which it would be dissolved would be the last part of it.

But if the universe was generated, it was generated together with all things; and if it should be corrupted, it would be corrupted together with all things. This, however, is impossibleThe universe could not be generated together with all things, for the principle of it must be unbegotten; since everything that is generated is generated from a cause. If this cause were also generated, there would be a progression of causes ad infinitum (to infinity), unless the unbegotten is admitted to be the principle of the universe. Neither, therefore, can the universe be corrupted together with all things; for the principle of it, being unbegotten, is also incorruptible; that only being corruptible which was once generated.. The universe, therefore, is without a beginning and without an end; nor is it possible that it can have any other mode of subsistence.

To which may be added that everything which has received a beginning of generation, and which must also participate in dissolution, undergoes two mutations. One of these proceeds from the less to the greater, and from the worse to the better; that from which it begins to change is denominated generation, but that at which it at length arrives is called acmeThe peak or highest point of development.. The other mutation, however, proceeds from the greater to the less, and from the better to the worse; the termination of this mutation is denominated corruption and dissolution.
