"There is convincing evidence that the search for solitude is not a luxury but a biological need. Just as humans posses a herding instinct that keeps us close to others most of the time, we also have a conflicting drive to seek out solitude. If the distance between ourselves and others becomes too great, we experience isolation and alienation, yet if the proximity to others becomes too close, we feel smothered and trapped."
"Who could deny that privacy is a jewel? It has always been the mark of privilege, the distinguishing feature of a truly urbane culture. Out of the cave, the tribal teepee, the pueblo, the community fortress, man emerged to build himself a house of his own with a shelter in it for himself and his diversions. Every age has seen it so. The poor might have to huddle together in cities for need's sake, and the frontiersman cling to his neighbors for the sake of protection. But in each civilization, as it advanced, those who could afford it chose the luxury of a withdrawing-place."
