Slippery Slopism

The first is an article by Steven Nadler, a philosopher at Wisconsin, who argues in a contribution at Time that the one weird trick to solve America’s stupidity crisis is a basic course in critical thinking.

What is the solution to our creeping national stupidity? Learning how to gain more information from a variety of certifiably reliable sources is an important first step. But what the American public really needs are lessons in how to be rational, how to assess that information — distinguishing between real evidence and fake evidence — and end up believing only what one is justified in believing. We could use more lessons on what it means to be rational and how to be epistemologically responsible citizens who are familiar with the difference between a valid and invalid argument, and who know an unjustified belief when they see one.

No argument here.

The second link is a medium-long piece by Jay Nordlinger of National Review on the subject of Confederate monuments. Along the way to making the (to me, obvious) point that the Confederacy represented an unequivocal moral evil, Nordlinger went meta and made the following remark about slippery slope arguments:

William F. Buckley Jr. used to warn against “slippery-slopism,” as he called it. There were always people saying, If you ban Hustler magazine from the public library today, you will ban D. H. Lawrence tomorrow. Bill hated this kind of thinking. It was a kind of anti-thinking. People should make judgments, he said. People should exercise their powers of discrimination.

I, however, have always been soft on slippery-slope arguments. And I make them. But I also think Buckley had a point: People should not be excused from thinking.

If you dishonor John C. Calhoun, do you have to dishonor Thomas Jefferson?  If you take Calhoun’s name off a college within Yale University, do you have to raze the Jefferson Memorial? Do you have to change the name of our nation’s capital, because Washington owned slaves? Oh, come on.

This is a clumsily stated but not unreasonable point. The only thing surprising to me–and I’m willing to consider this a consequence of professional deformation–is the novelty with which the subject matter is presented: “hey, have you ever thought about slippery slopes?” Of course you have. (Or maybe you haven’t, if so, you should; that’s Nadler’s point).

The slippery slope is a bread-and-butter topic of any worthy critical reasoning course. Justly so. Sadly, as Buckley correctly suggests, people frequently abuse the term as well as the argument form (for abuse of terms see this post by Scott). They do so especially when the matter regards permitting or prohibiting something. If we prohibit x, then logic dictates we prohibit y, and then it will further require that we prohibit z. The chain itself of increasingly horrible consequences does the work of the argument. In the present case, should we remove the statues of Confederate soldiers, etc., then logic requires we remove the statues of other morally problematic figures (like George Washington)  then there will be no statues (or something).

Buckley’s point is that this energy-saving line of thought absolves you of addressing the question as to whether reasons apply the same way in the separate cases. The slope is actually slippery, though I wonder whether we should use this term (maybe another time for that claim), when the reasoning applies in the separate cases. In these cases, however, what you actually have is a parity of reasons argument. The same reasons that allow x also allow y. A somewhat recent example. When the Bush administration invited religions to collect federal money for charitable activity, Wiccans showed up (to the dismay of the Bush administration). A quick note on the slope here: I hardly think the Wiccans would consider themselves the bottom of any kind of slope.

Sadly, Nordlinger seems to obscure this distinction and fall exactly into the cognitive efficiency  problem Buckley identifies, only in his case rejects the possibility of a parity of reasons case out of hand. This is a point any (again worthy) critical thinking course ought to make–not all slippery slopes are fallacious. Fallacious slippery slopes is that you don’t do any real analytical work. The problem in rejecting parity of reasons arguments out of hand is to do the same thing.

Never argue with a Sicilian when homosexual sodomy is on the line

That’s Sicilian

It’s slippery slope week.

Here’s a snippet from Justice Antonin Scalia’s dissent on yesterday’s SCOTUS ruling on gay marriage:

When the Court declared a constitutional right to homosexual sodomy, we were assured that the case had nothing, nothing at all to do with “whether the government must give formal recognition to any relationship that homosexual persons seek to enter.” Id., at  578. Now we are told that DOMA is invalid because it “demeans the couple, whose moral and sexual choices the Constitution protects,” ante, at 23—with an accompanying citation of Lawrence. It takes real cheek for today’s majority to assure us, as it is going out the door, that a constitutional requirement to give formal recognition to same-sex marriage is not at issue here—when what has preceded that assurance is a lecture on how superior the majority’s moral judgment in favor of same-sex marriage is to the Congress’s hateful moral judgment against it. I promise you this: The only thing that will “confine” the Court’s holding is its sense of what it can get away with. 

Justice Scalia may indeed be correct about the alleged inconsistency; The court may have previously held that Lawrence v Texas wouldn’t entail gay marriage, but then in Windsor they use the legality of “homosexual sodomy” to justify not discriminating against gay marriages.  This, he maintains, shows the slippery slope from “homosexual sodomy” to gay marriage.

A few points.  First, since I’m not a legal scholar, I don’t know if the court has to maintain its promises–or whether the court can make promises like this.  The gay marriage case wasn’t before the court at the time, and, as far as I know, the court decides only the cases it has before it.  It would seem completely wrong for them to adjudicate such things in advance.

Second, inconsistencies are not ipso facto signs of dishonesty.  I like to think my current correct views are inconsistent with my past incorrect ones.  I also sincerely hope that my future correct views are inconsistent with my current incorrect ones.

Third, not all slippery slopes are fallacious.  The court has recognized a right to “homosexual sodomy.”  This means that homosexual relationships are not inherently inferior to heterosexual ones.  This does in fact seem to entail that homosexual commitments differ in the same regard: i.e., not at all.
