During the time I was teaching at Harvard as an Instructor in Philosophy and General Education, the wunderkind Saul Kripke showed up as a Freshman at Harvard, having already had an article accepted for publication in The Journal of Symbolic Logic, the leading professional journal in the field. Saul was a piece of work but there was no denying his brilliance, and Quine treated him as an equal, in what I have always considered a manifestation of real academic class.
In 1960, Quine published what was to become perhaps his most influential book, Word and Object. Saul read it, and made an appointment with Quine to talk about it. When the day of the appointment arrived, Saul stood Quine up. Now, the morés of the Academy have changed in the past half century, and students these days [if I may speak with a crustiness befitting my age] no longer exhibit an appropriate respect for their elders and betters. But in those days, it was unheard of for a student -- any student -- to make an appointment with a professor and then simply not show up. Saul came slouching around a while later with some excuse, and Quine agreed to another appointment, at Eliot House, where Quine had an affiliation. Marshal Cohen, then a young Assistant Professor, told me that he walked by just as Saul and Quine were saying goodby, and swears that he heard Quine mumbling to himself, "Maybe I am all wrong. Maybe I have got it all wrong." (Robert Paul Wolff, A Life in The Academy, p. 81-82)
