By this standard, the theories of Darwin and Einstein should never have been accepted. (John N. Gray)

The revolution in scientific ideas just mentioned is primarily logical. It is due to recognition that the very method of physical science, with its primary standard units of mass, space, and time, is concerned with measurements of relations of change, not with individuals as such.
