When asked by a young man if he should seek to marry, Socrates answered him:
“By all means marry: if you get a good wife, you will be happy; if you get a bad one, you will become a philosopher.”
He is, of course, correct.
And as a bonus, here is Professor John Robson on the Magna Carta – starting with the story of Alfred the Great:
The Oracle of Delphi called Socrates 'the wisest man' because he said:
"I know I know nothing!"
Of course, he only knew this because his wife, Xanthippe, told him so.
Every day!
