Check out this fabulous little essay by Jonah Goldberg on the virtues of a dead Constitution.
Here's a nice bit:
We’ve all heard about how great living constitutions are. The most extreme, but essentially representative, version of this “philosophy” can be found from the likes of Mary Frances Berry or the Los Angeles Times’s Robert Scheer. They matter-of-factly claim that without a “living” constitution, slavery and other such evils would still be constitutional. This is what leading constitutional legal theorists call “stupid.” The constitutionality of slavery, women’s suffrage and the like were decided by these things called the 13th, 14th and 15th Amendments. Also, contra feminists, women got the vote not through a living constitution but by the mere expansion of the dead one — via the 19th Amendment.
