This work re-evaluates the life and thought of George Tyrrell, one of the most prominent of the modernist thinkers, on the centenary of his death. A Jesuit priest, he was dismissed from the order and excommunicated from the church for his views. The problems he tried to grapple with – the relation of science to religion, questions of meaning and modernity, issues of the articulation of Christian ideas in modern culture – have a peculiarly contemporary ring. These articles attempt to set Tyrrell’s work within the framework of early 20th-century Catholic ideas and to draw some conclusions about his thinking for present day concerns.
