Roland Barthes was a seminal thinker in the field of semiotics, which is the study of signs and sign systems. He viewed signs as having both a literal meaning, known as the signified, as well as an ideological meaning, or connotation, that is influenced by cultural and social contexts. Myths, which are second-order sign systems, take existing signs and imbue them with new ideological meanings that serve to naturalize and perpetuate the status quo. However, not all sign systems uphold dominant values, as some have the power to temporarily subvert mainstream perspectives before potentially being co-opted.
