The Crock of Gold by James Stephens

To the lonely house in the pine wood people sometimes came for advice on subjects too recondite for even those extremes of elucidation, the parish priest and the tavern. These people were always well received, and their perplexities were attended to instantly, for the Philosophers liked being wise and they were not ashamed to put their learning to the proof, nor were they, as so many wise people are, fearful lest they should become poor or less respected by giving away their knowledge. These were favourite maxims with them:

You must be fit to give before you can be fit to receive.
