human actions to which a conventional meaning, or significance, is attributed. 
It has been used as the framework for anthropological investigations of 
cultures, their customs, etc., as, for example, in the work of Claude Lévi-
Strauss or in the interpretation of dreams and the structures of the unconscious 
in the works of Jacques Lacan.  
It is significant that, again, meaning is studied without reference to the 
consciousness of individual language speakers. Man is treated as essentially 
not just a language speaker but as a user and interpreter of signs, and the 
significance of these signs is determined without reference to any relation to 
the individual. A language, or sign-system, takes over the role of providing 
the framework of reason in which significance is given, but this framework 
transcends the individual. Such systems of codification regulate all human 
experience and activity and yet lie beyond the control of either individual or 
social groups. Indeed, since there is no meaning or understanding outside of a 
given sign-system, it is only from the meaning of the signs he “uses” that the 
individual comes to learn what it is that he means by his action, and hence 
what he thinks. This is why such views of language can readily be grafted 
onto Freud’s theory of the unconscious.  
Freud treated the realm of the mind as one that is as law-governed as is 
the natural world; nothing that a person does or says is haphazard or 
accidental, for everything can in principle be traced to causes that are 
somehow in the person’s mind, although many of these are not accessible to 
consciousness. Freud’s view of the human mind is thus very different from 
Descartes’s. For Freud, the part of the mind that is accessible to consciousness 
is but the tip of a large iceberg; the hidden remainder, which influences the 
conscious, is the unconscious. Thus, for instance, there are unconscious 
desires that can cause someone to do things that he cannot explain rationally
