Christianity, by emphasizing discipline, reason, and the value of nature as such, became the rock on which empirical science was founded. Science arose and could arise only in a Christian civilization. The East, lacking this foundation, never became scientific. Science is not inimical to a Christian civilization, for it has flourished only in a Christian civilization. It has not flourished in a Buddhist civilization, nor amongst the Mohammedans, for the reason that a pantheistic civilization that confuses God and the world can never get hold of the world alone to study it scientifically. The Christian conception, on the contrary, makes God and the world distinct, and therefore make it possible for a man to study the universe as the universe. In doing this, man follows out the injunction of the Creator, Who commanded man to rule over the earth and subject it.
