Exploring the Ship of Theseus and Star Trek Transporters

Chapter 1: The Nature of Identity
What defines an object as a unique entity? This question delves deep into the essence of identity, distinguishing one thing from another. When we consider objects like a boat or a house, what attributes make them individually identifiable? These age-old inquiries continue to puzzle thinkers today.
The Ship of Theseus serves as a classic thought experiment that challenges our understanding of "self" versus "not self." Imagine a vessel, which we'll refer to as The Boat. If a worn-out plank is replaced with a new one, can we still call it The Boat? Most would argue yes. However, what if half of the planks were swapped out? Is it still the same ship, or has it transformed into a different entity? If eventually every plank is replaced, many would contend that it’s no longer The Boat. Yet, I maintain a different perspective.
What if we disassembled the ship entirely? At that moment, it ceases to exist as The Boat. Even if we possess all its parts, the essence of The Boat is lost. This raises an important principle: an object is more than just the sum of its components. While we consist of atoms, we are not merely a collection of those atoms.
As long as there’s a continuous thread of time during which the identity of the self is recognized, the object remains the same. However, it must retain its fundamental characteristics; it should be identifiable as the same object at all moments.
To frame this idea mathematically, consider a group of interrelated parts forming an object. The identity of this group persists as long as only one part is altered, replaced, or rearranged at any moment, without changing the overall classification of the collection.
This explanation, while not entirely precise, captures the essence of the thought. For instance, a wrecked vessel still qualifies as a ship. Hence, if we rebuild it from its wreckage, it remains the same ship. The dilemma arises when we disassemble the ship completely and then reassemble it; it then loses its original identity, as it no longer holds its essential form.
However, there are complexities I am still grappling with. An object can embody multiple identities simultaneously. For example, a human can be seen as a person, an animal, and much more. Assuming that essential forms exist can provide a foundation for further exploration.
Section 1.1: Star Trek Transporters
The Ship of Theseus thought experiment primarily addresses inanimate objects, but human disassembly and reconstruction invites more intricate considerations. Star Trek presents a fascinating modern parallel with its transporter technology, where individuals are broken down into energy before being transported elsewhere.
If a transporter dismantles our physical bodies into fundamental components and then reconstructs us, we might argue that we are merely a copy. The original self is lost in the process. Interestingly, in the Star Trek universe, consciousness seems to persist even during transport. For example, in the episode "Realm of Fear" from Star Trek: The Next Generation, Lieutenant Barclay experiences a bizarre phenomenon while being transported.
Nevertheless, complications arise, likely stemming from narrative differences rather than actual discrepancies in the transporter technology itself. In the episode "Second Chances," an identical copy of Riker is left on a planet. This Riker leads a vastly different life from the one who returns to the ship. Determining which version is the "real" Riker becomes problematic. Based on the earlier discussion of transporters, it seems neither is devoid of their essential self, suggesting that both copies share the same identity.
Numerous thought experiments remain to be explored, and I intend to delve deeper into these concepts in the future. I also aim to refine my understanding of essential forms mathematically. What I have presented so far is not my final conclusion, but rather an exploration of a profound idea that has intrigued thinkers for centuries. I invite others to engage in this dialogue and share their thoughts.
The first video titled "Quantum Teleportation and the Star Trek Transporter" delves into the fascinating concepts of teleportation, linking theoretical physics with the iconic sci-fi technology.
The second video, "The Paradox of Theseus's Ship (90 Second Philosophy)," succinctly explains the Ship of Theseus thought experiment, illustrating the complexities of identity and change.
