On loving one's enemies

Enjoyable reading:

And there is a second commandment, which seems to me even more incomprehensible and arouses still stronger opposition in me. It is 'Love thine enemies'. If I think it over, however, I see that I am wrong in treating it as a greater imposition. At the bottom is the same thing [as the commandment 'Thou shalt love thy neighbour as thyself']. (1)

(1) A great imaginative writer may permit himself to give expression -jokingly, at all events- to psychological truths that are severely proscribed. Thus Heine confesses: 'Mine is a most peaceable disposition. My wishes are: a humble cottage with a thatched roof, but a good bed, good food, the freshest milk and butter, flowers before my window, and a few fine trees before my door; and if God wants to make my happiness complete, he will grant me the joy of seeing some six or seven of my enemies hanging from those trees. Before their death I shall, moved in my heart, forgive them all the wrong they did to me in their lifetime. One must, it is true, forgive one's enemies- but not before they have been hanged.' ](Gedanken und Einfälle [Section I].)

Once again Freud is his Civilization and its discontents.
