Abstract :
In the paper “Incompatibility between quantum theory and consciousness” by Daegene Song is presented mathematical argument according to which quantum theory and self-observing consciousness are incompatible. Here we spot a critical mathematical error in Song’s equations, showing that Song’s argument is mathematically messed and is quite irrelevant for solving issues concerning consciousness. Moreover, Song’s error does not apply specifically for quantum mechanics but for any unitary transformation in configuration space.
