My impression is that there was for Wittgenstein little or no region intermediate between a state of high and-concentrated seriousness and rather simple and sometimes almost crudely ‘low-brow’ interludes. I suspect that this, rather than the alleged ‘artificiality’ of the conversation at the High Table of Trinity, made the latter so distasteful to Wittgenstein. That conversation is the talk of men, all fairly eminent in their respective subjects, relaxing after a fairly tiring day’s work. It presupposes common traditions, going back to undergraduate days, and habitual ‘family’ jokes and allusions, and it moves in a sphere equally remote from high seriousness and from horseplay. A major prophet may be an excellent fellow, but he will hardly make an excellent Fellow. And, to pass from the general to the particular, one for whom philosophy is a way of life will find it difficult to associate on easy terms with those (like myself) for whom it is primarily a means of livelihood.
