t theory explains that the soul cannot be destroyed by death. It compares thesoul and the body to a string instrument, i.e. a lyre, and when the lyre is destroyed, so is the harmony, as with the body. The harmony of an instrument is a composite thing, which the soul is not. Composites cannot preexist their components. When the lyre is destroyed, so is the harmony; however, the soul cannot be destroyed for it is not a composite thing such as harmony, which means the soul is able to preexist its component (the body). Another argument is that the body may only be a garment for the soul. The garment will wear out eventually and the tailor that made this garment will also expire at some point. Suggesting that the body is a garment and the soul is a tailor, it may be the case that although the soul may exist after death, it may not exist infinitely, and eventually expire. Since the soul can oppose the body, the soul chooses to admit death. If the soul admits death, then the soul may perish. If the soul does not admit death, the soul is deathless, and if the soul is deathless then the soul is indestructible.Our souls know the concept of the forms, and are the same throughout all souls. Since we cannot change the concept of these forms without creating confusion, all souls must have gotten this shared knowledge when the soul was separate from the body, i.e. death and before life. From this we understand that forms exist and as we learn we recollect these forms throughout our bodily life....
