""But, though the Church hath evermore from Holy Writ affirmed that the earth should be a wide-spread plain bordered by the waters, yet he [Magellan] comforted himself when he considered that in the eclipses of the moon the shadow cast of the earth is round; and as is the shadow, such, in like manner, is the substance." It was a stout heart - a heart of triple brass - which could thus, against such authority, extract unyielding faith from a shadow."

"The Koran abounds in excellent moral suggestions and precepts; its composition is so fragmentary that we can not turn to a single page without finding maxims of which all men must approve. This fragmentary construction yields texts, and mottoes, and rules complete in themselves, suitable for common men in any of the incidents of life."

"I have to deplore the systematic manner in which the literature of Europe has contrived to put out of sight our scientific obligations to the Mohammedans. Surely they can not be much longer hidden. Injustice founded on religious rancor and national conceit can not be perpetuated forever. … The Arab has left his intellectual impress on Europe, as, before long, Christendom will have to confess; he has indelibly written it on the heavens, as any one may see who reads the names of the stars on a common celestial globe."

"Every movement in the skies or upon the earth proclaims to us that the universe is under government."

"Time, to the nation as to the individual, is nothing absolute; its duration depends on the rate of thought and feeling."

"Four years after the death of Justinian, A.D. 569, was born at Mecca, in Arabia, the man who, of all others, has exercised the greatest influence upon the human race—Mohammed… To be the religious head of many empires, to guide the daily life of one third of the human race, may perhaps justify the title of a messenger of God."

"Vier Jahre nach dem Tode von Justinian, 569 n.Chr., wurde in Mekka, Arabien, der Mann geboren, der unter allen Männern den größten Einfluss auf die Menschheit gehabt hat."

"Der Koran fließt über von ausgezeichneten moralischen Empfehlungen und Geboten. Er ist so aufgebaut, dass wir nicht eine einzige Seite lesen können ohne auf Maximen zu stoßen, denen alle Menschen zustimmen müssen. Seine fragmentarische Einteilung führt zu Texten, Leitmotiven und Regeln, die in sich abgeschlossen sind in einer Weise, dass sie für den normalen Menschen in jeder Lebenslage zutreffen."
