not be able to originate, but we can guide. The processes of evolution are in
constant and spontaneous activity, some pushing towards the bad, some

checking the former and giving free play to the latter. We must distinguish
clearly between our power in this fundamental respect and that which we
also possess of ameliorating education and hygiene. It is earnestly to be
hoped that inquiries will be increasingly directed into historical facts, with
the view of estimating the possible effects of reasonable political action in
the future, in gradually raising the present miserably low standard of the
human race to one in which the Utopias in the dreamland of philanthropists
may become practical possibilities.
