Victor Turner combined Arnold van Gennep's model of the structure of initiation rites, and Gluckman's functionalist emphasis on the ritualization of social conflict to maintain social equilibrium, with a more structural model of symbols in ritual. Running counter to this emphasis on structured symbolic oppositions within a ritual was his exploration of the liminal phase of rites of passage, a phase in which "anti-structure" appears. In this phase, opposed states such as birth and death may be encompassed by a single act, object or phrase. The dynamic nature of symbols experienced in ritual provides a compelling personal experience; ritual is a "mechanism that periodically converts the obligatory into the desirable".
