I have a strong feeling I'm going to regret getting involved in this, but ...
Can somebody define the criteria of "alive" - what must something possess to be a living entity?
Until you have a solid understanding of what "alive" means, we cannot debate this any further - my definition is this ....
What you're doing here is taking a term--in this case "alive"--and arbitrarily assigning a definition to it while neither clearly detailing and defending the reasoning behind your
inclusions of the specific attributes of the thing you're defining, nor your
exclusions of the objectionable attributes found in the standard definition. It's like taking the term "apple" for example, and saying, "You've heard the
Fruit Fraternity dictate what an "apple" is to the masses.
But I say an apple is a conglomeration of sugar molecules, vitamins and minerals that undergoes chemical processes while suspended above the ground for an extended period of time, and therefore ...." with no explanation of where this is coming from, why the standard definition of "apple" isn't sufficient, who the members of the Fruit Fraternity are, and exactly what the secret agenda behind its imposition of the standard definition is.
It just ends up sounding silly.
A good definition for "alive" that is deduced from observing nature might be,
That body is alive which is animated by a soul, or the first principle of life. (The nature of that soul is a whole other debate...promise I won't even try to go there.) To quote Aquinas,
For it is clear that to be a principle of life, or to be a living thing, does not belong to a body as such; since, if that were the case, every body would be a living thing, or a principle of life.
My neighbor's cat is alive now because of the presence of a soul--the first principle of life--which animates him. If he gets run over by a car, his living body will become a dead body--absent the presence of a soul. If his soul were not the first principle of his life, then I might be able to say he's actually still alive, in spite of the tire treads running the length of his body.
But roadkill is dead, period! In fact, ALL dead bodies are not alive, just like rocks and snowflakes and sea foam are not alive; otherwise they would have to be their
own first principle of life.
Okay, I asked for it: now show me how stupid I am. I had fun trying, though :
St. Thomas Aquinas *(Before you get all hacked off, you've got to admit he was quite a smart guy--
and, let's not forget, an especially big fan of the guy on the far right, who also had some dynamite dendrites ....)
