Waiting for Diaspar

It was the custom of the city's artists - and everyone in Diaspar was an artist at some time or another - to display their current production along side of the moving ways, so that the passers-by could admire their work. In this manner, it was usually only a few days before the entire population had critically examined any noteworthy creation, and also expressed views upon it. The resulting verdict, recorded automatically by opinion-sampling devices which no one had ever been able to suborn or deceive - and there had been enough attempts - decided the fate of the masterpiece. If there was a sufficiently affirmative vote, its matrix would go into the memory of the city so that anyone who wished, at any future date, could possess a reproduction indistinguishable from the original.
