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.
When I was a product designer, people would ask what I did for a living, and sometimes I’d answer “I draw pictures of websites.”
Sure, I could just say “I design websites.” That’s true. The end result of my work is (hopefully) that a website looks better, works better, or results in better outcomes.
But most of my day isn’t spent looking at the website, or working on the code of the website, or manipulating the website directly in some way. It’s spent in Figma or Sketch, drawing pictures of how I think the website should look and work.
Through some kind of alchemy, the pictures I draw have an impact on the finished website. But they’re not all the same.
