I agree, and I would add that we have nothing but intuition to go on when deciding on such a definition. A counterintuitive definition is undesierable because it would undermine the respect for the social convention, thus making it more likely that people would fail to conform to it.
If we agree that the "magic line" sepparating realized persons from potential persons is a human construct we should be able to agree that the "err on the side of caution" argument is moot. The point of contention is not where the line runs, it is where to draw it.
I'd also like to put to rest a couple of other issues on which I believe there is widespread agreement.
Do we all agree that it is not reasonable to consider it unethical to deprive an unrealized person from becomming a person? That is, for the segment who assign personhood upon conception, do you agree that it would not be unethical to prevent a conception, thus preventing the realization of a potential person?
Do we also agree that the status of person is retained until one can rule out that the criteria for personhood will ever again be fulfilled? If the criteria is live, would you agree that clinically dead people who have a fighting chance at being brought back retain their status as person?
And do we agree that once it can be determined that an organism will never again fulfill the criteria for personhood, harvesting organs to save others is not unethical? (allowing for people to legaly excempt themselves when alive)
