“Eros, honoured without reservation and obeyed unconditionally, becomes a demon. And this is just how he claims to be honoured and obeyed. Divinely indifferent to our selfishness, he is also demoniacally rebellious to every claim of God or Man that would oppose him. Hence as the poet says:

People in love cannot be moved by kindness,
And opposition makes them feel like martyrs.

Martyrs is exactly right. Years ago when I wrote about medieval love-poetry and described its strange, half makebelieve, "religion of love", I was blind enough to treat this as an almost purely literary phenomenon. I know better now. Eros by his nature invites it. Of all loves he is, at his height, most god-like; therefore most prone to demand our worship. Of himself he always tends to turn "being in love" into a sort of religion.”
