There is a schizophrenic nature in modern politics. A leader is expected to have a religious faith but he is not supposed to let it influence him in his duties. Somehow, the truths that determine everything else about his existence are not allowed to influence how he conducts himself in public life. Not only that, his principles are usually considered so personal that the public is not even allowed to know for certain what they are. This passes for noble statecraft in our time. It was once thought cowardice.
