In 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?
Let us take a look at how one of these scholars or critics goes about his work. Let’s say he is going to write a commentary on a particular painting. If he is not a man of intuition, certain features will characterize his approach. First he will try to place the painting genealogically, or he will try to define the painting by assigning it to a particular school. He feels uneasy unless he succeeds in doing this.
But more than anything, he is extremely wordy. He seems incapable of speaking of beauty without innumerable layers of adjectives.
One can study an object and note its features, but that only touches the surface. A knowledge of an artwork’s properties does not lead to an understanding of its essence.
