Now let’s suppose our thinker’s focus is just a bit lower. His thought-stream might start out in the same way—might extend, say, through “Schwartz’s dinner party last fall was kind of fun,” and pause there for awhile—various aspects of the party come to mind; and then, next thing he knows, the thinker might find himself contemplating Long Island Sound as he crossed it on a ferry years ago, seated on the stern deck, admiring the glitter of the soft green water on a bright, hazy summer afternoon. That summer afternoon has no obvious connection of any kind with the Schwartz’s dinner…but, for some reason or other, it just comes to mind.
