Dissensus profundus

To have a meaningful or maybe productive disagreement you should be able to identify what it is you disagree about. Once, for example, I had a disagreement with a neighbor over whether some or other species of vine was an invasive (it was and she was right). It was easy in that case to point to the source of our disagreement: some factual claim about Boston Ivy (irrelevant side note: there are no climbing ivy species native to Chicago). Crucially, it was also easy to point to a source for confidence in such claims about plants: a plant manual (or something like that).

Sometimes, however, it’s easy to point to what you disagree about, but not easy to find a solution–this is because you disagree about what a solution would be. This is a deep disagreement (check on this project on the topic). You disagree so fundamentally that you disagree about disagreeing.

On this topic today I learned, courtesy of Dr. Sara J.Uckelman’s Medieval Logic and Semantics blog, a Latin phrase for this situation:

Contra negantem principia non est disputandum

Or: “against someone who denies principles there can’t be a debate.”

Well, in some cases, according to Duns Scotus, there is one thing you can do:

Et ideo negantes talia manifesta indigent poena vel scientia vel sensu, quia secundum Avicennam primo Metaphysicae : Negantes primum principium sunt vapulandi vel exponendi igni, quousque concedant quod non est idem comburi et non comburi, vapulari et non vapulari.

And thus those who deny such manifest things need punishment or knowledge or sense, because, According to Avicenna (I Metaphysics): those denying a first principle ought to be beaten or burnt until they concede that being burned is not the same as not being burned and being beaten is not the same as not being beaten.

There you might have a valid case of ad baculum, though I don’t recommend this as a general principle.

Fouling is part of the game

Quote of the day (Aristotle Sophistical Refutations 11 (171b20-35):

So, then, any merely apparent reasoning about these things is a contentious argument, and any reasoning that merely appears to conform to the subject in hand, even though it be genuine reasoning, is a contentious argument: for it is merely apparent in its conformity to the subject-matter, so that it is deceptive and plays foul. For just as a foul in a race is a definite type of fault, and is a kind of foul fighting, so the art of contentious reasoning is foul fighting in disputation: for in the former case those who are resolved to win at all costs snatch at everything, and so in the latter case do contentious reasoners. Those, then, who do this in order to win the mere victory are generally considered to be contentious and quarrelsome persons, while those who do it to win a reputation with a view to making money are sophistical. For the art of sophistry is, as we said,’ a kind of art of money-making from a merely apparent wisdom, and this is why they aim at a merely apparent demonstration: and quarrelsome persons and sophists both employ the same arguments, but not with the same motives: and the same argument will be sophistical and contentious, but not in the same respect; rather, it will be contentious in so far as its aim is an apparent victory, while in so far as its aim is an apparent wisdom, it will be sophistical: for the art of sophistry is a certain appearance of wisdom without the reality. The contentious argument stands in somewhat the same relation to the dialectical as the drawer of false diagrams to the geometrician; for it beguiles by misreasoning from the same principles as dialectic uses, just as the drawer of a false diagram beguiles the geometrician.

This is often the analogy that I use when discussing fallacies. I get little traction, because the students think fouling is part of the game.

Aristotle, On Trolling

This long-overdue translation (by Rachel Barney, Toronto) of Aristotle’s seminal, On Trolling, is worth a careful read. A sample:

Hence the modes of trolling are many: the concern-troll, the one who ‘sees the other side’, the polite inquirer into the obvious. For the perfected troll has no need of rudeness or abuse, or even of fallacy (this belongs rather to sophistic or eristic, and requires making an argument): he only makes a suggestion or indication [semainein ˆ ].

Read it. It’s only two pages.

A couple of items

In case one is interested in how philosophers have reacted to David Brooks' piece (mentioned here yesterday), then they can go over to the Leiter Reports and comment.

In case one is interested in bad arguments in general–as we are–then one can go badarguments.org to practice identifying them.  Have fun.

Finally, if one has been following George F. Will's scientific escapades (discussed by us here and here and here and here and here and here and here and here and here), one might be interested in the following article published in yesterday's Washington Post.  Here's a critical passage:

The new evidence — including satellite data showing that the average multiyear wintertime sea ice cover in the Arctic in 2005 and 2006 was nine feet thick, a significant decline from the 1980s — contradicts data cited in widely circulated reports by Washington Post columnist George F. Will that sea ice in the Arctic has not significantly declined since 1979.

If only the article were distributed as widely as Will's various factually and logically challenged op-eds.  Here's Tom Toles (of the Washington Post!) on George Will:

 

Phronesis

General philosophical post today.  It doesn't seem David Brooks has read Aristotle.  Had he read Aristotle, he would have not written this:

Socrates talked. The assumption behind his approach to philosophy, and the approaches of millions of people since, is that moral thinking is mostly a matter of reason and deliberation: Think through moral problems. Find a just principle. Apply it.

Discuss. 

UPDATE.  Ok, on the strength of a conversation with one of the commentators here, I will add the following two paragraphs (directly from above) to make the Aristotle point clearer.

One problem with this kind of approach to morality, as Michael Gazzaniga writes in his 2008 book, “Human,” is that “it has been hard to find any correlation between moral reasoning and proactive moral behavior, such as helping other people. In fact, in most studies, none has been found.”

Today, many psychologists, cognitive scientists and even philosophers embrace a different view of morality. In this view, moral thinking is more like aesthetics. As we look around the world, we are constantly evaluating what we see. Seeing and evaluating are not two separate processes. They are linked and basically simultaneous.

Now discuss (again).
