Journalism rapidly developed some professional norms; its own techniques; a variety of genres, of which investigative journalism would be one. Moreover it fed upon the increasing rationalism of intellectual discourse in the period and upon that scientific approach of finding truth from facts which was the Enlightenment’s greatest gift; in so doing it advanced the idea of objectivity, or at least impartiality. As with the great popular novelists, investigative journalists married rational observation with moral empathy and made exploitation and abuse an ever more likely topic of analysis, discussion and investigation.
