For me, Scalia was a terrible judge. And he was terrible because his decisions relied upon intellectual behaviors that were dominant in history at least one century prior to his time on the bench. He used an a-priori format, syllogistic reasoning, formalism, and took positions about language that had been badly discredited in the time in which he lived. In fact, he is known for inventing the concept of original meaning, which was always an intellectually flawed idea. He reminded me of the character "Dr. Zaius" in the 1968 movie, Planet of the Apes, because of these behaviors.
