“…semiotic interpretations are not intended to answer the question of what forms mean. That might be a problem of iconology, or iconography, or psychology, or – of course – criticism. The issue which semiotics must address is not what forms mean, but rather how they mean the various things they mean the various things they do. In other terms, semiotics must study the expressive systems operating in each case: which traits of the form convey meaning, to which other traits they are opposed, how the relation between form and meaning originated, how meanings change, how interpretation is achieved, and so on.”
