Ethics

For an argument in favor of the frormer, see Eric Johnson's A Populist Manifesto for Learning the Law.  Abstract:

In this article, I examine the questions above and conclude that there are intelligent, well-formed arguments for taking a more populist approach to teaching law. The pedagogical view I present in this article can be summed up as three interrelated propositions: 

? Law professors should cease to regard as sacrosanct the process of learning law through the reading of judicial opinions. 
? Law professors should let go of old taboos about student study-aids and other shortcuts to learning. 
? Law professors should strive, insofar as possible, to make learning doctrine easier and less time-consuming. 

In its briefest form, my argument is this: We lack good rationales for insisting on more difficult modes of learning, and in the absence of a convincing case to the contrary, we ought to try to make learning the law easier. All things being equal, the easier way is the better way, because the easier we make it to learn, the more we will be able to teach.

For the latter, see the comments to this post by Lyrissa Lidsky at Prawfsblawg.
