   The first and fourth intellects do not conjoin, though al-Kindî would have the perfect soul ascend to its creator. Similarly, he is not explicit as to the relationship of the imagination and intellect; the imaginative forms, recognized as partially abstracted from matter, should provide the raw material for the intellect, but it is not at all clear they do. The Platonic disparagement of sensibilia may have affected al-Kindî here, leaving his psychology ultimately dualistic.
