This essay offers an overview of the reasons why tattoos are philosophically interesting. Considered here will be a partial survey of potential areas of philosophical interest with respect to tattoos, fortified by a little historical context. Claims about the ethical significance of tattoos and about the significance of tattoos for self-expression and as expressions of identity will be canvassed in the first two sections, as will questions about what they express or signify, how they might do so, and whose expression (...) we might take it to be. The final sections will address the contention that at least some tattoos are art and will raise various considerations about their closest analogs as well as their authorship. Although it will be argued that analogs can be found between tattoos and works recognized as art, it will also be maintained that tattoos raise unique aesthetic issues for consideration. (shrink)
