political science, our history, our philosophy, and even our religion.
Science declared that 'the survival of the fittest' was a law of nature,
though nature has condemned to extinction the majestic animals of the
saurian era, and has carefully preserved the bug, the louse, and the
spirochaeta pallida.

We dined as a rule on each other;
What matter? the toughest survived,

is a fair parody of this doctrine. In political science, by a portentous
snobbery, the actual evolution of European government was assumed to be
in the line of upward progress. Our histories contrasted the benighted
condition of past ages with the high morality and general enlightenment
of the present. In philosophy, the problem of evil was met by the
theory that though the Deity is not omnipotent yet, He is on His way to
become so. He means well, and if we give Him time, He will make a real
success of His creation. Human beings, too, commonly make a very poor
thing of their lives here. But continue their training after they are
dead and they will all come to perfection. We have been living on this
secularised idealism for a hundred and fifty years. It has driven out
the true idealism, of which it is a caricature, and has made the deeper
and higher kind of religious faith abnormally difficult. Even the hope
of immortality has degenerated into a belief in apparitions and voices
from the dead.

Nature knows nothing of this precious law. Her figure is not the
vertical line, nor even the spiral, but the circle--the vicious circle,
according to Samuel Butler. 'Men eat birds, birds eat worms, worms eat
men again.' Some stars are getting hotter, others cooler. Life appears
at a certain temperature and is extinguished at another temperature.
