I have already indicated to you the meaning of the word religion, as applied to Islam. The truth is that Islam is not a Church. It is a State conceived as a contractual organism long before Rousseau ever thought of such a thing, and animated by an ethical ideal which regards man not as an earth-rooted creature, defined by this or that portion of the earth, but as a spiritual being understood in terms of a social mechanism, and possessing rights and duties as a living factor in that mechanism.
