Thomas Aquinas famously held that (A) theft is always wrong, and also that (B) it is permissible for a starving man to take the bread he needs, openly or secretly, from another. He reconciled these two positions by claiming that (C) in cases of great need, it is not theft to take someone else’s property when she does not need it herself. On its face, (C) looks like a theoretically costly concession that Aquinas is forced into in order to reconcile (A) and (B). Our first aim is to show that this is not so. We argue that (C) is in fact the only way to accommodate a set of intuitive norms of keeping and taking. Our second aim is to show that (C) has important implications for theories of property more generally: a plausible theory of property must acknowledge a foundational sense of "belong" on which things belong to those who need them.

What a person is doing often depends on that person’s thought about what they are doing, or about the wider circumstances of their action. For example, whether my killing is murder or manslaughter depends, in part, on whether I understand that what I am doing is killing you, and on whether I understand that my killing is unjustified. Similarly, if I know that the backpack I am taking is yours, then my taking it may be an act of theft; but it is not theft if I simply mistook your backpack for my own. And if I don’t know that in signing a document I’m promising to do some thing, then in signing it I’m not promising to do this at all. According to Elizabeth Anscombe, a central task of philosophical psychology is to articulate this dependency of action on thought. And in a range of papers published during the 1960s, Anscombe sought to elucidate various aspects of this dependency. In this paper we give a systematic overview of how Anscombe understands this dependency, and in the process reveal the conceptual framework underlying Anscombe’s thinking about perception, desire, intention, voluntariness, responsibility, guilt, and sin.
