This one from Keynes: "It is necessarily part of the business of a banker to maintain appearances, and to profess a conventional respectability, which is more than human. Life-long practices of this kind make them the most romantic and the least realistic of men. It is so much their stock-in-trade that their position should not be questioned, that they do not even question it themselves until it is too late. Like the honest citizens they are, they feel a proper indignation at the perils of the wicked world in which they live, — when the perils mature; but they do not foresee them." From Essays in Persuasion 1931
