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.
I’ve written this before but I constantly need to remind myself of it, so, once again: A certain kind of work, lifestyle, mode of living — in and of itself — is protest. That is, work that is curious and rigorous is implicitly an antipode to didactic, shallow bombastity. It is inherently an archetype against bullshit. That to be committed to this work or life of rigor (be it rigor focused on “art” or, as they say in Japanese, sakuhin, or family or athleticism or whatever), and to share it with the world is to opt-out of being paralyzed by idiocy, and help others who may be paralyzed find a path back to whatever fecundity of life it is that they deserve.
