Thomas Aquinas on the Immateriality of the Human Intellect

The chief aims of Thomas Aquinas on the Immateriality of the Human Intellect are to provide a comprehensive interpretation of Aquinas's oft-repeated claim that the human intellect is immaterial, and to assess his arguments on behalf of this claim. Adam Wood argues that Aquinas's claim refers primarily to the mode in which the human intellect has its act of being. That the human intellect has an immaterial mode of being, however, crucially underwrites Aquinas's additional views that the human soul is subsistent and incorruptible. To show how it does so, Wood argues that the human intellect's immateriality can also be put in terms of the impossibility of explaining its operations in terms of coordination between bodily parts, states and processes. Aquinas's arguments for the human intellect's immateriality, therefore, can be understood as attempts to show why intellectual operations cannot be explained in bodily terms. The book argues that not all of them succeed in this aim and also proposes, however, a novel interpretation of Aquinas's argument based on human intellect's universal mode of cognition that may indeed be sound. Wood concludes by considering the ramifications of Aquinas's position on matters pertaining to the afterlife.
