First, the individuals who would be most likely to benefit need to be identified, writes editorialist Sanford Markowitz, MD, PhD, from Case Western Reserve University, in Cleveland, Ohio. Then, it needs to be shown that certain persons reproducibly demonstrate high COX-2 expression in independent adenomas or cancers, because of genetic predisposition or environmental exposures. And third, the work of Dr. Chan and colleagues needs to be extended by demonstrating that prevention of colon adenomas by aspirin or COX-2 inhibitors also involves blocking the development of the highest COX-2–expressing lesions, he says.

It's true, as was just mentioned, that Davidson doesn't purport to offer a complete account of what determines the object of given responses. But we may well worry that the shared-cause requirement is so undiscriminating that it can seem motivated only if we elide, as Davidson sometimes seems to do, the difference between it and the requirement stated in terms of judgment.

如刚才提到的，Davidson并不试图提供一个对'什么规定了给出回应的对象'以完全说明，而我们可以恰当担心"对'被分享的原因'的必须"是如此难以识别出，以致仅当我们取消在它和根据判断所陈述的必须之间的区别时它才似乎是能被激发的，如Davidson有时似乎做的那样。

In reading Kelsen, however, one has to bear in mind that, when he refers to a 'norm', he is usually speaking elliptically: he is uttering a legal proposition which stands for a legal norm, in much the same way that a picture of a dog shows the dog but does not bark.

凯尔森将法律世界分成三层，层层剥茧、步步深入，但我们在阅读凯尔森的著作时必须注意：它言说的对象是不在场的，是隐藏在法律规则背后的，是必须经过思辨才能把握的。
