Black holes, and other causal horizons e.g. de Sitter horizons in cosmology, obey laws of thermodynamics reminiscent of ordinary thermal systems. I will explain the definition and proof of the Generalized Second Law for causal horizons, and discuss its relationship to lower bounds on the stress-energy
tensor in classical and quantum field theories.
