These are excerpts and elaborations from my book "The Nature of Consciousness"
Richard Feynman (“Space-Time Approach to Non-Relativistic Quantum Mechanics”, 1948) offered yet another interpretation of Quantum Theory: he assumed that all possible states allowed by a wave function exist at any moment. In other words, he took Schroedinger’s equation to the letter. The state that is revealed by measurement is merely the state which represents the “path of least action” for the particle relative to the observer. But the particle is in every place allowed by its wave function. An observation does not reveal reality: an observation is an interaction between the observer and the observed system, and the observation simply reveals that: the interaction between the observer and the observed system. In a sense, the observer “invents” the particle. The particle per se does not exist (or, better, it is merely a field). What exists is a range of values, or, better, a set of ranges of values, which our observations translate into values for attributes of a particle.
