Wherefore, whoever he be who deems himself happy because of license to revile, he would be far happier if that were not allowed him at all; for he might all the while, laying aside empty boast, be contradicting those to whose views he is opposed by way of free consultation with them, and be listening, as it becomes him, honorably, gravely, candidly, to all that can be adduced by those whom he consults by friendly disputation.
- St. Augustine
