Yet we see that in similar circumstances one man will say of the other, "O, he was so good. I went to him at lunch-time and he was so kind as to ask me to have lunch with him." This is a man's feast; the other was a dog's feast. This is where man should be different from an animal. An animal will not recognize his mother, or father, or his birthplace, but man will. After he has grown up he will consider, "My mother took care of me when I was an infant and was so kind to me; and now she is aged, so I will do everything in my power for her." He dwells on all the respect he can show her, and how worthy she is of it. At once he shows himself to be man; the animal does not act in this way. Hence, in the case where a man does the same as an animal, and does not care for those who did all they could for him in his youth, he shows his lack of humanity. Forgetfulness and lack of appreciation of the care bestowed during childhood are characteristic of the animal.
