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.
The best way to experience a restaurant, I have always felt, is by eating exactly what it wants to feed you. I do not want choices. I want the best thing. A restaurant might have five or ten best things, but it cannot have 45. There are many infuriating things about the world, but one of the more fixable is the sensation of acute regret from having ordered wrong. Why are there possibly wrong orders? Recently, I was at a fancy restaurant with great pastas and bad pizzas. So cut the pizzas!
A kitchen that focuses on its strengths turns out consistently excellent things, even if that results in fewer total things.
