 Soft paternalism is the view that the only conditions under which state paternalism is justified is when it is necessary to determine whether the person being interfered with is acting voluntarily and knowledgeably. To use Mill’s famous example of the person about to walk across a damaged bridge, if we could not communicate the danger (he speaks only Japanese) a soft paternalist would justify forcibly preventing him from crossing the bridge in order to determine whether he knows about its condition. If he knows, and wants to, say, commit suicide he must be allowed to proceed. A hard paternalist says that, at least sometimes, it may be permissible to prevent him from crossing the bridge even if he knows of its condition. We are entitled to prevent voluntary suicide.
