The Cognitive Style of PowerPoint
An Essay by Edward TufteIn corporate and government bureaucracies, the standard method for making a presentation is to talk about a list of points organized onto slides projected up on the wall. For many years, overhead projectors lit up transparencies, and slide projectors showed high-resolution 35mm slides. Now "slideware" computer programs for presentations are nearly everywhere. Early in the 21st century, several hundred million copies of Microsoft PowerPoint were turning out trillions of slides each year.
Alas, slideware often reduces the analytical quality of presentations. In particular, the popular PowerPoint templates (ready-made designs) usually weaken verbal and spatial reasoning, and almost always corrupt statistical analysis. What is the problem with PowerPoint? And how can we improve our presentations?
The Japanese Perspective
Generally speaking, the Western perception of art has its roots in Greece. For a long time its goal was perfection, which is particularly noticeable in Greek sculpture. This was in keeping with Western scientific thinking; there are no painters like Andrea Mantegna in the East. I am tempted to call such art ‘the art of even numbers’.
In contrast to this, what the Japanese eye sought was the beauty of imperfection, which I would call ‘the art of odd numbers’. No other country has pursued the art of imperfection as eagerly as Japan.
The true meaning of tea
There is no true deformation that does not follow the laws of necessity. In later years, when deformation came to be consciously created, when the rejection of perfection became a matter of deliberate manipulation, the true meaning of tea began to be lost.
To put it in somewhat contradictory terms, true tea existed only before the advent of the tea ceremony. After the coming of tea, when deformation came to be consciously sought, common everyday beauty disappeared and unnatural manipulation began.
One receives with an empty hand
Intuition means to see immediately, directly.
Considered as a form of activity, the seeing eye and the seen object are one, not two. One is embedded in the other. People who know with the intellect before seeing with the eyes cannot be said to be truly seeing.
With intuition, time is not a factor. It takes place immediately, so there is no hesitation. It is instantaneous. Since there is no hesitation, intuition doesn’t harbour doubt. It is accompanied by conviction. Seeing and believing are close brothers.
Only when it has ceased to be a pattern
Here I would like to append three lines in praise of muji:
A pattern that is not a pattern is a true pattern.
Create patterns until they are no longer patterns.
The true pattern is a patternless pattern.When creating a pattern, one’s heart must also be muji. A pattern must be followed through until it is no longer a pattern. It is a true pattern only when it has ceased to be a pattern.
