LOS ANGELES — As far as I know, Nebraska-born Theodore "Ted" Sorensen, who died last week at 82, disagreed with me only twice. He was right both times.

The disagreements were memorable, for in my mind they illuminated why the influence of John F. Kennedy's legendary right-hand man will remain enormous for decades. And why I am no Ted Sorensen.

The first occasion was at Princeton University when the then-visiting professor tendered this humble student a measure of advice on the art of writing.
