Already enough is known to show that the whole concept of the superiority of Western Christian civilization is one based on an arrogant ignorance of the rest of the world.

Man is occupied and has been persistently occupied since his separate evolution, with three kinds of struggle: first with the massive, unintelligent forces of nature, heat and cold, winds, rivers, matter and energy; secondly, with the things closer to him, animals and plants, his own body, its health and disease; and lastly, with his desires and fears, his imaginations and stupidities.

Knowledge that is not being used for winning of further knowledge does not even remain- it decays and disappears.
