seebs: ... and "survival of the fittest" is an observation about how animals live, not a moral ideal.
DNAunion: Humans are animals. So survival of the fittest - the underlying law of all biology - applies to us. Why should we not leverage that law of nature to its utmost, as long as we don't break any laws? Survival of the fitttest then becomes directly tied to a moral issue.
seebs: This is one of those "silly" things. Reproductive fitness determines whose genes are passed on, but that's not a law in the sense of a normal law; it's a description, not a prescription.
DNAunion: I didn't say it was a moral law. Look at the above exchange again. You said survival of the fittest was not a moral ideal, and nothing I stated said otherwise. I said it could be
tied to a moral issue; that one could try to leverage the idea to his/her advantage.
The distinction between pure science and applied science comes into play here. Pure science is aimed at extending our knowledge: learning more about how nature works. Applied science is the taking of scientific knowledge and applying it to a given problem in order to solve it. For example, that the acceleration of an object is proportional to net force applied to it is an observation about how objects respond to forces: it's also half of Newton's second law of motion. Now, when we take that preexisting scientific knowledge and apply it to solving a given problem -- such as lauching a rocket -- we are "leveraging" our understanding of nature/science for our own advantage.
We have applied Newton's second law to rockets, but that does not mean we are saying that Newton's second law of motion is a rocket.
A form of "applied science" is what I am talking about. Survival of the fittest is a "law" of biology. One could try taking it and applying it to solve a problem involving things that fall under its domain. That would not make survival of the fittest a moral ideal, any more than applying Newton's second law of motion to rockets makes Newton's second law of motion a rocket.
Seeb: The law of gravity doesn't mean we *SHOULD* go to lower places; it means that, in the absence of supports, we tend to fall.
DNAunion: Actually, we have a tendency to "fall" even when their are supports present. And when there are no supports, you should not only
tend to "fall", you should
actually "fall". The tendency and the behavior of an object do not have to be the same.
seebs: The "law" of biology (which is hardly as simple as your portray it as boing) doesn't mean we *SHOULD* compete like that.
DNAunion: You are comparing apples and oranges.
Of course the law of gravity doesn't tell us how we should live our lives. Why should it? The law of gravity is not what is responsible for our being, or our becoming, humans (I've never heard a scientist say, "Nothing in biology makes sense except in the light of gravity").
It is evolution -- not gravity -- that is responsible for our being what we are. If one is going to try to apply knowledge from some area of science to the issue, then the correct one is evolution/biology.
Also, note that I am not saying that evolution is immoral or that survival of the fittest is a moral ideal. Nor am I saying that survival of the fittest tells us we *SHOULD* act in a "self-promoting at the expense of others" way. I am playing Devil's advocate.
