This illustrates the animal nature. Man's selfishness shows itself in wanting to get the better of his fellow-man. If we developed humanity we should do differently. We should be satisfied with a slice of bread if there were another in need, but as it is, it happens that even when we are fed ourselves, we do not wish anyone else to share the food. The human heart can only be really satisfied by knowing that the other person is happy. True pleasure lies in the sharing of joy with another. From the day that we realize this we begin to act as human beings; hitherto we have not done so even though we have human forms.
