Excellent. What I was going to post would have been redundant pleonasm, not to mention superfluously excess.

I would like to add a reference to Luisi's paper: About various definitions of life. (The link is to a .pdf in a journal.) There's also a new book by Robert A. Freitas, Kinematic Self-Replicating Machines, which addresses definitions of life with a lot of discussion about the difference between reproduction and replication.

I cannot get the link to work and would be very much interested in reading the article. Perhaps it is only busy, but would you mind checking the link anyway?
