signs...

Semiotics is the science of communication and sign systems, in short, of the ways people understand phenomena and organize them mentally, and of the ways in which they devise means for transmitting that understanding and for sharing it with others. Although natural and artificial languages are therefore central to semiotics, its field covers all non-verbal signalling and extends to domains whose communicative dimension is perceived only unconsciously or subliminally. Knowledge, meaning, intention and action are thus fundamental concepts in the semiotic investigation of phenomena.
