“Is that your way, Denis, of judgin' colors?”

“Shut your eyes, I say, till I give you ocular demonstration of the differ atween these two respectable colors.”

“Well, they're shut.”

“An' keep them so. Now, what differ do you see atween them?”

“The sorra taste, man alive; I never seen anything in my whole life so clearly of a color as they are both this minute.”

“Don't you see now, Phadrick, that there's not the smallest taste o' differ in them, an' that's accordin' to Euclid.”

“Sure enough, I see the divil a taste o' differ atween the two.”

“Well, Phadrick, that's the point settled. There's no discrimination at all atween black an' white. They're both of the same color—so long as you keep your eyes shut.”

“But if a man happens to open his eyes, Dinny?”

“He has no right to open them, Phadrick, if he wants to prove the truth of a thing. I should have said probe—but it does not significate.”
