Abstract



Research Methodology

Links to Notes
  1. Propriety of Thought Experiments3
  2. Principal Examples:-
  3. Transhumanism16
    → Cyborgs17
    → Androids18
    → Chimeras19
  4. Others?


Chapter Introduction
  1. In this chapter we will consider all the usual suspects, as itemised in the list of Notes above.
  2. It is to be noted that some – in particular Commissurotomy – are more actual experiments than thought-experiment, though quite a lot of armchair thinking is involved in working out their import.
  3. Pregnancy and birth in placental mammals might be described as fusion followed by fission.
  4. Multiple Personality Disorder is again – at least allegedly – an existent pathology rather than a Thought Experiment. Moreover, it might be better situated in Chapter 920 as a critique of the idea of an individuating First-Person Perspective21.
  5. Brain Transplants come in various forms. We need to distinguish Whole-Brain Transplants (WBTs) from single or double Cerebrum transplants, and these from brain-tissue transplants, which shade off into Siliconisation and Brain State Transfers.


Main Text
  1. To be supplied22.


Concluding Remarks
  1. Having now discussed Thought Experiments in general, we now in our next Chapter23 turn to the question of Resurrection – the matter that first motivated Locke (and – I suspect - Lynne Rudder Baker and many others) in their discussions of Personal Identity.
  2. This is work in progress24.


Links to Books / Papers to be Addressed25
  1. In this Chapter I will consider the following papers or book chapters (together with some others referenced by these). There are doubtless many more that are relevant and which will be addressed in the course of the thesis, but these are probably sufficient to get us going.
  2. I have segregated the papers by sub-topic, but some would fit into more than one category.
  3. Theory
  4. Brain State Transfers26
  5. Brain Transplants
  6. Commissurotomy
  7. Fission
  8. Fusion
  9. Multiple Personality Disorder
  10. Replication
  11. Siliconisation27
  12. Teletransportation
  13. Transhumanism29
  14. Many aspects of these papers will need to be either ignored or reserved for other chapters.
  15. The motivation for these works is as follows:-
    • To be supplied.


The Cut
  1. There had already been a lot of cutting in the various selections of the original reading list – the reading lists attached to the Notes run on and on – and these items just represent the works in my possession (though I have sought out all that I’ve heard of that look relevant).
  2. However, the items in the lists following were given some attention, and have been culled – at least temporarily – from the lists above, where they originally appeared. I’ve not always given a reason as I’ve not studied them sufficiently closely. But, you have to draw a line somewhere.
  3. I’m well aware that the cut has not been sufficiently rigorous. Further items beyond the items below are likely to be culled when I come to process them.


In-Page Footnotes:

Footnote 25: Footnote 26: Footnote 27: Footnote 28: Footnote 29: Footnote 30: I’ve read this book, but it’s insufficiently philosophical for its arguments – such as they are – to be worth considering as a priority.

Footnote 31: Cover in the next Chapter.
