His
The Semantics of Biblical Language (1961) was very influential. In the book, he criticised scholars' reliance on
linguistically flawed arguments, such as arguments from
etymology or based upon misconceptions about the relation between
Hebrew thought and language. Much of Barr's critique was built upon the work of French linguist
Ferdinand de Saussure. In turn, Barr's student
Moisés Silva built on Barr's work in
Biblical Words and Their Meaning (1983). In another important study,
Comparative Philology and the Text of the Old Testament (1968), the Scottish scholar criticised the tendency to ascribe meanings to difficult Hebrew words based on words in other Semitic languages (e.g., Ugaritic). This study has been described as having "put comparative Semitic philology on a new and firmer footing." He edited
Journal of Semitic Studies 1965–1976, and served as editor of the
Oxford Hebrew Dictionary project. He was also an outspoken critic of
conservative evangelicalism, which he attacked in his 1977 book
Fundamentalism. In particular he criticised evangelical scholars such as
J. I. Packer for affirming the doctrine of
scriptural inerrancy, the teaching that the Bible is without error. Barr's other works about fundamentalism include
The Scope and Authority of the Bible (1980) and
Escaping Fundamentalism (1984). He was often invited to appear in BBC religious programming. == Personal life ==
