“Justification for infidelity and dishonesty in all their manifestations lies in the marginal cost economics of “just this once.”

“Like all strong people, she suffered always a measure of loneliness; she was a marginal outsider, a secret infidel of a certain sort.”

“Honesty doesn’t always pay, but dishonesty always costs.”

“That was how dishonesty and betrayal started, not in big lies but in small secrets.”

“And not only the pride of intellect, but the stupidity of intellect. And, above all, the dishonesty, yes, the dishonesty of intellect. Yes, indeed, the dishonesty and trickery of intellect.”

“Even if we could grow our way out of the crisis and delay the inevitable and painful reconciliation of virtual and real wealth, there is the question of whether this would be a wise thing to do. Marginal costs of additional growth in rich countries, such as global warming, biodiversity loss and roadways choked with cars, now likely exceed marginal benefits of a little extra consumption. The end result is that promoting further economic growth makes us poorer, not richer.”
