by Thomas Hurka.
On the theoretical side, the side of our beliefs, we achieve more theoretical perfection the more knowledge we have. The more we understand the world, and ourselves, and our place in the world, the better and more choiceworthy our lives. Of course, not all knowledge has equal value. Knowing the co-stars in some 1930s movie is not as important as knowing a fundamental law of the universe, or understanding the workings of a friend's personality. We need a test for the best knowledge, and I suggest [1.] it is the most organized or systematic knowledge, with general principles unifying and explaining derived particulars. [End of 1.] This is most clearly present when we grasp a whole scientific theory from first principles down to particular explanations. But it is also present in interpersonal understanding and even the craft knowledge of skilled artisans.
1 appears too vague and imprecise to me. What exactly does Prof. Hurka mean?
