22.28

來論又云。歘而生者歘而滅者。漸而生者漸而滅者。請借子之衝以攻子之城。漸而滅謂死者之形骸始乎無知而至于朽爛也。若然則形之與神本為一物。形既病矣神亦告病。形既謝矣神亦云謝。漸之為用應與形俱。形始亡未朽為漸神獨不得以始末為漸耶。

Your treatise also says: "Those that arise suddenly perish suddenly; those that arise gradually perish gradually." Allow me to borrow your own battering ram to attack your city wall. By "perishing gradually," you mean that the physical remains of the deceased begin as insentient and culminate in rotting away. If that is so, then body and spirit are fundamentally a single thing: when the body falls ill, the spirit likewise reports illness; when the body perishes, the spirit likewise perishes. The working of gradualness should proceed together with the body. When the body has just died and not yet decayed, this constitutes gradualness; why alone should the spirit not undergo gradualness from beginning to end?
