That's a famous quote and age might have mellowed him. But he was not like that at all in person with his students. He did insist that one be precise with ones words.
The origin of the quote may have more to do with cultural differences between the Dutch and Americans.
I’d want to see an example of Dijkstra’s “arrogance” that wasn’t justified.
The “truths that might hurt” essay is a great example. Yeah, the truth hurts for many people. People don’t like being called out on their folly, particularly if it’s something they don’t personally control. That Durant make it “arrogant” to point it out.
Also, Alan Kaye is overrated. Object orientation is one of those painful truths.
That's a great point which never occurred to me about Dijkstra, even though I knew where he came from. My father in law used to like this joke: "He was Dutch and behaved as such."
