Life as the Reduction of Entropy
During the present century a few physicists have tried to define life. Bernal, Schroedinger, and Wigner all came to the same general conclusion, that life is a member of the class of phenomena which are open or continuous systems able to decrease their internal entropy at the expense of substances or free energy taken in from the environment and subsequently rejected in a degraded form. This definition is not only difficult to grasp but is far too general to apply to the specific detection of...Definition of life as something that generates syntropy within itself while exporting entropy, and the problem with this definition as it would include fire and hurricanes as being living.

Lovelock Gets the Second Law of Thermodynamics Wrong
Let us again look at the laws of thermodynamics. It is true that at first sight they read like the notice at the gait of Dante's Hell; but in fact, tough as they are and although like income tax they cannot without penalyt be evaded, they can with forethought be avoided. The Second Law states unequivocally that the entropy of an open system must increase. Since we are all open systems, this means that all of us are doomed to die.He gets this backwards. The Second Law only applies to closed systems. We and our planet are not closed systems, we are open systems; therefore, mortality is not required of us. In fact, the second law states that, so long as we can keep exporting entropy by taking in energy from outside sources, we can live forever.
