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.
Maybe the internet is due for a wave of things that don’t scale at all. In that light, I’ve been fascinated by ‘Morioka Shoten’ in Tokyo - a bookshop that sells only one book at a time. This is retail as anti-logistics - as a reaction against the firehose, and the infinite replication of Amazon. Before the internet that would only work in a very dense city, but, again, the internet is the densest city on earth, so how far do we scale the unscalable?
