" Some may think it inadvisable to include the people as investigators in the search for their own meaningful thematics: that their intrusive influence (n.b., the “intrusion” of those who are most interested—or ought to be—in their own education) will “adulterate” the findings and thereby sacrifice the objectivity of the investigation. This view mistakenly presupposes that themes exist, in their original objective purity, outside people—as if themes were things. Actually, themes exist in people in their relations with the world, with reference to concrete facts. "
