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 was thinking about this not long ago while reading in Petapixel an essay by a photographer named Scott Reither, “Long Form Study: Why Photographers Should Repeatedly Revisit A Scene.” In it, he described photographing one particular stretch of beach, over and over, throughout his career.
Of course that landscape has changed over time, and of course he’s had moments when he felt he’d captured the same territory so many times there was nothing left to see.
But there was always something more to see — maybe because of a change in Reither’s life, rather than in the physical environment.
