It was a German physicist, Gustav Techner(1801-1887), who first realized that we do not feel a sensation——for example, a pinprick——until it reaches a certain intensity, that is, until it passes a perception threshold. A great many phenomena follow the same law. They are not actually “phenomena.” They are data until they reach a certain intensity, and pass the perception threshold.——《Management Challenges for the 21st Century》Chapter 4.
