alt Hacker NewsI think you are missing the point of that statement
It is a claim that swimming is a word that defines a context. It is an explicit statement that the question of whether a submarine can swim has nothing to do with the capability of the submarine.
If you are asking which pigeon hole we are putting something into, the answer is "The one we put it into". This is what make the question uninteresting.
If you are asking what is it about this pigeon hole that people value and does that align with the criteria that people use to decide categorisation. That very much is an interesting and complicated question.
The statement takes meaning-as-use as a given, sure, but I think the point of the statement is that people are arguing over an uninteresting question / taking meaningless positions about a meaningless issue, rather than "hey, words are moves in a language game!". I referenced two EWDs, which provide the original statements in context (though I can't find the widely-quoted wording anywhere: I thought I remembered it being in EWD1035, but apparently not). If you think my understanding of what Dijkstra meant was wrong, could you explain further, please?
