" We see the same colours, Mr Essex,” Mr Coffey relented as Theophilus began to unfasten the waist of his trousers, “but if you might count their shades in the hundreds, whereas I might define a paltry dozen, I do not believe we see the same number at all.”

Theophilus almost found himself clucking his tongue, as he knew his father to do when faced with an equation he struggled to solve, and neatly folded his breeches once drawn off, setting them aside. “You might still distinguish between their shades by sight,” he argued, beginning to draw on his Sunday breeches. “To say that you cannot see something simply because you do not know its name would be absurd. Eve and Adam would not have seen the Tree of Knowledge if the Almighty had not told them its name.”

“I know you are being sardonic with me, Mr Essex,” Mr Coffey said, “but I do believe there to be some truth in that. "
