The hermeneutic circle provides a straight forward answer to the question when to stop researching, and, as a corollary, when to stop interviewing. The premise for accepting this answer lies in recognizing that any scientific research must start with theory, as only a theoretical framework allows for the separation of realms for systematic inquiry. First, we have to define what we are interested in, then our theory will tell us what variables we have to look for and how we suppose they relate to the phenomenon in question. In other words, the hypotheses we formulate allow us to determine what is relevant to our inquiry. Once we have separated a realm for our inquiry, we can start the process of gathering data, where speech acts are considered part of the data to be collected. In addition to collection speech acts, we must contextualize this data with other information relevant to the speaker(s) so that we can reach an understanding of her lifeworld and situate her speech. This is achieved by going for and back between the specific and the general, the concrete speech act and the political, historical, psychological, and in general institutional context in which the speaker and the speech is embedded. This conceptions leads us to gather empirical data up to the point when each single new information "makes sense," i.e. it complements the logical structure of the lifeworld we are exploring. Each new interview must relate to and ultimately confirm what we already have found out, in a positive of negative way, and little by little we construct a contextualized understanding of the single speech act in question, which allows us to interpret each new piece information and locate it within the horizon of meanings that constitute the context or lifeworld of the speech and the speaker and the realm we have separated for our inquiry. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]
