 How far the textual evidence on the matter will prove decisive is unclear, especially given the fragmentary nature of Peirce’s final work on signs. However, one or two things militate in favor of the “received view”. First, Peirce is notorious for experimenting with terminology, especially when trying to pin down his own ideas, or describe the same phenomenon from different angles. Second, it is unclear why trichotomies like the intentional/effectual/communicational should count as terminological experiments whilst the emotional/energetic/logical counts as a distinct division. And finally, there is little provision in Peirce’s projected sixty-six classes of signs for the kind of additional classifications imposed by further subdivisions of the interpretant.
