Does it then follow that many human beings are destined to go hungry over the years to come? Yes, even so. But the liberal ideology—which, by clinging to an optimistic theory of human nature and history, by denying the objective reality of evil and affirming that all social problems can be solved, excludes genuine tragedy—cannot face this tragic fact. That is the real reason why the liberal repeats the proposition, derived not from fact but from doctrine, that we have the ability to provide all men with enough food. When the fact is tragic, his ideology offers him refuge from fact.
