在一篇2014年蒙格接受華爾街日報的訪談中，看到他如何談葛拉漢，內容用字遣詞之直白，不難看出他當年應該是花了很大力氣，才將巴菲特從葛拉漢的投資系統拉到今日的波克夏（Berkshire Hathaway, BRK.A-US）投資學。
在併購See’s Candy的交易中，巴菲特一度因為對方出價太貴而想放棄，但在蒙格的勸說之下，勉為其難的出了2,500萬，但仍低於對方出的3,000萬，最後所幸對方讓步了，現在See’s Candy所帶來的報酬豈止百倍，他差一點為了500萬損失了價值百億的機會。
I don’t love Ben Graham and his ideas the way Warren does. You have to understand, to Warren — who discovered him at such a young age and then went to work for him — Ben Graham’s insights changed his whole life, and he spent much of his early years worshiping the master at close range. But I have to say, Ben Graham had a lot to learn as an investor. His ideas of how to value companies were all shaped by how the Great Crash and the Depression almost destroyed him, and he was always a little afraid of what the market can do. It left him with an aftermath of fear for the rest of his life, and all his methods were designed to keep that at bay.
I think Ben Graham wasn’t nearly as good an investor as Warren Buffett is or even as good as I am. Buying those cheap, cigar-butt stocks [companies with limited potential growth selling at a fraction of what they would be worth in a takeover or liquidation] was a snare and a delusion, and it would never work with the kinds of sums of money we have. You can’t do it with billions of dollars or even many millions of dollars. But he was a very good writer and a very good teacher and a brilliant man, one of the only intellectuals – probably the only intellectual — in the investing business at the time.
