Abstract

The growing interest in the concept of probability of self-location of a conscious agent created multiple controversies. Considering David Albert's setup in which he described his worries about consistency of the concept, I identify the sources of these controversies and argue that defining ``self'' in an operational way provides a satisfactory meaning for the probability of self-location of an agent in a quantum world. It keeps the nontrivial feature of having subjective ignorance of self-location without ignorance about the state of the universe. It also allows defining the Born rule in the many-worlds interpretation of quantum mechanics and proving it from some natural assumptions.
