QBism puts the scientist back into science

摘要

Physical science describes the objective external world: particles, waves and fields; how they change in time; and how they give rise to the forms of matter, terrestrial and extraterrestrial, microscopic and macroscopic. This world makes itself known to each of us through our own private internal perceptions. Yet physical science has ignored the 'subject' - the scientist - even though their subjective experience constitutes their only link with the external world. In Nature and the Greeks, Austrian physicist Erwin Schrodinger traced the removal of the subject from science back more than two millennia. Alongside the spectacular success of physical science, this exclusion of personal experience has given rise to some vexing and persistent puzzles and paradoxes.
