Therefore that which comes to be, when it has come to be coming to be, is then in course of perishingsc. which is absurd.; for it does not perish as soon as it is coming to be coming to be, nor afterwards, because that which is perishing must exist .That which comes to be must cease to be, and it can cease to be only when it exists. Therefore if that which comes to be comes to be coming to be, it must cease to be when it is coming to be; before this it does not exist, but is only coming to be coming to be, and after this it is not that which comes to be but that which has come to be.

Further, there must be some matter underlying that which is coming to be or changing. What then will it be? What is it that becomes motion or generation in the same way as it is body or soul that undergoes change? And moreover what is that which is the terminus of the motion? For that which we are considering must be a motion or generation of A from B into C.

How then can these conditions be fulfilled? There can be no learning of learning, and therefore there can be no generation of generation.
