There's magic to love... Millions of years ago we evolved three basic drives: the sex love, romantic love, and attachment to a long-term partner. These circuits are deeply embedded in the human brian. They're going to survive as long as our species survive on what Shakespeare called, this "mortal coil."
Hitler is a monster of wickedness, insatiable in his lust for blood and plunder. Not content with having all Europe under his heel, or else terrorized into various forms of abject submission, he must now carry his work of butchery and desolation among the vast multitudes of Russia and of Asia. The terrible military machine, which we and the rest of the civilized world so foolishly, so supinely, so insensately allowed the Nazi gangsters to build up year by year from almost nothing cannot stand idle lest it rust or fall to pieces. . . . So now this bloodthirsty guttersnipe must launch his mechanized armies upon new fields of slaughter, pillage and devastation.
Winston Churchill (1874 - 1965)
