On the one hand, a main theme here is theories of consciousness. On the other hand, it’s been almost eight years blogging, and I’ve covered my views pretty well in numerous posts and comment threads. Our understanding of consciousness currently seems stuck pending new discoveries, either in answering hard questions, or in providing entirely new paths.
A while back I determined to step away from debates (even blogs) that center on topics with no resolution. Religion is a big one, but theories of mind is another. Your view depends on your axioms. Unless (or until) science provides objective answers, everyone is just guessing.
But it’s been three-and-a-half years, and, well,… I have some notes…
In Greek mythology, the hero Theseus, who slew the Minotaur and escaped its maze, returned from Crete to Athens where the Athenians preserved his ship in seaworthy state for more than a thousand years. It was an emblem of courage and a reminder of a national hero that many Greeks considered more legendary than mythological.
The Ship of Theseus was carefully maintained. Parts that rotted away were replaced with exact replicas. And in a ship made almost entirely of wood, crude iron, rope, and sail, everything rots, so eventually everything gets replaced.
Which makes the identity of the ship an interesting question.
Over the last few weeks I’ve written a series of posts leading up to the idea of human consciousness in a machine. In particular, I focused on the difference between a physical model and a software model, and especially on the requirements of the software model.
The series is over, I have nothing particularly new to add, but I’d like to try to summarize my points and provide an index to the posts in this series. It seems I may have given readers a bit of information overload — too much information to process.
Hopefully I can achieve better clarity and brevity here!
Over the past few weeks we’ve explored background topics regarding calculation, code, and computers. That led to an exploration of software models — in particular a software model of the human brain.
The underlying question all along is whether a software model of a brain — in contrast to a physical model — can be conscious. A related, but separate, question is whether some algorithm (aka Turing Machine) functionally reproduces human consciousness without regard to the brain’s physical structure.
Now we focus on why a software model isn’t what it models!
This may be the first actual Brain Bubble I’ve ever posted! The original intent was to provide a mechanism for sudden (short) thoughts I wanted to record or put out there. But the BB posts quickly turned into mini collections of thought bubbles.
But today I started trying to get into Immanuel Kant (again), and that naturally led to a bit of Wiki Walking.
It was when I got to the article about the subject-object problem that a sudden brain bubble burst!
