I cannot recall the last time I experienced silence - the complete absence of sound.
Sure, there have been times that I would describe as “quiet,” even very quiet, but not silent. Even late at night when Harvard is asleep, I can hear the train engines idling a mile away.
The lack of silence in our lives is a health problem that also affects our mental capacity. This fact was first recognized over a century ago. Florence Nightingale, famous British nurse and activist, declared back in the 1800s that noise inflicted on patients was “cruel,” as it hindered their recoveries. Additionally, her American contemporary, writer Herman Melville wrote: “All profound things and emotions of things are preceded and attended by silence.”
