 The complete metaphysical scheme of the Timaeus that is summed up at 50c7–d4 and again at 52a1–b5 is thus as follows: (i) the eternal and unchanging forms, the “model,” or “father”; (ii) the receptacle, or “mother,” and (iii) the copies of the model or “offspring” of the father and the mother. These three are the components of Plato’s analysis; they are not three ontologically distinct ingredients. The receptacle is introduced not as a distinct entity newly superadded to particulars and forms, but as a new and essential component in the analysis of what it is to be a spatio-temporal particular. What is missing from that analysis, however, is any mention of character types or tokens, and while later philosophers might see a use for such concepts in elucidating the metaphysical scheme of the Timaeus, it is not clear that Plato himself makes any use of them there.
