Feedback for my essay on Philosophy Paper relating to parfits personal identity [3]
Your argument seems sound, and I agree with your conclusion. However, some things to consider:
1) All three Harrison's materialize in different locations (however slightly). Thus, the very act of materializing is a different experience for each, and by the time they realize what has happened, each is therefore already slightly different from each other.
2) Here is a thought experiment for you:
Let us say that the original Harrison owns a precious statue. This statue is not precious in a material sense, being made only out of cheap plaster. But, this particular statue was given to him by his mother the day before she died, and so has great sentimental value for him. By odd coincidence, the plaster from which this material is made prevents it from being replicated by transporter or replicator technology. Replicas could be hand-made, of course, but duplicating the exact color of the plaster is impossible, against due to the mysterious impurities in the original plaster, so it is impossible to create perfectly exact duplicates.
Now, let us say that, after being split into three Harrisons, the thee are so horrified at seeing themselves as others see them that they cannot bear each other's company, and so all choose to go to completely different sections of the universe.
Which Harrison gets to keep the statue?
Remember, there can only ever be one that has any meaning for the Harrisons. You could, I suppose, have the Harrisons choose by lottery who gets to keep it. But, if possession of the statue is an integral part of what makes Harrison Harrison, by Harrison's own understanding of who he is, does the very act of assigning the statue to one of the three make that one more truly Harrison than the others?
3) Same thought experiment as above, only substitute a girlfriend(or wife!) for the statue, and assume you cannot replicate the malfunction. Who continues in the relationship? Which one, in the case of a wife, is the woman married to? Is she now guilty of bigamy? And if the Harrisons decide to get as far away from each other as possible, who does she go with? Does she have to divorce the other two?
The point of the two thought experiments is that, while in theory the three Harrisons may be equally you, as you claim, in practice one is going to end up being more equal than the others. I think a strong conclusion might be one that would deal with how you would handle this.
