. But in addition, information archiving allowed the emergence of the time-reversible counterparts of these mechanisms, mediated by evolutionary preorganized macromolecular complexes capable of increasing discernment in a non-dissipative manner.

“…Additionally, it would be desirable to characterize system (II) considered in this research from the standpoint of thermodynamics as loop (closed) system because the system which cannot exchange matter with environment is called closed;-the only exchange of energy is possible (Prigogine and Defay 1954;Kondepudi and Prigogine 1998). Let's consider in our case a thermodynamic indicator ''entropy'',-which is the index of evolution, or according to Eddington ''time arrow'' (Eddington 1928). Thanks to entropy, the system in which there is initially a chaos, aspires to an equilibrium state and to the answer energetically adequate to external influence.…”

This research is devoted to possible mechanisms of decision-making in frames of thermodynamic principles. It is also shown that the decision-making system in reply to emotion includes vector component which seems to be often a necessary condition to transfer system from one state to another. The phases of decision-making system can be described as supposed to be nonequilibrium and irreversible to which thermodynamics laws are applied. The mathematical model of a decision choice, proceeding from principles of the nonlinear dynamics considering instability of movement and bifurcation is offered. The thermodynamic component of decision-making process on the basis of vector transfer of energy induced by emotion at the given time is surveyed. It is proposed a three-modular model of decision making based on principles of thermodynamics. Here it is suggested that at entropy impact due to effect of emotion, on the closed system-the human brain,-initially arises chaos, then after fluctuations of possible alternatives which were going on-reactions of brain zones in reply to external influence, an order is forming and there is choice of alternatives, according to primary entrance conditions and a state of the closed system. Entropy calculation of a choice expectation of negative and positive emotion shows judgment possibility of existence of ''the law of emotion conservation'' in accordance with several experimental data.
