In discussing that horrid practice of 'writing', in the old times, usually done by one's scribes or 'secretaries', M. Davidson writes:

"Since slaves tend to be very unmotivated. Either the slave owner has to do it himself, in which case some of his own time is needed, or he has to employ a supervisor."

-- which would invite a regressus eis apeiron.

For who would supervise the supervisor?

H. P. Grice who retired in 1982 from academia, tried to learn a bit of computing, but found that the spell-checker would not allow 'sticky wicket' and gave up.
