Historian Alexandra Walsham notes that the modern understanding of the word "toleration" may be very different from its historic meaning. Toleration in modern parlance has been analyzed as a component of a liberal or libertarian view of human rights. Hans Oberdiek writes, "As long as no one is harmed or no one's fundamental rights are violated, the state should keep hands off, tolerating what those controlling the state find disgusting, deplorable or even debased. This for a long time has been the most prevalent defense of toleration by liberals... It is found, for example, in the writings of American philosophers John Rawls, Robert Nozick, Ronald Dworkin, Brian Barry, and a Canadian, Will Kymlicka, among others."
