23.
The ungrateful man tortures and torments himself; he hates the gifts which he has accepted, because he must make a return for them, and he tries to belittle their value, but he really enlarges and exaggerates the injuries which he has received.
And what is more wretched than a man who forgets his benefits and clings to his injuries?
Wisdom, on the other hand, lends grace to every benefit, and of her own free will commends it to her own favour, and delights her soul by continued recollection thereof.
