2.Victor Turner, The Ritual Process: Structure and Anti-Structure, Lewis Henry Morgan Lectures, 1966 (Chicago: Aldine, 1969), 96, 132, 138-39, 177-78. The gardens and squares triggered a kind of spontaneous and direct social formation that anthropologist Victor Turner referred to "existential communitas." According to Turner, at times persons in societies may experience a moment of unification through a shared experience with strangers or acquaintances, a process he identified as "experiential communitas." The feeling of unity is so strong that the assembly or group identifies the experience as being shared and immediately seeks to organize its sense of itself as a group. This organizing impulse, he called "normative communitas." Turner’s communitas is then a "modality of social relationship," or a means of community formation, rather than a location. The ostensibly natural spaces of the parks and squares, liberated from the physical forms of the built environment, were fertile ground for the development of Turner’s spontaneous, organic process of communitas. Turner further argued that the sense of camaraderie can be so strong and its positive impact on social organization so great that the group seeks to reconstitute the sensation through repetitions of the experience, rites of passage, or rituals of communitas. Turner was primarily concerned with liminality, the secular and the sacred, social structure, and ritual as means of transcending social structures in societies, yet his concepts can be a helpful way of thinking about how people, who may have had a loose or even no connection to each other outside of the greenspace, might form bonds and coalesce into a recognizable group, by sharing the park space, an experience there (watching children at play, a romantic interlude, an hour of study), or interest in use of the space. Although the Luxembourg Garden had existed as a public greenspace for some time prior to 1865, the profusion of greenspace development throughout Paris during the Second Empire and the increase in a sense of communal ownership of parks, squares, and gardens throughout the city encouraged and even increased any existing sensibility among those for whom the Luxembourg Garden functioned as a neighborhood square as well as made that sensibility, and the desire to protect the garden, comprehensible to Parisians in other parts of the city.
