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.
With conventional placeholders, such as words, we can describe patterns for a large number of situations. On the other hand it is easy to fool yourself (and others) with words, since you can avoid to be specific. Any business meeting can confirm this.
When you draw something you are forced to be specific — and honest.
Our illustration of an “idea” from above is unconventional in the sense that it conveys specific original thoughts of what an idea is. It adds value to the words.
And that is the catch: The drawing must be unconventional to support the conventional words. We have to make sure not to use “words in disguise”. Take a common illustration for “idea” for example, which haunts flip charts all over the world: the lightbulb.
The lightbulb image works on a purely symbolic level, it only replaces the word “idea”. This image of a household item contains no original thought about what an idea is. While symbols like these work well as international replacements for words or icons to indicate a light switch for instance, they convey no nutritional value as illustrations — they are empty.
