What is life?

I continue to read the book “Soul Machine” (a cultural history of the mind) and continue to get this sense that many of the philosophical quandaries of today were struggled with hundreds of years ago. For instance, in a recent acid logic article I reported on various theories that argued that life was not a distinct state separate from non-life. I quoted an article in a science magazine on a fellow who argues that what separates living things from the non-living is merely a matter of how the atoms of each structure were organized. He has derived a mathematical formula which…

…indicates that when a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy. This could mean that under certain conditions, matter inexorably acquires the key physical attribute associated with life.

This is written as if it is a new revelation (and in fairness, the details are.) But check out this passage from the book on the work of a German philosopher Reil who lived during the 18th century.

Reil discounted a number of theories and proposed that through a process of complex self-organization—his favorite metaphor was the process of crystallization—chemicals developed new properties that somehow made for living matter.

They aren’t quite the same theories—one describes the atomic level and the other chemicals—but there are a lot of similarities.
