He wrote I originally intended to write a book about intercellular communication:— about how the cells in an organism exchange information among each other—a question I had worked on for the past thirty years. But as I got to the heart of it, which required me to track the spoor of intercellular information to its source, a picture materialized seemingly out of the blue: a continuous intra- and intercellular communication network where, with DNA at the core, molecular information flowed in gracefully interlaced circles.

That apparition had an allure I could not resist, and so this became a book about information. I was twice fortunate. Second, information theory, a thriving branch of mathematics and physics, allowed me to view this information flow in a new light. I shall argue that this information flow, not energy per se, is the prime mover of life.

The Touchstone of Life , p. But then Loewenstein starts to claim there is a "fundamental randomness that is above thermodynamic equilibrium, a randomness encompassing a spectrum of information-containing states. Let us summarize then what transpired about randomness from our discussion about chaos and information. Above thermodynamic equilibrium there are two kinds of randomness: one for the microscopic state at the quantum level, as embodied by the Heisenberg principle, and one for the macroscopic state at the level of deterministic chaos.

There is another type of fundamental randomness, of course, the one prevailing at thermodynamic equilibrium. But this type is utterly run-down and, in a book on information, we are entitled to snub something that has sunk so low. Now, what of the old polemic about determinism and chance, the dispute that has been going on in philosophical circles since the time of the ancient Greeks to the present.
