 The method followed in the reconstruction of Speusippus’ views is a matter of chaining: we start from our two anchor texts, and look for other passages in which the views ascribed to him in them are under discussion. Those passages will sometimes bring in new views; we then ascribe those views to Speusippus, and go looking for passages in which those views seem to be alluded to. No one needs to be told how tenuous such chaining is: each link is weak, and compounding probabilities would tell us that a chain of this type is actually weaker than its weakest link. But chaining in that way is all we can do. Fortunately, it results in a fairly coherent picture.
