Os Guiness said that true freedom is only possible within moral boundaries. He wrote in A Free People’s Suicide: “[freedom] rests on strong convictions about what is true and equally strong constraints against what is false. A culture with no claims on its members or – curbs on their desires–would be a culture with no future. Freedom requires a firm refusal of what is false, what is bad, what is excessive, what is ugly and above all, what a person is not and should never try to become. When everything is tolerable, nothing will be true; and when nothing is true, no one will be free.” So in other words, if there is such a category as freedom, there must be conditions that make freedom possible.
