Will v. Intellect ... or Reason v. Prejudice

In the immediately preceding post, my fellow Georgetown alum Robert Araujo criticizes the Iowa gay marriage decision--which was unanimous, and in which the court's opinion was written by the Republican-appointed chief justice--by deploying the distinction between "intellect" (good) and "will" (bad).

I applaud the decision, and I do so in terms of a different distinction:  between "reason" (good) and "prejudice" (bad).
