love does not concern the king. On the contrary, the man who puts the apple to his mouth and eats it in the king’s presence loves the apple itself and his own soul rather than the king. It sometimes happens that the king is not pleased with that love which nourishes the instinctual soul; in fact, he detests it. Moreover, the pleasure that the apple gives is very limited and passes quickly. After the apple is eaten it is gone, only regret remains.
As for the second love, it is for the royal favour that is demonstrated by means of the apple. One who holds the apple precious as if it were the sample and embodiment of a royal favour shows that he loves his king. Moreover, the pleasure in that fruit, which is a sort of container for the favour, is such that it is far greater than the pleasure obtained from a thousand apples. This pleasure, then, is the essence of thankfulness. This love is a respectful love for the king.
In exactly the same way, if all bounties and fruits are loved for themselves, if they are thoughtlessly delighted in only for the material pleasures that they yield, that love is merely love of self. Also, those pleasures are transient and bring pain. But, if they are loved as favours proceeding from Almighty God’s mercy and as fruits of His munificence, and if pleasure is obtained from them with good appetite by appreciating the degree of kindness in that munificence and favour, then it has both the meaning of gratitude and is a pain-free pleasure.
