Certain general conditions are put forth on a complete simply-connected Riemannian manifold of nonpositive curvature which guarantee that they support nontrivial bounded harmonic functions. This result includes the Cartan-Hadamard manifolds with curvature pinched between two negative constants and the bounded symmetric domains and (n a parts per thousand yen 2) as special cases.
