The meaning of "knowledge"

Hypothetical:

In Town X, a burglary is reported to the police. They investigate, and their investigation leads to Bob, who has previous convictions for that sort of thing. They find the stolen goods at Bob's house, Bob is questioned, he confesses, it goes to trial, Bob pleads guilty, the jury is convinced by the evidence, and Bob is sentenced accordingly.

In fact, Bob had not committed the burglary. In fact, he had a provable alibi - he was out committing another burglary (of equivalent severity) elsewhere in town at the time. The original burglary was done by a friend of his, and he was just storing the goods at his house. Given that demonstrating his alibi wouldn't have saved him any prison time, and would have involved fingering his accomplices (which would have damaged his standing in the criminal underworld), he felt that the simplest thing to do was to take the rap for the original burglary.

This is all to illustrate a philosophical point about the word "know" (and "knowledge" etc). A poll:

(ETA Note that the previous convictions don't count when I'm asking whether the legal system knew Bob had committed burglary... I meant to ask "...committed burglary on that day" or something similar. This ETA is before anyone but me has answered this, so all the results reflect this ETA)

This is a completely ridiculous hypothetical and the legal system wouldn't have acted that way

This is reasonably realistic, at least in terms of how the legal system acted

Ah, yes, they're good e.g.s. Unfortunately, they also involve breaking linguistics :) When you talk about a language having different words for different concepts, you're looking at good old fashioned etymologies and traditional semantics and so on. But when you talk about people meaning something different by the way they emphasise a word, you're into the field of pragmatics (which is all about why things mean what they mean in context), which is a relatively new concept[1]. Obviously when talking about philosophical and to some extent psychological aspects, this is perfectly justified. It's just a by-product that my head responds by dividing the two concepts and keeping them separate :)

[1] A case in point re pragmatics: 'relatively new concept' means something a bit different to a classicist like me from what it might mean to e.g. a modern linguist ;)

Yes exactly, thereabouts - this is very late by my internal timeline :)
