For me, that aspect of my job has been tremendously rewarding. My colleagues are brilliant people with wide-ranging and impressive backgrounds. Sometimes we approach issues from quite different perspectives, or with different priorities or values in mind. Yet we always listen to each other, and our conferences are marked by vibrant debate and discussion. Our commitment to this process, in my view, is the principal mechanism for assuring that we will reach the right decision as often as possible.
The case for originalism is quite different. It is that in our system of government, written laws (statutes and constitutional provisions) are supposed to provide stable rules around which society can organize itself. Such rules are presumed to remain in place until amended or repealed by the people. Originalism is aimed at preserving the laws enacted by the people or their representatives, and at preserving stability and predictability in our legal system.
