The US and North Korea: Posturing v pragmatism

by Emrys Westacott

On September 19, Donald Trump spoke before the UN general assembly. Addressing the issue of North Korea's nuclear weapons program, he said that the US "if it is forced to defend itself or its allies, . . . will have no choice but to totally destroy North Korea." And of the North Korean leader Kim Jong-un, he said, "Rocket Man is on a suicide mission for himself and his regime." Download

There is nothing new about the US president affirming a commitment to defend itself and its allies. What is noteworthy about Trump's remarks is his cavalier talk of totally destroying another country, which implicitly suggests the use of nuclear weapons, and his deliberately insulting–as opposed to just criticizing–Kim Jong-un. He seems to enjoy getting down in the gutter with the North Korean leader, who responded in kind by calling Trump a "frightened dog," and a "mentally deranged dotard." Critics have noted that Trump's language is closer to what one expects of a strutting schoolyard bully than a national leader addressing an august assembly. And one could ask interesting questions about the psychological make-up of both men that leads them to speak the way they do. From a moral and political point of view, though, the only really important question regarding Trump's behavior is whether or not it is sensible. Is it a good idea to threaten and insult Kim Jong-un.

As a general rule, the best way to evaluate any action, including a speech act, is pragmatically: that is, by its likely effects. This is not always easy. Our predictions about the effects of an action are rarely certain, and they are often wrong. Moreover, even if we agree that one should think pragmatically, most of us find it hard to stick to this resolve. How many parents have nagged their teenage kids even though they know that such nagging will probably be counterproductive? How many of us have gone ahead and made an unnecessary critical comment to a partner that we know is likely to spark an unpleasant and unproductive row? And if one happens to be an ignorant, impulsive, narcissist, the self-restraint required in acting pragmatically is probably out of reach. Which is worrying when one considers how high the stakes are in the verbal cock fight between Trump and Jong-un.

Fallibilism and its Discontents

by Scott F. Aikin and Robert B. Talisse

JTxEnx5BcFallibilism is a philosophical halo term, a preferred rhetorical mantle that one attaches to the views one favors. Accordingly, fallibilists identify their view with the things that cognitively modest people tend to say about themselves: I believe this, but I may be wrong; We know things but only on the basis of incomplete evidence; In the real world, inconclusive reasons are good enough; I'm open to opposing views and ready to change my mind. But there are different kinds of epistemic modesty, and so different kinds of fallibilism. Let's distinguish two main kinds of fallibilism, each with two degrees of strength:


Weak: It is possible that at least one of my beliefs is false.

Strong: Any one of my beliefs may be false.


Weak: It is possible that I know something on the basis of inconclusive evidence

Strong: All I know is on the basis of inconclusive evidence

Belief-fallibilism is a commitment to anti-dogmatism. It holds that one (or any!) of your beliefs may be false, so you should root it out and correct it. The upshot is that one should hold beliefs in the appropriately tentative fashion, and face disagreement and doubts with seriousness.

Knowledge-fallibilism is a form of anti-skepticism. It holds, against the skeptic, that one does not need to eliminate all possible defeaters for a belief in order to have knowledge; one needs only to address the relevant defeaters. The knowledge-fallibilist contends that the skeptic proposes only the silliest and least relevant of possible defeaters of knowledge. We rebuke the skeptic by rejecting the idea that all possible defeaters are equally in need of response. Again, the knowledge-fallibilist holds that knowing that p is consistent with being unable to defuse distant skeptical defeaters; knowing that p rather requires only that the relevant defeaters have been ruled out.

Although these two varieties of fallibilism are propositionally consistent, they prescribe conflicting intellectual policies. Belief-falliblism yields the attitude that, as any of one's beliefs could be false, one must follow challenges wherever they lead. But knowledge-fallibilism holds that one needn't bother considering certain kinds of objections; it thereby condones the attitude that a certain range of challenges to one's beliefs may be simply dismissed.
