We confuse data with information, information with knowledge, and knowledge with wisdom. This tendency worried Schopenhauer. Everywhere he saw people scrambling for information, mistaking it for insight. “It does not occur to them,” he wrote, “that information is merely a means toward insight and possesses little or no value in itself.” I’d go a step further. This excess of data—noise, really—has negative value and diminishes the possibility of insight. Distracted by the noise, we don’t hear the music.
