"Pollock tells us all we need to know about money and banking, risk and uncertainty, debt and temptation, and science and economics. He delights as he instructs.”―James Grant, founder and editor, Grant’s Interest Rate Observer Finance and Philosophy provides a concise and witty account of how bankers and financial regulators think, of the alleged causes of the cycles of booms and busts, of the implicit and often un-thought-out assumptions shaping retirement finance, fiat money, corporate governance. Pollock deftly shows how poorly bankers have measured the risk their banks have been exposed to. With candor and clarity, he uncovers the persistent and unavoidable uncertainty inherent in the business of banking. We learn that a banker’s confidence in his ability to measure banking risk accurately is the lure which has repeatedly led to bank failures. Pollock has a modest and compelling suggestion: Acknowledge the unavoidability of ignorance with respect to financial risk, and, in the light of this ignorance of the future, act moderately.
