We should note that all of these places of thermal extremes (Finnish saunas, Japanese hot baths, American beaches and mountains) have their opposites close at hand. There are possibly two reasons for having the extremes right next to each other.
The first is physiological: the availability of extremes ensures that we can move from one to the other to maintain a thermal balance.
The second might be termed aesthetic: the experience of each extreme is made more acute by contrast to the other.
Works of art which have great life often have intense contrast within: rough/smooth, solid/void, loud/silent, empty/full. It is the difference between opposites which gives birth to something. Contrast is what often gives other principles their degree of life – the intensity of the boundary, the markedness of the alternating repetition.
Contrast strengthens centers by making each a deeper entity of itself, and thereby giving deeper meaning to both. It is, at its simplest, what allows us to differentiate. But meaningless contrast remains meaningless. It is only when centers are actively, mutually, and meaningfully composed that it acts to deepen the whole.
[Andy Crouch] quotes the Japanese theologian Kosuke Koyama saying that “the speed of God” is three miles an hour because that was the speed at which Jesus moved through his world. So maybe, and I think this is one of the chief burdens of Andy’s book, what makes the most sense for us is to try whenever possible to move at the speed of God – and in that way refuse the offer of superpowers.
Of course, this dovetails with a lot of things people have been writing lately about slowness, but what I like about Andy’s book is that it specifies why we can find ourselves responding so warmly to the possibility of slowness. What happens when we seek superpowers, and especially super-speed, is the sacrifice of what I want to call our proper powers – the powers through the exercise of which we (heart-soul-mind-strength) flourish in love.
