Living vs non living maerial, define what alive means. Th difference between a cell, a rock, and a cat, and a plant.
Is a single cell aware of its surroundings?
It looks like you are trying to eliminate the field of philosophy.
Philosophers spend all their time using such terms (along with terms such as moral) in elaborate and convoluted argumentation without ever defining what the hell they mean by the terms. Define the terms and require all philosophers to use the definitions and they will no longer have any arguments to offer. They will have to look for something useful to do to earn a living. Maybe they will have to learn the phrase, "do you want fries with that".
I usually like your posts, skepticalbip, but I have to say that in this I just don't agree. I've read quite a lot from quite a lot of philosophers, and in fact I cannot recall a single one of any import who did not define their terms. I know for a fact that Spinoza went to great lengths explaining precisely what he meant by the terms he used, since I've read all of his philosophical works. This DOES NOT mean that one is forced to agree with those definitions, of course, and Spinoza is known for having some rather eccentric definitions of certain terms. I've read some Kant and Hegel, Berkeley, Hume, a lot of Thomas Reid (who I think levels Hume and Berkeley flat and was duly forgotten for his efforts), Descartes, Sartre, Nietzsche, Aristotle (though I will admit his Analytics are so far over my head it's ridiculous, though his ethics and metaphysics are approachable to a layman), some Plato, etc, etc...
I have read a lot of philosophy which I have found to be remarkably silly: pure castle building (castles in the air), a phrase/idea Thomas Reid used to refer to the Idealists.
I have also read some that I found utterly inscrutable, like some of Wittgenstein, most of Kant and Hegel, actually; and especially Derrida.
I have read some which is so inscrutable, so deliriously convoluted, it was more funny than anything else: lots of theology and cosmology appears funny to me, or a lot like science fiction.
But all that aside, I see no major philosopher who just tosses out terms without defining them. I see absurd definitions, or ones which I cannot grok at all, or ones that seem ridiculously simple, as in G.E. Moore and Searle, plus others.
