" In this way our perceptions of the world are constantly affirmed and buoyed up by others. I see people respond to the world in predictable ways and, to use Guenther’s phrase, it “supports the coherence of my own experience.” When human beings are isolated, they have no such support and thus no way to affirm the reality of their experience, of the world around them, even of their own existence, their own selves.
