A topic is essentially a*sub)ect for discussion. The Greek word topos from which**topic^’ is derived literally means a place. Its literal meaning is retained in suchEnglish words as “topography” and “topology,” which signify the study ofphysical or geometrical places. The conception of a topic as a subject for discus’-sion is a metaphorical extension of this root meaning. A topic is a logical place; itis a place where minds meet to consider some common problem or theme.The minds may agree or disagree; they may argue the matter from differentpoints of view; they may contribute to the discussion in a variety of ways — byoffering examples, by proposing definitions or hypotheses, by stating analyses orarguments, by debating what has already been said, or by advancing a new view.But whatever form each contribution takes, it must be relevant, though it neednot be relevant in the same way or to the same degree. The various contributionsare relevant to each other through their relevance to the common theme orproblem, and this gives unity to the variety of things being said.A topic, then, is a place where minds meet through being relevant to a commonsubject of discussion. It is a place at which an intelligible exchange of thought,insight, or opinion can occur.
