Smurf said:Obviously it should be. Unfortunately our medical knowledge is no where near what we need it to be at in order to determine 'life'. We still need to make a decision though, so it falls to lesser disciplines.
It is not a medical debate, because medical sciences can only give us certain answers ONCE we've fixed the criteria of what specimens are entitled to "right to live". We first have to establish the criteria (if any!) on which to base our logic, and these criteria should be of general validity (and not beg the question), and justifiable for themselves, and not for the outcome.
An instance of a non-valid argument is:
- "human beings have the right to live" (why? - where does this come from ?)
- next, you can define "human being" the way you want, to include exactly those cases which you emotionally/religiously want to be included, and use *after the fact* some medical aspects to help you in your definition of "human being".
However, the real problem is: why does exactly that definition of "human being" for which you choose a medical definition, need to have a "right to live" and not other beings ? You can more or less arbitrarily define the words "human being", but then it is up to you to show why those specimen must have a "right to live". Or you can start with a general argument about what ought to have a "right to live", and then you have to show that whatever you define as "human being" satisfies exactly that argument. But in about all cases, you run into some troubles.
In other words, what we give "right to live" is essentially a purely social convention, with no deep philosophical or medical principle behind it. We only use philosophical or medical arguments *after the fact* to try to justify our purely social convention. The only exception to that is religious doctrine, where your favorite deity did the thinking for you, and just gave you the rule.
EDIT: for instance, you use the term "life". Although there are instances where science has some difficulties deciding whether certain processes should be included in the *definition of the word* "life" (like virusses), concerning human beings, there's no discussion. Even white blood cells are "life". So this criterion is useless, because bleeding is already "murder" in that case.
The same applies to "contains the entire human genome". Apart from the reason why this should be any criterion to "protect against murder" (after all, what's so special about human genome: an order of base pairs with a certain variability to it), white blood cells also contain the entire human genome. A chimp has about 95% of genome in agreement with a human being. So how does it work out for a chimp then ?
But maybe with "life" you actually mean "conscious life". Well, as I pointed out, a mature dolphin has more "self-awareness" than a new-born baby. But also certain birds and certain monkeys, and elephants. So why don't we include them then in our list ?
Maybe we should talk about suffering. Does that mean then that murder is ok, if we don't make the victim suffer ?
You see, it is far from easy to establish a universal criterium on which to base all deduction to the "right to live".
