I will defend a principle at work in Thomas Aquinas’s argument that the human intellect must be immaterial in order to know material things in SummaTheologica, Ia, q.75, a.2. Thomas relies on the position that whatever knows certain things would be impeded in this knowledge if it contained in itself thesesame things. Thus, if humans can, in principle, know all material things, then the intellect cannot be material. The position that a material intellect would be limited in knowledge of material (...) things is perhaps the most controversial part of the argument. I will articulate a version of this argument and argue that two objections to Thomas’s argument, offered by Norman Kretzmann and Robert Pasnau, fail, due in large part to a misunderstanding of proper objects of cognition.

Clarembald of Arras is recognized primarily as a capable but uncreative alumnus of the school of Chartres, and not without some reason, as George and Fortin note in the opening of their introduction. Clarembald was a student of Thierry of Chartres and Hugh of St. Victor in a rather thoroughgoing sense—his written work often relies heavily on his teachers and focuses exclusively on topics on which Thierry had already written. Nonetheless, George and Fortin suggest that a closer reading of Clarembald’s (...) texts will reveal him to be a more careful and important thinker than is presently appreciated. (shrink)

Primary substance for Aristotle is either the individual or form. These same two possibilities are the leading candidates for the source of unity in a substance.Thus, if we could determine what is responsible for the unity of a substance, we may well have located primary substance also. I consider the following possiblesources of the unity of form and matter in a substance:1) The unifier is a connector external to form and matter. (This connector may be itself a form, matter, or (...) a relation that is neither formal nor material.)2) There is no need for a unifier because form and matter are simply conceptual ways of understanding a single, already-unified, concrete being.3) The unifier is an inherent aspect of form or matter.I proceed by a process of elimination and conclude that substantial form is both what unifies a substance and the better candidate for primary substance.
