Extract

In his paper, “Grand Unified Gauge Theories and the Number of Elementary Particles,“ Robert Weingard (1984) suggests what he calls the Extended Redhead's Principle (ERP) for elementary particles: “Two particles for which there are conceivable circumstances in which one can be ‘rotated’ or reoriented into the other are the same (species of) particles” (p. 154). The philosophical soundness of such a principle is questionable.
