[ExI] knowledge at hand

[Lee Corbin]

How appealing is "knowledge at hand", anyway, i.e., being
able to remember the order of the eight planets and their
approximate distances?  Or to know off the top of your
head the first three rows of the periodic chart, to say nothing
of remembering history and dates?

Anyway, the following has many interesting implications not
directly related to the point I just made:

In the first place, Ebbinghaus has been forgotten, and the professional
educators won the battle, unfortunately, with the psychologists.
