How does the concept of semiotics differ from Blumer's Symbolic Interactionism, or Jung's idea of universal symbols? Semiotics appears to be an overarching concept...

okay, here's what I think:
1) semiotics is a method of analyzing language. one of its central tenets is that representation is a practice.
2) Blumer says that symbols are the basis of social life.
3) I don't pay any attention to Jung -- it's possibly a Freudian thing.

(how's that for reductio ad absurdum?)
