Agnosticism is worse than atheism in that the conviction against atheism is simpler. The saying "an idle mind is the devil's playground" encapsulates agnosticism. Christ says, "What does it profit a man if he gain the whole world but lose his soul?" So it is with the 'playground' of agnosticim. The Biblical epistle containing admonition about "progressives" is an early example of conviction against agnosticism. The early 20th century encyclical against the modernists is a more, recent warning about such frivolousness of thought.
