"I object, because in nine cases out of ten they're got by trading on another person's ignorance."
"Of course they are. Why not? If he's ignorant, it's only fair he should pay for his ignorance; and if I'm an expert, it's fair I should get an expert's profits. It's all a question of buying and selling. He can't sell what he hasn't got; and I can't sell what I haven't got. Supposing I've got knowledge that he hasn't—if I can't make a profit out of that, what can I make a profit out of?"
"I can't say. My own experience of the business was unfortunate. It struck me, if you remember, that some of your profits meant uncommonly sharp practice."
"Talk of ignorance! Really, for a clever fellow, Keith, you talk a deal of folly. There's sharp practice in every trade—in your own trade, if it comes to that. Supposing you write a silly book, and some of your friends boom it high and low, and the Public buys it for a work of genius—well—aren't you making a profit out of other people's ignorance? Of course you are."
"I haven't made much profit that way—yet."
"Because you're unbusiness-like. Well. I'm perfectly willing to believe your objections are conscientious. But look at it another way. I'm a God-fearing, religious-minded man" (unconsciously he caressed his soft hat, the hat of a Methodist parson, as he spoke), "is it likely I'd continue in any business I couldn't reconcile to my conscience?"
"I've no doubt you've reconciled it to your conscience. That's hardly a reason why I should reconcile it to mine."
"That means that you'll let me be ruined for want of a little advice which I'd 'ave paid you well for?"
"If my advice is all you want, you can have it any day for nothing."
"Wot you get for nothing is worth just about wot you get it for. No. Mine was a fair business proposal, and either you come into it or you stay out."
