The analogy fails because direct abortion is the intentional taking of an innocent life. Trying to save all, as in the fire scene, is simply not the same moral issue.
So why did you modify the fire scene analogy with another analogy of your own. No analogy is exactly like the situation it is compared—that why it is called an analogy. And an analogy does not “fail”—because no analogy provides proof of anything, it is either a “weak” analogy or a “strong” analogy giving support of why one situtation should be seen the same as the other (even though they are different in some respect).
The first analogy was an attempt to show that (in that poster’s view) that the fertilized egg is not of equal value as a born adult by placing both in a fire scene. You indicated that your analogy would not prove " the unconscious ones were not really persons or do not deserve to be protected? "
(Your analogy is not clear–could not the conscious one jump on his back and grab at least one of the unconsious ones?)
Well, the first analogy does not lend support to the first poster’s conclusion that the one subset of life is more valuable than the second subset of life, but rather supports the notion that, given the two in that situation, requires making choices about what type of protection each subset of lives get.
The firefighter grabs the live person, and accepting the eggs are life too, goes back in, only if able, to grab the eggs.(But given the analogy we assume he will not be able to go back in.) Thus, he makes the decision—a trade off–and basing it on the view that the born person deserves the priority of protection in this situation—not because he does not see the eggs as life or not valuable or even less valuable because he would go back in the house if he could. (If your two kids are drowing and you can only save one, does not mean you did not equally value the life of the other one lost)
The early fetus in a women. Well society wants to protect that early fetus but believes criminalizing all abortions under all circumstances strains resources (prosecution and jail space) that are better spent protecting society from violent criminals. (a women who commits an abortion is not the violent threat to others that a gun holding robber is)
Further, expanding govt police power is dangerous because govt police power is one of the main threats to individual liberty, as well as the notion that govt does not get to make all decisions in this society—the women’s duty (individual responsibility) here—the fetus is inside her.
So society uses, other, non coercive means (many more which are needed) to attempt to protect the early fetus by convincing the women to make a better decision. But does criminalize later terms abortions----it just shocks the conscience at this point and the women’s exclusive duty time is up.
Society does not value the early fetus less, nor does not recognize it as life, but rather recognizes the different situations between the early fetus and a born person and employs different means to attempt to protect both. With the early fetus, other considerations come into play as noted above------thus the reality of trade-offs.
The first analogy is good to show how trade-offs happen given the reality of the situation. Though, in the analogy, no effort is made to protect the eggs where efforts are employed to help the early fetus (not enough though). Well, we could say the the building meeting the fire code would be some effort for the fertilizeed eggs.
You can disagree and say the means should be the same for both the early fetus and the born adult despite resources and concerns of govt power-----fine your opinion.
But you cannot ignore the trade-offs and you cannot assert that another position that supports different means to protect both subsets of life, justified by the different conditions, necessarily means that position sees the one life less than the other life---- but again recognizes the trade-offs that reality creates given limited resources and other values that need promotion. The fire analogy helps because it starkly shows a trade-off in action.
