In replying to my criticism of his interpretation of this passage, Professor H-N. Castañeda has disregarded much of my argument. In particular, he has ignored my contention that a contrast between 'essential’ and ‘accidental’ predication is integral to the wider argument for immortality in which Phaedo 102b-d is embedded. This would remain the case whatever the grammar of 102b-c, and whatever the exact force of πεφυxέναι and τυγχάνει at 102c1-2. Further, Castañeda pays no heed to the difficulty of interpreting Plato's other relational examples in his way, given that no analysis parallel to that of 102b-d is anywhere hinted at for them. Moreover, he disregards the difficulty that several other examples in the nearby context are analysed in terms of the Theory of Forms, and yet are not overtly ‘relational’ in the usual sense at all.

Castañeda says (note 12) that it is ‘clear’ from my own translation of several passages (72e6, 103e7, 109d4, 110b2, 111c2, etc.) that τυΥχάνει in the Phaedo ‘has nothing to do with accident.’
