It is quite unlawful to demand, defend, or to grant unconditional freedom of thought, or speech, of writing or worship, as if these were so many rights given by nature to man.
POPE LEO XIII
The liberty of thinking and publishing whatsoever each one likes, without any hindrances, is not in itself an advantage over which society can wisely rejoice. On the contrary, it is the fountainhead and origin of many evils.
