A fleeting moment can become an eternity. From a past encounter everything may disappear in the dungeon of forgetfulness. A few furtive flashes or innocent twinkles can survive, though. Some immaterial details may remain marked in our memory, forever. A significant look, a salient colour or a unforeseen gesture may abide, indelibly engraved in our mind. ( "Girl in blue" )

Men wiser and more learned than I have discerned in history a plot, a rhythm, a predetermined pattern. These harmonies are concealed from me. I can see only one emergency following upon another as wave follows upon wave, only one great fact with respect to which, since it is unique, there can be no generalizations; only one safe rule for the historian: that he should recognize in the development of human destinies the play of the contingent and the unforeseen.

The unforeseen is the most beautiful gift life can give us. That is what we must think of multiplying in our domain. That is what should have been talked about in this assembly, and no one has said a word about it ...Art is inconceivable without risk, without inner sacrifice; freedom and boldness of imagination can be won only in the process of work, and it is there the unforeseen I spoke of a moment ago must intervene, and there no directives can help.

With a certain frustration I knew I spoke too soon, too urgently. I wanted to get out of the way the things I knew to say, wanted to say, the things I'd been thinking, all in the hope of moving into the unforeseen.

How do you calculate upon the unforeseen? It seems to be an art of recognizing the role of the unforeseen, of keeping your balance amid surprises, of collaborating with chance, of recognizing that there are some essential mysteries in the world and thereby a limit to calculation, to plan, to control.
