This is a talk that I gave at the BRAK (Brno Analytic Conference CaL2019: Cognition and Lying) conference at Masaryk University in Brno, in the Czech Republic, on November 28, 2019. I give reasons for holding that lying is worse than deceiving people with untruthful statements (which may or not may be lying), because it involves betraying trust as well as deception, and worse than misleading people with truthful assertions, because it involves being untruthful.
