Many of ideas Ouspensky presents in "Tertium Organum" mention Hinton's works. Hinton's "scientific romance", the "Unlearner", is cited by John Dewey in "Art as Experience", chapter 3. The story described by John Dewey is actually titled "An Unfinished Communication" and is part of the second series of "Scientific Romances". The Unlearner is a character in this story, which might explain why John Dewey confused the title of the story. Hinton is the main character of Carlos Atanes's play "Un genio olvidado (Un rato en la vida de Charles Howard Hinton)". The play was premiered on Madrid in May 2015 and published in May 2017. Hinton is mentioned several times in Alan Moore's graphic novel "From Hell"; his theories regarding the fourth dimension form the basis of the book's final chapter. His father, James Hinton, appears in chapters 4 and 10. He is mentioned twice in Aleister Crowley's novel "Moonchild". The first mention mistakenly names his father, James Hinton. Plantar reflex  The plantar reflex is a reflex elicited when the sole of the foot is stimulated with a blunt instrument. The reflex can take one of two forms. In healthy adults, the plantar reflex causes a downward response of the hallux (flexion). An upward response (extension) of the hallux is known as the Babinski response or Babinski sign, named after the neurologist Joseph Babinski. The presence of the Babinski sign can identify disease of the spinal cord and brain in adults, and also exists as a primitive reflex in infants. While first described in the medical literature by Babinski in 1896, the reflex has been identified in art at least as early as Botticelli's "Madonna and Child With an Angel", painted in the mid-15th century. The lateral side of the sole of the foot is rubbed with a blunt instrument or device so as not to cause pain, discomfort, or injury to the skin; the instrument is run from the heel along a curve to the toes (metatarsal pads). Many reflex hammers taper at the end of the handle to a point which was used for testing the plantar response in the past, however, due to the tightening of infection control regulation this is no longer recommended. Either a single use device or the thumb nail should be used. There are three responses possible:  As the lesion responsible for the sign expands, so does the area from which the afferent Babinski response may be elicited.
