FTP, name this man who, along with Ernst Weber, was a founder of psychophysics.
One of this man's contributions was proposing an "aesthetics from below," an empirical theory by which simple objects were ranked by how many subjects found them visually pleasing. He satirized the apparent medical belief that iodine was a panacea in "Proof That Man is Made of Iodine," written under his pseudonym Dr. Mises. He posited three periods of human existence beginning with sleep until birth, then "sleeping and waking," then permanent wakefulness after death in his The Little Book Concerning Life after Death. He also composed a work on the "Nanna" or "soul of plants," a worldview he continued to expound in his treatise Zend Avesta: On the Things of Heaven and the Hereafter. More famously, he showed that the log of the physical magnitude of stimulus multiplied by a constant is equal to perceived magnitude of a sensation.
