Okay, I’m trying this again because my ‘logic’ thread became too hard for me to follow…
I argue with people, and they join me in arguing. Other people do this all the time in many other contexts - science, politics, religion, and so on. They all seem to be working on more or less the same rules of how to argue. Now, some are very sloppy and argue in self-contradictory ways, and the most conscientious of us will also make logical errors and get tripped up by fallacies from time to time. This is okay, because these things can be pointed out and the arguing can continue.
But now and then, someone will try to get a leg up by dismissing reason altogether with a statement such as ‘oh that’s just your logic’. (To address a point someone made in the previous thread, I’m talking specifically about the case where someone tries to dismiss formal logic, not just an idiosyncratic set of beliefs they may assume I hold.)
Now, my question is how to repond to this in a way that doesn’t require us both to have studied philosophy. It seems like a foul, but I can’t quite say why. My intuition says that such a person has, simply by engaging in an argument, tacitly accepted the same rules of reason as me, but has abruptly decided to bail out (perhaps because they’re losing the argument). What is the source of this implicit agreement that there is something called ‘argument’ that we are all willing, without question, to engage in? Where does it come from, and on what authority do we do it?
I am not looking for a technical argument here, I’m sure there must be a simple answer to this. The notion of rational thought seems to be a basic pillar of eveything we do. Even those who do not argue rationally at least believe they do, and try to defend their own wooly brand of reason. The point is that they play the game, however imperfectly, and so we can engage with them. But what is the game, where does it come from, and why do people engage in it without question?
