The aftermath of the Covid restrictions, mental problems, being confronted with the influx of people with a different background and culture, the alienation of ourselves and of others, not being able to relate to other people; these can all cause deep feelings of loneliness. What is loneliness, as different from solitude? Whereas solitude is a chosen condition that refrains from social relations, loneliness suffers from the lack of these. The three essays in this book each explore a side of loneliness, strongly connected to the encounter with the other. South-African psychologist Wahbie Long lays out what kind of relationships to the outside world emerge from childhood experiences of playing and relating to others. He dives into the difficulty of not only encountering, but finding others. Long brings together a great many aspects that all contribute to the feeling of loneliness that characterizes the lives of migrants, asylum seekers, or refugees on the road. French philosopher Marie-José Mondzain uses the metaphor of architecture with its terms as threshold, doors, walls, windows, a bench in front of the frontal wall; elements that construct ‘home’, the architectural and emotional place where encounters can happen, where ‘strangers’ should be welcomed and trusted.
