Grotius on Property and the Right of Necessity

It is widely held that in situations of peril, it is permissible to use another’s property without her permission if that is the only way to save oneself from serious harm, but that if one damages or consumes that property, one ought to compensate its owner. However, this idea—that there is what is commonly called ‘the right of necessity’—has proven surprisingly difficult to justify. According to Grotius, the right of necessity issues from a constraint imposed by natural law on the positive law of private property. I defend an interpretation of Grotius’s account of property and the right of necessity against some recent sympathetic readers, and show how he escapes a seemingly telling criticism from Pufendorf.
