On the morning of October 22, German philosopher, physicist, and psychologist Gustav Fechner received an insight into the mathematical nature of the mind-body relation. Both Fechner's law and the semireligious nature of his revelation are described in many histories of psychology. The International Society for Psychophysics continues to hold its annual convention on a date close to October 22.
