Semiotics (from the Greek root sema [sign]) proposes to be a science of signs and symbols and how they function in both linguistic (human and culture) and nonlinguistic (natural and artificial) systems of communication. In both instances the science has ethical dimensions. With regard to language and culture, some traditions of semiotics seek to expose what they argue are illegitimate uses of signs and symbols. With regard to nature and machines, questions arise about the legitimacy of conceiving interactions between noncultural phenomena in the same terms as cultural phenomena.
