Memes are omnipresent online and have become an increasingly important facet of not only the field of digital rhetorics, but of pop culture in general. What appear to be little more than funny images with a punchline, however, are actually powerful vehicles for culture and ideology. In Memetic Rhetorics, Erika M. Sparby untangles some of the complexities of memes by determining how memes function rhetorically in our society, examining rhetorical ethical considerations, highlighting how memes fuel cultural ideology, and finding ways to reveal and reject uncritical memetic behaviors. Through this careful look at the rhetoric and ethics of memes, Memetic Rhetorics demonstrates that memes manipulate and reflect culture and ideology and thus shape our identities and our world.
