 None of the works just mentioned include the term “epiphenomenalism”. I have located three articles in Mind in the 1890s that do use the term (the earliest, in 1893, hyphenates it as “epi-phenomenalism”). The earliest occurrence of the term for referring to automatism that I have been able to locate is in William James’s The Principles of Psychology, first published in 1890. It occurs in his chapter “The Automaton-Theory” once, in scare quotes; the rest of the time, the view is referred to as the “automaton-theory” or the “conscious automaton-theory”. James attributes the origination of the view to Shadworth Hodgson, in The Theory of Practice (1870). A section of this work titled “Dependence of consciousness on nerve movement” does indeed contain a forthright statement of the view (without “epiphenomenalism”, “automatism” or any other “-ism” tag).
