A visitor from before the 20th century would be stunned to see the extent to which the world is now dominated by materialism. It has many dimensions.
Keanu Reeves in The MatrixOne is scientific materialism — considering everything, including the human mind, to be just matter. Another is financial materialism, assuming money to be what defines everything else.
That visitor from an earlier time would be stunned to see how much we understand the world using monetary measures. Finance has come to be considered the first reality, not defined by, or reflecting, reality. The cart has been put before the horse.
