"Radical criticism does not start from the belief that the non plus ultra of critical emancipation has been realized by the Tübingen school; but neither does it think that that school went too far. For it, there is nothing a priori 'too far' in this field; and it believes that criticism is ever duty bound to criticize its own work and repair its own defects. It recognizes no theoretical limit whatsoever that can reasonably be fixed... It wishes nothing better than, mutatis mutandis, to continue the research pursued by the Tübingen school, and, standing on the shoulders of Baur and others, and thus presumably with the prospect of seeing clearer and farther, to advance another stage, as long a stage as possible, towards a real knowledge of Christian history."
