Next, we subvert it, if what is said to exist is not the property of what is said to exist, since neither will to be corrupted be the property of that which is said to be corrupted, nor to be generated of what is said to be generated. For instance, since it is not the property of man to be animal, neither will to be generated animal, be the property of to be generated man, nor will the corruption of animal, be the property of the corruption of man. After the same manner, we must assume (the argument) from being generated to existence and being corrupted, and from being corrupted to existence and being generated, as was just now said from existence, to the being generated and corrupted. Again, we confirm it, if of what is arranged according to existence, the property is that which is arranged according to the same, for what is said to be according to the being generated, will also be the property of what is said to be according to the being generated, and of what is said to be corrupted that which is assigned according to this. Thus, since to be mortal is the property of man, to be generated mortal would also be the property of the being generated man, and the corruption of mortal of the corruption of man. In the same way, indeed, we must take the argument, both from the being generated and the being corrupted with regard both to existence and to the same from the same, as was observed to him who subverts.
Next, we must pay attention to the idea of the thing proposed, subverting, indeed, if it be not present with the idea, or if not as to this, according to which that is stated, of which the property is a sign, for what is stated to be, will not be the property. Thus, since rest is not present with man himself, so far as he is man, but so far as he is idea, rest would not be the property of man. We confirm it, indeed, if it is present with the idea, and is present so far as it is predicated of this very thing, of which it is stated not to be the pro-
