 Quine’s terminology in this area differs from that of Strawson, Wiggins and Geach. In 1960 he uses the expression “term that divides its reference”, but in other writings (1969, 1981) he uses the expression “individuative word”. In footnote 1 of Quine 1960: 90 he says that his expression is equivalent to Strawson’s “sortal”. Unfortunately, that cannot be exactly true since 1960: 91 Quine says that “object” divides its reference, though we have seen “object” is not a sortal by the criteria of Strawson or Wiggins because it does not enable counting.
