The whole analogy of natural operations furnishes so complete and
crushing an argument against the intervention of any but what are
termed secondary causes, in the production of all the phenomena of the
universe; that, in view of the intimate relations between Man and the
rest of the living world, and between the forces exerted by the latter
and all other forces, I can see no excuse for doubting that all are
co-ordinated terms of Nature's great progression, from the formless
to the formed--from tne inorganic to the organic--from blind force to
conscious intellect and will.
