A skill I’ve been refining over time is leading atheists who are trying to argue with me into admitting that they reject reason. Typically by getting them to say that the laws of logic aren’t true, that reason cannot reach truth, or that logic does not describe reality. If I were fourteen, I would probably do that because it’s a game and fun to outwit them. Since I will soon be bidding goodbye to my 30s, I have a practical reason for it.
Christians have a duty to give the truth to anyone who will accept it. However, modern technology (such as twitter, comments to YouTube videos, etc) has put each of us into contact with more people than one can possibly talk to in a lifetime. Worse, there is a minority of people who love to waste other people’s time who go around looking for people whose time they can waste. Since they will merrily go from victim to victim, one such person can waste the time of hundreds; this greatly magnifies the problem for those open to talking with strangers.
As a result, it is only practical to become efficient at weeding out people who are not talking in good faith. The difficulty is that since their purpose is not honest they will try to disguise themselves as honest questioners. However, they cannot hold an actual position or there quickly becomes nothing to say. If they pretended to some particular belief they would quickly end up where actual believers of that belief did, which is at the stalemate of differing perceptions of the universe. Hindus and Christians, for example, rarely argue because they simply have incompatible starting points, and there’s not to say about that.
When it comes to trying to waste the time of Christians, a popular approach these days is “lack of belief” atheism. I’ve written and done videos about this extensively, but the short short version is that they don’t lack a belief, they only pretend to, so that they can pretend that they don’t actually have a position. But of course since they live in the world whether or not God created the world and gives it purpose is of fundamental importance and unavoidable. By living, one either acts in ways compatible with God’s purpose for the world or one acts in ways incompatible with it. If the atheist is not living exactly as if God exists—and they never do—then he is behaving inconsistently with his profession that he has no idea whether or not God exists.
When this is pointed out to them they will try to squirm out of it in various ways, but in my experience the most popular, by far, is some variation of rejecting reason. “I’m not being inconsistent if contradictions can be true!” they say, only far less clearly. They don’t want to be clear, of course, because the moment one rejects reason the game is up. There’s no point in talking to a man who rejects reason.
This is both because language is fundamentally rational, and because nothing can possibly be achieved by trying to reason a man into a conclusion when he rejects reason. No matter how good your argument, he will simply reject some step in it because he can reject any step in it as his whim.
So, to sum up, when a stranger is asking questions on the internet and especially if they’re things he should already know with a few minutes of reading if he was actually interested, it can save a lot of time to force him into admitting some unpleasant consequence of his claimed position—or lack thereof. If he actually believes it, he’ll admit what comes along with it. If he’s just trying to waste your time, he’ll try to wriggle out of it and odds are very good he’ll deny reason.
It’s not an insincere denial, and those who deny reason tend not to have much foresight.
