Abstract
We investigate the relaxation of general scalar-tensor gravity theorie s towards general relativity. We extend Damour and Nordtvedt's work [P hys. Rev. Lett. 70 (1993) 2217; Phys. Rev. D 48 (1993) 3436] by includ ing a cosmological potential. We find that Einstein's gravity is indee d a cosmological attractor both for isotropic and anisotropic universe s, and that the universe exhibits inflationary expansion during the re laxation process.
