Chesterton says that loving and fighting go together. “To love a thing without wishing to fight for it is not love at all; it is lust.”
“He knows that loving the world is the same thing as fighting the world” (Appreciation and Criticism of the Works of Charles Dickens).
Chesterton rejects the silliness of today’s philosophers who want to separate loving and fighting, putting them into separate camps. This is well represented by the glib placard of the sixties, urging us to make love, not war. This false juxtaposition is trying to hide the fact that it is always both.
Either you make love indiscriminately, and make war on the resultant offspring, or you make love to one woman for life and fight to protect her and the children you have fathered. If you determine that it is too militant to fight in the latter way, then the love you have chosen in the former way is simply lust.
And we can see that this is how it is unfolding in the West. Lunatic wars and lunatic lusts go together. So do chivalric wars and chivalric romances. The pacifist who doesn’t want to fight the dragon for the sake of the lady is actually in the process of becoming a dragon himself. This reality is sometimes obscured by the missing nostril flame and hidden claws, but there is a ready explanation. Pacifists are just passive aggressive dragons.
