“A melancholy lesson of advancing years is the realisation that you can't make old friends.”

“We owe a huge debt to Galileo for emancipating us all from the stupid belief in an Earth-centered or man-centered (let alone God-centered) system. He quite literally taught us our place and allowed us to go on to make extraordinary advances in knowledge.”

“Allow a friend to believe in a bogus prospectus or a false promise and you cease, after a short while, to be a friend at all.”

“What do you most value in your friends?Their continued existence.”

“Forget it. Never explain; never apologize. You can either write posthumously or you can't.”

“Suppose that a man leaps out of a burning building—as my dear friend and colleague Jeff Goldberg sat and said to my face over a table at La Tomate in Washington not two years ago—and lands on a bystander in the street below. Now, make the burning building be Europe, and the luckless man underneath be the Palestinian Arabs. Is this a historical injustice? Has the man below been made a victim, with infinite cause of complaint and indefinite justification for violent retaliation? My own reply would be a provisional 'no,' but only on these conditions. The man leaping from the burning building must still make such restitution as he can to the man who broke his fall, and must not pretend that he never even landed on him. And he must base his case on the singularity and uniqueness of the original leap. It can't, in other words, be 'leap, leap, leap' for four generations and more. The people underneath cannot be expected to tolerate leaping on this scale and of this duration, if you catch my drift. In Palestine, tread softly, for you tread on their dreams. And do not tell the Palestinians that they were never fallen upon and bruised in the first place. Do not shame yourself with the cheap lie that they were told by their leaders to run away. Also, stop saying that nobody knew how to cultivate oranges in Jaffa until the Jews showed them how. 'Making the desert bloom'—one of Yvonne's stock phrases—makes desert dwellers out of people who were the agricultural superiors of the Crusaders.”

“The friends of Galtieri, Saddam Hussein, Mullah Omar and Milosevic make unconvincing defenders of humanitarian values, and it can be seen that their inept and sometimes inane arguments lack either the principles or the seriousness that are required in such debates.”
