Our world, so we see and hear on all sides, is drowning in materialism, commercialism, consumerism. But the problem is not really there. What we ordinarily speak of as materialism is a result, not a cause. The root of materialism is a poverty of ideas about the inner and the outer world. Less and less does our contemporary culture have, or even seek, commerce with great ideas, and it is that lack that is weakening the human spirit. This is the essence of materialism. Materialism is a disease of the mind starved for ideas.
