The evolutionary introduction of language in the human species has given us a unique ability to cooperate in large and highly adaptable social groups. Our capacity for language allows us to live according to imagined cultural orders, such as the legal and economic frameworks that govern civic life. These frameworks exist in our shared imagination and are sustained through communication networks, linking the subjective consciousness of many individuals. These shared beliefs shape our societies and our world, and form the basis of study of most of the humanities. History has shown us the great consequences and opportunities of our shared beliefs, which determine our cultural values and prejudices. By observing and understanding language structure, we learn more about ourselves and the world which we create. We also learn about the mechanisms which will be required to create the kind of world we would like to live in.
