 Many philosophers find Moore’s proof unsuccessful. Philosophers have put forward explanations of this impression according to which Moore is non-transmissive in some of the senses described in Sect. 3 (see mainly Wright 1985, 2002, 2007 and 2011) or non-transmissive in the non-standard sense that it is incapable of resolving doubt about its conclusion (see mainly Davies 1998, 2000, 2003a, 2003b, 2004 and 2009). A different explanation is that Moore’s proof does transmit justification but is dialectically ineffective (see mainly Pryor 2004).
