ἀγνοουμένων δὲ τούτων οἴχεται καὶ ἡ πρὸς ἀκρίβειαν τῆς συλλήψεως κατά- ληψις. εἴπερ τε, ὥς τινες τῶν φυσικῶν εἰρήκασιν, ἑψό- μενον πρῶτον καὶ προμεταβαλλόμενον ἐν μήτρᾳ τὸ σπέρμα τότε προσέρχεται τοῖς ἀναστομωθεῖσιν αὐτῆς ἀγγείοις, αὐτόθεν οὐκ εἰδότες τὴν ποσότητα τοῦ τῆς μεταβολῆς χρόνου οὐκ εἴσονται οὐδὲ τὸν τῆς συλλήψεως καιρόν.

Since these matters are unknown, the precise apprehension of conception also vanishes. And if, as some natural philosophers have said, the seed is first concocted and undergoes preliminary change in the womb, and only then approaches its opened vessels, then, since they do not know the quantity of time required for this change, they will for that very reason not know the moment of conception either.

Ces choses étant inconnues, la saisie exacte de la conception disparaît elle aussi. Et si, comme l’ont dit certains physiciens, la semence est d’abord cuite et transformée dans la matrice, puis s’approche de ses vaisseaux dont les ouvertures se sont dilatées, alors, puisqu’ils ignorent d’emblée la durée de cette transformation, ils ne connaîtront pas non plus le moment de la conception.
