Wellllll . . . I'm inclined to agree more with CO on this one, Marv. Learning "the law" and how to practice it are two different things. Think of the law as a language . . . you learn the rules of syntax and the content of words, phrases and idioms, which become tools for your use. How you use those tools to fashion communications can lead one to be a poet, lyricist, novelist, journalist, teacher, parent, physician, philosopher, theologian or any other number of imaginative or creative things . . . or you can become a rote repeater of others' thoughts, bully or a gossip . . . or you might not learn any of the tools sufficiently to put them to good use and become a prolific liar because you don't know any better and you just want what you want.
The law is much the same way. Concepts captured in the law as statutes or case law precedent provide practitioners with tools to apply creatively to the facts that their clients' cases present to them. Lawyers who learn to use the law with horizontal (lateral) creativity can be highly effective contributors in their community (and very successful financially as well). Those few who master the tools of the law to use them both with horizontal and vertical creativity can move nations.
