"— You are a delusion, said roundly John Eglinton to Stephen. You have brought us all this way to show us a French triangle. Do you believe your own theory?
— No, Stephen said promptly.
— Are you going to write it? Mr Best asked. You ought to make it a dialogue, don't you know, like the Platonic dialogues Wilde wrote.
John Eclecticon doubly smiled.
— Well, in that case, he said, I don't see why you should expect payment for it since you don't believe it yourself. Dowden believes there is some mystery in Hamlet but will say no more." (U9.1064)

Note: this is not John Eglinton.
