In this article, first of all, the thesis of Rajah has been proved by revealed proofs and then, in dealing with metempsychosis, its most important proofs of absurdity are being investigated by critical analyses. Concentrating on the premises and requirements of these proofs, they are criticized by new and initiative objections and it is resulted that: 1-None of them invalidates the conviction of Rajah. 2-Regarding five proofs of absurdity of all kinds of metempsychosis, the first proof is valid, but only on the foundation of either the thesis of substantial movement or the thesis of union of the intelligent with the intelligible,the second proof invalidates only absolute metempsychosis, the fifth proof, on the foundation of the thesis of union of the intelligent with the intelligible invalidates only some kinds of metempsychosis, the two other proofs are invalid. The proofs of absurdity of absolute metempsychosis are valid and the first proof of the two proofs of absurdity of descendant metempsychosis invalidates only some views of supporters of this kind of metempsychosis. The second proof of absurdity of descendant metempsychosis and the proof of absurdity of ascendant metempsychosis are both invalid.
