We show that the retarded interaction between quasiparticiles on a 2D square lattice induced by the exchange of antiferromagnetic paramagnons leads uniquely to a transition to a superconducting state with {ital d}{sub {ital x}}{sup 2}{minus}{ital y}{sup 2} symmetry. With a spin-excitation spectrum and a quasiparticle-paramagnon coupling determined by fits to normal-state experiments, we obtain high transition temperatures and energy-gap behaviors comparable to those measured for YBa{sub 2}Cu{sub 3}O{sub 7}, YBa{sub 2}Cu{sub 3}O{sub 6.63}, and La{sub 1.85}Sr{sub 0.15}CuO{sub 4}.
