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 cannot perceive for you. I can conceive for you and we can then in a sense hold a general agreement about quality of conception and we may all operate under it and that's what is known as a common agreement. But the area of perceiving as such is totally individual, there's no way that we carry it in that sense.
This is not an antisocial gesture; it is in fact a highly ethical one, since trying to get another person to see what and how you see has the potential to become a violation of the other's own autonomy:
There is nothing more unethical than having ambitions for someone else's mind.
