“The mood of the group was generally gloomy, but George said we were going into a serious recession,” said Byron Wien, the chief investment strategist of Pequot Capital, a hedge fund.

Mr. Soros was one of only two people there who predicted the American economy was headed for a recession, he said.

Shortly after that luncheon Mr. Soros began meeting with hedge fund managers like John Paulson, who was early to predict a crisis in the housing market. He interrogated his portfolio managers and external hedge funds that manage his fund’s money, and he took on new positions to hedge where they might have gone wrong. His last-minute strategies contributed to a 32 percent return  or roughly $4 billion for the year.

The more Mr. Soros learned about the crisis, the more certain he became that he should rebroadcast his theories. In the book, Mr. Soros, a fierce critic of the Bush administration, faults regulators for allowing the buildup of the housing and mortgage bubbles. He envisions a time, not so distant, when the dollar is no longer the world’s main currency and people will have a harder time borrowing money.

Mr. Soros hopes his theories will finally win the respect he craves. But, ever the trader, he hedges his bets. “I may well be proven wrong,” he said. “I would say that I’m the boy who cried wolf three times.”

Many of the people Mr. Soros wants to influence may view him with skepticism, in part because of how he made his fortune. In 1992, his fund famously bet against the British pound and helped force the British government to devalue the currency. Five years later, he bet  correctly  that Thailand would be forced to devalue its currency, the baht. The resulting bitterness toward him among Thais was such that Mr. Soros canceled a trip to the country in 2001, fearing for his safety.

Asked if it bothers him that people accuse him of causing economic pain, his blue eyes dart around the room. “Yes, it does, actually yes,” he said.
