"Materialism in its literal sense is long since dead. But its place has been taken by other philosophies which represent a virtually equivalent outlook. The tendency today is not to reduce everything to manifestations of matter—since matter now has only a minor place in the physical world—but to reduce it to manifestations of the operation of natural law... laws of the type prevailing in geometry, mechanics, and physics which are found to have this common characteristic—that they are ultimately reducible to mathematical equations. ...[T]hey are laws which, unlike human law, are never broken. It is the belief in the universal dominance of scientific law which is nowadays generally meant by materialism."
