According to quantum theory, the outcomes of measurements are  generally not deterministic. "Single-world" theories (such as Bohmian  mechanics) add additional elements to quantum theory in order to restore determinism. In this talk, I will argue that such single-world theories  cannot be self-consistent in the following sense: any attempt to use a single-world theory to describe an observer who himself applies the  theory necessarily results in a contradiction.
