St. Augustine was not only aware of the endless “conversations about conversations”, but he understood their true purpose and nature. DISCUSS ON SG.
And yet, will we ever come to an end of discussion and talk if we think we must always reply to replies? For replies come from those who either cannot understand what is said to them, or are so stubborn and contentious that they refuse to give in even if they do understand. In fact, as the Bible says, ‘Their conversation is unrighteousness and they are indefatigable in folly.’
You can see how infinitely laborious and fruitless it would be to try to refute every objection they offer, when they have resolved never to think before they speak provided that somehow or other they contradict our arguments.
The City of God, Augustine
