Easily one of my top 10 favorite episodes.
The judge broached on the subject of what makes us distinct from Data (e.g. machines w/great heuristics) - the existence of a soul. Or rather, I'd like to think, in the words of CS Lewis, that we are a soul with bodies attached.
How would someone know whether one has a soul or not? Is there any sort of introspection that can reveal the presence of a soul or any of its properties?
Based on how some actual humans I know speak and act, I'm less and less convinced the human brain is much more than a stochastic next-thought prediction stream.
