 The second half of the book, the author tells us, was about the number 10, the decad. Unfortunately, the description of that half of the book that precedes the quotation contains some wording which it seems impossible to ascribe to Speusippus. The author tells us that Speusippus showed that the number 10 was “a sort of artistic form for the cosmic accomplishments, obtaining in its own right (and not because we use it nor as it happens), and lying before the god that is maker of the all as an all-complete paradigm” (De Falco/Klein 1975, p. 83.2–5, Waterfield 1988, p. 112). The trouble is that we have already got Speusippus rejecting the Theory of Forms, and in particular denying that aspect of the Theory in which the forms are treated as ‘paradigms’: ideal cases that transmit their properties to things that participate in them.
