Identity, teletransportation and philosophy by sci-fi

Is our personal identity just the particular make up of our physical bodies at a particular point in time? And if so, would a teletransporter that replicated our physical bodies on Mars preserve our personal identity? Thought experiments and transhumanist sci-fi technological dreams such as this are deceptive means of doing philosophy and should be kept in Hollywood and marketing campaigns, writes Nicholas Agar. 

 

In his 1984 philosophical classic Reasons and Persons Derek Parfit tells a story about a fantastical futuristic technology – the Teletransporter. 

 

I enter the Teletransporter. I have been to Mars before, but only by the old method, a space-ship journey taking several weeks. This machine will send me at the speed of light. I merely have to press the green button. Like others, I am nervous. Will it work? I remind myself what I have been told to expect. When I press the button, I shall lose consciousness, and then wake up at what seems a moment later. In fact I shall have been unconscious for about an hour. The Scanner here on Earth will destroy my brain and body, while recording the exact states of all of my cells. It will then transmit this information by radio. Travelling at the speed of light, the message will take three minutes to reach the Replicator on Mars. This will then create, out of new matter, a brain and body exactly like mine. It will be in this body that I shall wake up.

Though I believe that this is what will happen, I still hesitate. But then I remember seeing my wife grin when, at breakfast today, I revealed my nervousness. As she reminded me, she has been often teletransported, and there is nothing wrong with her. I press the button. As predicted, I lose and seem at once to regain consciousness, but in a different cubicle. Examining my new body, I find no change at all.

 

Parfit uses the teletransporter story to launch a philosophical assault on common-sense beliefs about what we are. A series of variations of the teletransporter story demonstrate that we are not individuals whose survival consists in the preservation of our personal identities over time. The seemingly earnest question – ‘after many years of Alzheimer’s disease would it still be me?’ – relies on a false assumption.  

I think we should view Parfit’s story as a comparatively early instance of philosophy by sci-fi. And for that reason, we should distrust our intuitive reactions to it.

These are far-reaching challenges to common-sense about what we are, all on the basis of a fantastical story. I think we should view Parfit’s story as a comparatively early instance of philosophy by sci-fi. And for that reason, we should distrust our intuitive reactions to it. 

We are a long way off teletransporting persons. But the teletransporter doesn’t seem to violate any law of physics. There are proofs of concept in the quantum world in which the state of one particle can be instantaneously teleported to another by way of quantum entanglement. A retelling of Parfit’s story that was a bit more focused on the science might count as hard science fiction. We might compare it with the more pessimistic account in Kameron Hurley’s 2019 novel The Light Brigade. Her teletransportees suffer a variety of accidents more upsetting that any Parfit describes. They arrive on planetary surfaces missing vital organs or with their memories scrambled. 

Parfit is a philosopher, not a sci-fi author. It’s nevertheless worth asking what the teletransporter story really shows. What support does it offer to the conjecture that humans survive copying? Note the question-begging use of the first-person singular pronoun. There’s a convention in autobiographical writing that the referents of “I” don’t abruptly switch mid-story. But of course, that’s exactly what’s at issue here. Suppose Parfit had called his machine “the Person-Generator” and told it this way – “I emerge from the Person-Generator on Mars with all of the beliefs and memories of a recently killed Earthling. A quick lecture on the operation of the machine reassures me that these symptoms of identity-disorientation will progressively fade. Fortunately, there is a recently bereaved woman on Earth who I’m told will find me quite sympatico.” There need be no difference in the operation of the Person-Generator or the teletransporter apart from claimed effects on identity. One kills you and the other doesn’t. 

 In her 1993 book Real Persons the philosopher Kathleen Wilkes cogently challenges the distorting effects of sci-fi stories on our understanding of our personal identity. But such is the power of the teletransporter story, complete with all of its fun sci-fi connections, that it continues to occupy a central location in first year philosophy lectures. We obligingly forget all of Wilkes’ warnings. 

Dan Zahavi, Lisa Bortolotti and Anders Sandberg debate the nature of the self.

I propose that we are inclined to interpret the story as Parfit prefers for reasons that are more about cultural context than anything especially philosophically deep. Parfit’s is a cooler story than Wilkes’. Teletransporters entered public awareness as the teleporters of the TV series Star Trek. Parfit describes an event that we all think we’ve seen Captain Kirk survive many times. For lecturers of first year philosophy classes that linkage is gold. You could start your fresh-faced students off with some tortured prose on the self from Immanuel Kant’s Critique of Pure Reason or you can talk Star Trek. It’s interesting to speculate about how Parfit’s story would had been received – or whether it would have occurred to him to offer it – had not budgetary constraints forced Star Trek creator Gene Roddenberry to abandon his original plan of having the characters arrive on planet surfaces by landing the entire Starship Enterprise. Parfit belabours his preferred philosophical interpretation by redubbing Star Trek’s teleporter the teletransporter. 

Philosophy by sci-fi sends a deceptive message when applied to familiar ideas about what kinds of beings we are. You might ask what the problem is if people end up with some odd beliefs about what they are. Messing with received wisdom is, after all, part of the philosopher’s job description. I think philosophy by sci-fi has an altogether more pernicious effect in other domains. 

Philosophy by sci-fi is a mainstay of the arguments of transhumanist philosophers. According to transhumanists we should apply a variety of fast improving genetic and cybernetic technologies to ourselves. These will make us post-human. According to the Transhumanist FAQ, becoming posthuman could enable us to: 

 

…reach intellectual heights as far above any current human genius as humans are above other primates; to be resistant to disease and impervious to aging; to have unlimited youth and vigour; to exercise control over their own desires, moods, and mental states; to be able to avoid feeling tired, hateful, or irritated about petty things; to have an increased capacity for pleasure, love, artistic appreciation, and serenity; to experience novel states of consciousness that current human brains cannot access. It seems likely that the simple fact of living an indefinitely long, healthy, active life would take anyone to post-humanity if they went on accumulating memories, skills, and intelligence.

 

This enticing story describes a logically possible future. It doesn’t seem to violate laws of physics. The problem is that it is much more an exercise in marketing than the balanced philosophical appraisal that we need right now. 

As we are entering an age of human enhancement, we should beware philosophers using sci-fi to market their own particular visions of the future.

Human enhancement technologies have travelled the path from fun sci-fi to the Amazon marketplace. Nootropics, drugs marketed as enhancing memory and other cognitive capacities are available for sale, some with quite eye-watering prices. Transhumanist stories are excellent marketing for “Neurohacker Collective Qualia Mind Qualia Mind Nootropics – Top Brain Supplement For Memory, Focus, Mental Energy, And Concentration With Ginkgo Biloba, Alpha Gpc, Bacopa Monnieri, Celastrus Paniculatus, Dha & More” on sale at Amazon for US $199.92

If a philosopher of sci-fi is interested in marketing a vaccine, they can tell a story in which it has 100% efficacy and causes no side effects. Perhaps such stories can help persuade a few anti-vaxxers that vaccines are not necessarily evil. But as we confront actual vaccines with actual side-effects, we need philosophical appraisals that encourage us to balance real benefits against real risks. We don’t need optimistic sci-fi about perfect vaccines. As we are entering an age of human enhancement in which the Amazon marketplace is likely to offer ever more ways to enhance ourselves, we should beware philosophers using sci-fi to market their own particular visions of the future.

Suppose some unexpected scientific breakthrough does enable us to do to entire persons what physicists can now do to particles. You sight a candidate for the procedure with a dog-eared copy of Reasons and Persons. Warn them that what makes for cool 1960s sci-fi may not describe what actually happens when you use the technology. At least pass them copies of Wilkes’ Real Persons and Hurley’s The Light Brigade. These gifts could save their lives.

Hmm, interesting enough. Have you heard something about the teletransport paradox? It is a thought experiment in philosophy of identity that challenges conventional intuitions about the nature of the self and consciousness. The founder of the Scottish School of Common Sense, Thomas Reid, wrote to Lord Kames in 1775: “I would be glad to know your Excellency's opinion on the following: when will my brain lose its original structure and when, hundreds of years later, an intelligent creature will be created from the same material in an amazing way , can I consider him myself? Or if two or three such creatures are created from my brain, then can I believe that they are me, and, therefore, one and the same intelligent creature? " I gathered this information from scientific posts on Twitter in which scientists and philosophers talk about the nature of life. There you can find a couple of hundred posts on this topic and I noticed that most of them are posted by accounts that have about 93 thousand subscribers! I am sure this is because the owners of such accounts used the services of https://viplikes.net/buy-twitter-followers in order to increase the number of subscribers.
