Housing the powers? What powers? Soul powers — powers that shape the lives of human souls. They may be housed, and exercised, by those souls or by other agents. This book is about views on that subject developed by Christian philosophical theologians in western Europe from the mid-12th to the early 14th century, with some borrowing of thoughts from their Islamic counterparts. Chapters 1 to 3 discuss in increasing breadth and depth those theologians' views about their own housing and exercise of soul powers. Chapters 4 to 8 discuss their views as to the possibility of some of our soul powers being outsourced — that is, housed and exercised by God or a super-human emanation of God. Chapter 4 is about outsourcing the subject — in an Islamic form that postulated an outsourcing of intellectual thinking from individual human beings to a single intellect that is eternally emanated from God and is the sole thinker of all the thoughts that humans ever think. That theory attracted the interest, though not the agreement, of European Christian philosophers. They found ideas of outsourcing the object, rather than the subject, of religious thought more congenial. The remaining four chapters of the book deal with that more congenial topic. In chapters 5 and 6 the focus is mainly on divine gifts of knowledge and understanding, and in chapters 7 and 8 on gifts of action and willing or desire.
