The civilized world is engulfed in an epidemic of noise. Alerts coming to the mobile, the roar of transport, the sounds made by all kinds of equipment - all this is distracting and very unnerving, it does not allow you to concentrate or relax. The constant impact of noise on our nervous system causes stress, causes breakdowns and conflicts. Only in silence can we calm down, gather our thoughts and make the right decision, but we do not have the opportunity to retire, find a quiet corner, close ourselves from the outside world - cacophony overtakes everywhere. Norwegian writer and researcher Erling Kagge argues that perfect silence can be found even in the midst of the loudest noise, if you know how. In his essential book for every inhabitant of a big city, he answers three important questions: "What is silence?", "Where can I find it?" and "Why is it so important today?".
