摘要：
A topological field theory of gravity in four-dimension is proposed which is finite after quantization. Since such 'minimal' BF type models for the high energy limit are physically not quite realistic, a tiny symmetry breaking is needed to recover standard Einsteinian gravity for the macroscopic metrical background.
