" Love has many faces. And if you love, you have to be strong enough to look upon all of them. The essence of philia is, I think, far harsher, far crueller, than we care to admit. There is one thing without which philia cannot exist; and this is not a matter of feeling but of the will. Philia—the love appropriate to your pack—is the will to do something for those who are of your pack, even though you desperately don’t want to do it, even though it horrifies and sickens you, and even though you may ultimately have to pay a very high price for it, perhaps heavier than you can bear. You do this because that is what is best for them. You do this because you must. You may never have to do this. But you must always be ready to do it. Love is sometimes sickening. Love can damn you for all eternity. Love will take you to hell. But if you are lucky, if you are very lucky, it will bring you back again. "
