African theologian David DeBruyn offers a clear and important biblical reason to reject populist objections to special knowledge.

God has so made the world and limited man that we each need to specialise in some domain of human life. We need some to give themselves to knowing the human physiology, so as to become experts in medicine and healing. We need some to give themselves to the physics of motion, so as to become engineers. We need some to give themselves to understanding the market, so as to become experts in economics. And we need some to give themselves to the study of music, painting, poetry, literature and architecture, so as to become experts in the arts. No one can master all the realms of knowledge in the short lifespan appointed to us. It is one of God’s mercies to the world: forcing interdependence, trade, and learning.
