immorality of the soul in the view of maimonids

maimonids distinguishes between the resurrection and the next world. he relate the resurrection of the dead to the messianic era and the immorality of the soul to the next world. maimonids tied immorality of the soul with intellectual development of soul in this world. he believes immorality of the soul belongs only to those who have enjoyed the blessing of intellect. therefore, his interpretation of eschatological beliefs differs from common interpretation in judaism. for maimonids, heaven and hell and in general, reward and punishment have described in the level of most people`s understanding. heaven and hell is here and now. in this paper, we try to find an answer to this important question whether his source of inspiration in this theory has been bible and jewish tradition or he has been influenced by greek philosophy, especially aristotle and muslim peripatetics like abu nasr farabi and ibn rushd.
