Defining life: reductionist physics does not work (Introduction)

QUOTE: Life is a grab bag of different pieces, some of whose physical properties are easier to predict mechanistically than others, and it is certainly the case that at least some of the factors that matter a great deal to how a living thing works will fall into the category of highly non-universal emergent properties that are impossible to derive from first principles.

DAVID: The author's point is simple. Life is a emergent event=, which cannot be explained by reductionism and that applies to all thought about the origin of life.

A very stimulating article. If I were a cynic, I might point out that you can hardly be more reductionist than to claim that all the complexities of life can be explained by the existence of a single immaterial conscious mind that came from nowhere and knows everything and simply did it. But I am not a great supporter of –isms, trapped though I am in my agnosticism!

DAVID: I love his approach!!! Note the emphasis on the energy supply which I constantly bring up as ecosystems. Available energy drives life.

That is simply another way of saying that living organisms need food. I can’t imagine that anyone on this planet would disagree.
