What is more natural in a democratic age than that we should begin to measure the stature of a work of art-especially of a painting-by how widely and how well it is reproduced?

It is only a short step from exaggerating what we can find in the world to exaggerating our power to remake the world. Expecting more novelty than there is, more greatness than there is, and more strangeness than there is, we imagine ourselves masters of a plastic universe. But a world we can shape to our will is a shapeless world.

The most refined skills of color printing, the intricate techniques of wide-angle photography, provide us pictures of trivia bigger and more real than life. We forget that we see trivia and notice only that the reproduction is so good. Man fulfils his dream and by photographic magic produces a precise image of the Grand Canyon. The result is not that he adores nature or beauty the more. Instead he adores his camera - and himself.

Celebrity-worship and hero-worship should not be confused. Yet we confuse them every day, and by doing so we come dangerously close to depriving ourselves of all real models. We lose sight of the men and women who do not simply seem great because they are famous but are famous because they are great. We come closer and closer to degrading all fame into notoriety.

The force of the advertising word and image dwarfs the power of other literature in the 20th century.

Not so many years ago there was no simpler or more intelligible notion than that of going on a journey. Travel -movement through space -provided the universal metaphor for change. One of the subtle confusions -perhaps one of the secret terrors -of modern life is that we have lost this refuge. No longer do we move through space as we once did.

The hero created himself; the celebrity is created by the media.
