The main thrust of the argument (one I agree with vociferously) is that life is not a category, it is either an aspect of every physical system or it is one pole of a very-hard-to-quantify spectrum of such systems. Another way to put it is, living is what systems do and some systems do more of it than others. There is much to say about intelligence in relation to life but best to stay on the latter for now considering this forum's apoplectic reactions to discussion on the former.
