  William is particularly concerned, however, that his account of the intellect's generation of intelligible forms will require a division of the intellect into active and passive parts—the very distinction between an agent and material or receptive intellect he has devoted so much energy to attacking. The need to make this division of the intellect into two part is because it is impossible for the same thing to be both active and passive in the same respect, and yet in treating the intellect as indivisible it looks as though William is in fact committed to its being both active and passive in the same respect in the formation and reception of intelligible forms.
