Searle argued that such institutional realities interact with each other in what he called "systematic relationships (e.g., governments, marriages, corporations, universities, armies, churches)"[REF] to create a multi-layered social reality.
For Searle, language was the key to the formation of social reality because "language is precisely designed to be a self-identifying category of institutional facts"; i.e., a system of publicly and widely accepted symbols which "persist through time independently of the urges and inclinations of the participants."[REF] .
