Bob cited Sir Francis Bacon - on Studies - a quotation remembered from childhood. I did learn something at school. But until I looked up the essay in my own little book from 54 years ago, c1954!!! (first published 1903) OUP, edited W. Peacock, I was unable to find the quote online. The whole essay is here.
STUDIES serve for delight, for ornament, and for ability.Worth the read - just for the rhetoric.
Their chief use for delight, is in privateness and retiring;
for ornament, is in discourse;
and for ability, is in the judgment, and disposition of business.
For expert men can execute, and perhaps judge of particulars, one by one; but the general counsels, and the plots and marshalling of affairs, come best, from those that are learnèd.
To spend too much time in studies is sloth;
to use them too much for ornament, is affectation;
to make judgment wholly by their rules, is the humor of a scholar.
