Language as a Way of Knowing
Whole section of the brain devoted to language and the brain is where we understand knowledge Similar to Saussure Views: Signifier doesn’t mean anything by itself so the brain automatically associates it with its meaning Saussare “All signs arbitrary, and all signs have only arbitrarily ascribed or assigned meanings. Each society, through its language, gives meaning to its signs through combining sound-images (signifiers) with concepts (what is signified).”
