She said: It hath reached me, O auspicious King, that when the Wazir Shimas asked the King's son, saying, "Which is the most excellent of the treasures of earth?" he answered, "The practice of kindness." So the Minister pursued, "Tell me of three several and different things, knowledge and judgment and wit, and of that which uniteth them."—"Knowledge cometh of learning, judgment of experience and wit of reflection, and they are all stablished and united in reason. Whoso combineth these three qualities attaineth perfection, and he who addeth thereto the piety and fear of the Lord is in the right course." Q "Take the case of a man of learning and wisdom, endowed with right judgment, luminous intelligence and a keen wit and excelling, and tell me can desire and lust change these his qualities?"—"Yes; for these two passions, when they enter into a man, alter his wisdom and understanding and judgment and wit, and he is like the Ossifrage[FN#106] which, for precaution against the hunters, abode in the upper air, of the excess of his subtlety; but, as he was thus, he saw a fowler set up his nets and when the toils were firmly staked down bait them with a bit of meat; which when he beheld, desire and lust thereof overcame him and he forgot that which he had seen of springes and of the sorry plight of all birds that fell into them. So he swooped down from the welkin and pouncing upon the piece of meat, was meshed in the same snare and could not win free. When the fowler came up and saw the Ossifrage taken in his toils he marvelled with exceeding marvel and said, 'I set up my nets, thinking to take therein pigeons and the like of small fowl; how came this Ossifrage to fall into it?'

As for the ignorant man, who hath neither knowledge nor judgment, while all things are obscure to him and desire and lust lord it over him, verily he doeth according to his desire and his lust and is of the number of those that perish; nor is there among men one in worse case than he." Q "When is knowledge profitable and when availeth reason to ward off the ill effects of desire and lust?"—"When their possessor useth them in quest of the goods of the next world, for reason and knowledge are altogether profitable; but it befitteth not their owner to expend them in the quest of the goods of this world, save in such measure as may be needful for gaining his livelihood and defending himself from its mischief; but to lay them out with a view to futurity."
