developments in scientific thought since the seventeenth century have contributed to the exorcism

of inertia to explain their action; second, the Darwinian theory
of evolution with its emphasis on chance, waste and the apparent «impersonality»
of natural selection; third, the laws
of thermodynamics (and particularly the second law) with the allied cosmological interpretation that our universe is running out
of energy available to sustain life, evolution and
human consciousness; fourth, the geological and astronomical disclosure
of enormous tracts

of all, the suspicion that mind may be explained exhaustively in terms
