SUMMARY

The discussion centers on the philosophical implications of the Ship of Theseus as it relates to human consciousness and identity. Participants explore the idea that, similar to the ship, the human brain undergoes continuous replacement of its components, leading to questions about the persistence of consciousness over time. The conversation also touches on the hypothetical scenario of replacing brain parts with processors that mimic their functions, raising inquiries about the subjective experience of being a robot. Ultimately, the debate highlights the complexities of defining consciousness and identity in the context of physical change.

PREREQUISITES
  • Understanding of the Ship of Theseus paradox
  • Familiarity with concepts of consciousness and subjective experience
  • Basic knowledge of neuroscience and brain function
  • Awareness of philosophical discourse on identity
NEXT STEPS
  • Research the Ship of Theseus and its implications in philosophy
  • Explore theories of consciousness, particularly in neuroscience
  • Investigate the concept of identity in relation to physical changes
  • Examine advancements in brain-computer interfaces and their ethical implications
USEFUL FOR

Philosophers, neuroscientists, cognitive scientists, and anyone interested in the nature of consciousness and identity in the context of physical transformation.

I'm sure many of you have heard of the ship of Theseus. If not,

http://en.wikipedia.org/wiki/Ship_of_Theseus

"The ship wherein Theseus and the youth of Athens returned [from Crete] had thirty oars, and was preserved by the Athenians down even to the time of Demetrius Phalereus, for they took away the old planks as they decayed, putting in new and stronger timber in their place, insomuch that this ship became a standing example among the philosophers, for the logical question of things that grow; one side holding that the ship remained the same, and the other contending that it was not the same."
-Plutarch, Theseus

Now, you know where I'm going with this. The human brain is replaced one part at a time, and after about seven years, it contains no parts from the original. Most would agree that a human being's consciousness will survive after they have died.

When I say consciousness, I am talking about the purely subjective ability to experience experiences. After my brain has been replaced entirely, (hopefully) I will subjectively still experience being alive even though my brain has quite literally been turned into mush and replaced by a new one.

Now what if I create processors that can mimic the functions of parts of my brain, and replaced these parts one at a time? Would I eventually, subjectively get to experience being a robot?

I would hope that most would not agree.

I'm sorry but this does not meet the requirements for posting in philosophy.
