George Ricker Berry says the term "higher criticism", which is sometimes used as an alternate name for historical criticism, was first used by Eichhorn in his three-volume work "Einleitung ins Alte Testament" (Introduction to the Old Testament) published between 1780 and 1783. The term was originally used to differentiate higher criticism, the term for historical criticism, from lower, which was the term commonly used for textual criticism at the time. The importance of textual criticism means that the term 'lower criticism' is no longer used much in twenty-first century studies.
