They tend to become a purely human basis of nature, morality, and politics.

If each one of us adds something to the common weal in the domain of science, or art, or morality, the reason is because long series of generations have lived, worked, thought, and suffered before us. The science which you honour to-day has been created by the patient labours of our predecessors.
