 While the definition of neutral monism may distinguish it clearly from panpsychism, consideration of the extant versions of neutral monism has tended to suggest a different picture. The allegedly neutral basic entities of traditional neutral monism strike many as manifestly mental (see section  7.2  above). This is not the place to assess the accuracy of this impression. But there can be little doubt that it is the source of the wide-spread suspicion that neutral monism is best understood as a version of panpsychism or of phenomenalism.
