A "sound" banker...

"" As Mr. Keynes has fairly and bitterly written (in his Essay in Persuasion, page 176) .. "A “sound” banker is not one who foresees danger and avoids it, but one who, when he is ruined, is ruined in a conventional and orthodox way along with his fellows, so that no one can really blame him".""
