I agree that the answers to these questions depend on definitions
I think he meant that those questions depend ONLY on definitions.
As in, there’s a lot of interesting real world knowledge that goes in getting a submarine to propel itself, but that now we know that, have, people asking “can a submarine swim” is only interesting in deciding “should the English word ‘swim’ apply to the motion of a submarine, which is somewhat like the motion of swimming, but not entirely”. That example sounds stupid, but people waste a lot of time on the similar case of “think” instead of “swim”.

Ok, that’s a good point; inserting the word “only” in there does make a huge difference.
I also agree with BerryPick6 on this sub-thread.
