A Pluralistic Universe

He published physical treatises and experimental investigations of his own, especially in electricity. Electrical measurements, as you know, are the basis of electrical science, and Fechner’s measurements in galvanism, performed with the simplest self-made apparatus, are classic to this day. During this time he also published a number of half-philosophical, half-humorous writings, which have gone through several editions, under the name of Dr. Mises, besides poems, literary and artistic essays, and other occasional articles. But overwork, poverty, and an eye-trouble produced by his observations on after-images in the retina (also a classic piece of investigation) produced in Fechner, then about thirty-eight years old, a terrific attack of nervous prostration with painful hyperaesthesia of all the functions, from which he suffered three years, cut off entirely from active life.
