????上周，筆者撰文提出，在世界經濟論壇（the World Economic Forum）年會的討論中，應該包容發散性思維，以及有別于多數派的不同聲音。當我靜下來，思考過去五天在達沃斯的經歷時，我覺得我們需要進一步擴大我們的隊伍——將一些“希望的積極倡導者們”也請到我們中間來。

????丘吉爾曾經說過：“我寧愿做一個樂觀主義者。因為做別的人也沒什么用?！惫P者認為，如果世界經濟論壇仍希望解決世界所面臨的問題，而不只是提出問題，那就應該把這句至理名言作為論壇的口號。

????我記得年輕時，曾與一位樂觀了一輩子的世交進行過一次對話。他告訴我，半空的杯子，應該總被視為半滿，甚至在某些情況下，三分之一滿的杯子也應該被視為半滿。他說：“即使杯子里只有一滴水，我也視它為半滿?！蔽页爸S他積極的態度，問道：“如果沒有杯子呢？”他這樣回答我，“總會有杯子的。”他的話讓我啞口無言，若有所悟。

????本周末，我開始回顧我在世界經濟論壇上的記錄，并通過互聯網研究世界的情緒和觀點。這時，我想起了朋友的話。我不得不承認，看到唱哀調的推文數量時，我大吃一驚。如果有“舉手表決”調查，悲觀論者的數量可能會超過達沃斯論壇上持樂觀觀點者的數量。但是，無論如何，這種壓倒一切的悲觀主義似乎沒有任何意義。

????在達沃斯論壇上，我每到一處都會看到行動和承諾的影子。我首次見證了與會者在對待最強硬和最具諷刺意味的觀點時，所表現出來的膽量。一次次的會議都在討論重新界定資本主義以及包容性的需求，而比爾?蓋茨卻承諾出資7.5億美元抗擊艾滋病。德國總理安吉拉?默克爾仍在努力激勵和恢復各界對歐元區這個半成品的信心，而經濟學家、從業者、學術界和商界領袖則齊聚一堂，跨越行業界限，提出切實可行的解決方法。

????此外，在創造就業方面，與會者也表現出同樣的決心。例如，在跨行業CEO專題會議上，大多數公司都計劃擴大招聘規模，同時打造新的人才庫。與會者表現出勇于承擔責任的態度，共同面對困難，并展現出解決問題的共同決心。

????另外，我還注意到，在達沃斯論壇上，另外一種不同的變革正在醞釀之中。因為缺乏更好的表述，我們暫且稱它為“信任的復蘇”。商界與政界領導人強調，在金融危機之后必須重建公眾的信任。波蘭總統布羅尼斯瓦夫?科莫羅夫斯基著重強調：“這場危機不僅是一場經濟危機，更是一場信任危機。我們要做的，就是恢復信任?！边@些言論都是令人鼓舞的跡象，它們都表明，全球越來越多的領導人勇于擔當，解決我們目前面臨的問題。因此，以“道德困境”和“英明領導力”等為主題的分會與會者絡繹不絕也就不足為奇了。

????Last week, I wrote about the need to include divergent and contrarian views in the conversations taking place at the World Economic Forum annual meeting. As I sit back and reflect on my five days at Davos, I feel that we need to extend the circle further -- to include some "protagonists of hope."

????Churchill once famously said, "I am an optimist. It does not seem too much use being anything else." I believe that these wise words may need to become the rallying call of the WEF, too, if it is to continue contributing answers to the challenges facing the world and not just raising questions.

????I remember a conversation I had as a young man with an eternally optimistic family friend who told me that half-empty cups should always be seen as half full and oftentimes even one-third full. "Even if there is only a single drop of liquid in the cup, I consider it to be half full", he said. "But what if there is no cup?" I asked, mocking his positive outlook. "There is always a cup," he replied, leaving me speechless and much the wiser that day.

????I was reminded of his words as I sat back this weekend to pour over my WEF notes and study the mood and opinions of the world on the web. I must confess I was taken aback, for example, by the number of tweets that talked of gloom and doom. If there were to be a "show of hands" poll, the prophets of doom would have outnumbered the hopeful ones in Davos, too. But, somehow, the overbearing cynicism didn't seem to add up.

????Everywhere I looked while at Davos, there were indicators of action and commitment. For the first time at the conference, I noticed a boldness in how people approached even the toughest and most sacred notions. As session after session attempted to redefine capitalism and the need to be inclusive, Bill Gates pledged $750 million to fight AIDS. And as German Chancellor Angela Merkel worked to shore up and restore confidence on the work-in-progress that is the Eurozone, economists, practitioners, academics, and business leaders huddled across lines to offer pragmatic solutions.

????I saw a similar resolve on the challenge of job creation. For example, in a cross-industry CEO meeting on the topic, it was clear to me that most companies both planned to hire more people and build new sources of talent. There was a sense of urgent commitment in the room, a collective ownership of the problem and a collective resolve to solve it.

????I also noticed a very different kind of revolution take shape in Davos. For want of a better phrase, let's call it a resurgence of trust. Business and political leaders from all walks of life emphasized the need for rebuilding public trust following the financial crisis. Polish President Bronislaw Komorowski underlined it emphatically: "The crisis is not only an economic crisis, but also a crisis of trust. What we shall do is to restore trust." Expressions like these were signs of an encouraging and growing acceptance of responsibility among global leaders for tackling the problems we face. It was not surprising to see sessions on themes like "ethical dilemmas" and "wise leadership" overflowing with attendees.
