Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
Aesop's Fables. A new translation by Laura
Oxford University Press (World's Classics): Oxford, 2002.
THE MERCHANT AND THE RAVENS
Some merchants were making a journey when they happened to
meet a raven who was blind in one eye. The travellers halted
and one of them said that the sign given to them by the raven
meant that they should turn back home. Another member of the
company protested, 'But how can such a bird predict what is going
to happen to us, when he couldn't even predict the loss of his
own eye in time to take preventive measures?'
The same is true of people: someone who cannot manage his own affairs is
not qualified to give advice to his neighbours.
