Nudity is restricted in most societies, but some depiction of nudity may serve a recognized social function. Clothing also serves as a significant part of interpersonal communication, and the lack of clothing needs to have a social context. In Western societies, the three contexts that are easily recognized by a majority of individuals are art , pornography , and information or science. Any image not easily fitting into one of these categories may be misinterpreted, leading to disputes. At all times in human history, the human body has been one of the principal subjects for artists.
