I’ve been reading Chesterton’s Orthodoxy. I’ll review it later, as if its reputation depended on me to any extent. But here’s a quote:

It is one of the hundred answers to the fugitive perversion of modern “force” that the promptest and boldest agencies are also the most fragile and full of sensibility. The swiftest things are the softest things. A bird is active, because a bird is soft. A stone is helpless, because a stone is hard. The stone must by its own nature go downwards, because hardness is weakness. The bird can of its nature go upwards, because fragility is force. In perfect force there is a kind of frivolity, an airiness that can maintain itself in the air. Modern investigators of miraculous history have solemnly admitted that a characteristic of the great saints is their power of “levitation.” They might go further; a characteristic of the great saints is their power of levity. Angels can fly because they can take themselves lightly.
