If there was one intellectual development in living memory that separates the “grandparent” from the “parent” generation of British theology, it was the rise of logical positivism and analytical philosophy. A fairly homogeneous educated class, largely shaped through a few major universities, received a massive assault from within those universities not just on its philosophy but on its beliefs, ethics and worldview. “But how can you prove . . .?” “But what do you really mean by . . .” were the reigning questions, and the conclusion of the inquiry was usually that your meaning had no empirical basis and did not make sense. The assault was made by a confident army of elite intellectuals, who appropriated the prestige of modern science and offered a rational rigor that might provide a place (however confined) to stand amidst world wars and huge changes in every area of life.
