We describe our recent calculation of the dominant late time behavior of the expectation value of the metric at two loops in a locally de Sitter background on the manifold T{sup 3} {times} {Re}. If correct, our result proves that quantum gravitational effects slow the rate of inflation by an amount which becomes non-perturbatively large at late times. 11 refs., 9 figs., 11 tabs.
