“If the whole earth is infinitely small in comparison with the sphere of the stars, what is man compared with all these created beings? How, then, could any one of us imagine that these things exist for his sake and benefit, and that they are his tools! This is a result of an examination of the corporeal beings: how much more so will be the result of an examination of the Intelligences!”

Mishneh Torah (c. 1180)
Context: When a man reflects on these things, studies all these created beings, from the angels and spheres down to human beings and so on, and realizes the divine wisdom manifested in them all, his love for God will increase, his soul will thirst, his very flesh will yearn to love God. He will be filled with fear and trembling, as he becomes conscious of his lowly condition, poverty, and insignificance, and compares himself with any of the great and holy bodies; still more when he compares himself with any one of the pure forms that are incorporeal and have never had association with any corporeal substance. He will then realize that he is a vessel full of shame, dishonor, and reproach, empty and deficient.

Book XLII: Ch. 18: A summary of the changes which have occurred around the globe in my lifetime
Mémoires d'outre-tombe (1848 – 1850)
Context: How small man is on this little atom where he dies! But how great his intelligence! He knows when the face of the stars must be masked in darkness, when the comets will return after thousands of years, he who lasts only an instant! A microscopic insect lost in a fold of the heavenly robe, the orbs cannot hide from him a single one of their movements in the depth of space. What destinies will those stars, new to us, light? Is their revelation bound up with some new phase of humanity? You will know, race to be born; I know not, and I am departing.

Alphonse de Lamartine, Histoire de la Turquie (1854), Vol. I, pp. 276-277
Context: Never has a man set for himself, voluntarily or involuntarily, a more sublime aim, since this aim was super human; to subvert superstitions which had been imposed between man and his Creator, to render God unto man and man unto God; to restore the rational and sacred idea of divinity amidst the chaos of the material and disfigured gods of idolatry, then existing. Never has a man undertaken a work so far beyond human power with so feeble means, for he Muhammad had in the conception as well as in the execution of such a great design, no other instrument than himself and no other aid except a handful of men living in a corner of the desert. Finally, never has a man accomplished such a huge and lasting revolution in the world, because in less than two centuries after its appearance, Islam, reigned over the whole of Arabia, and conquered, in God's name, Persia, Khorasan, Transoxania, Western India, Syria, Egypt, Abyssinia, all the known continent of Northern Africa, numerous islands of the Mediterranean Sea, Spain and part of Gaul.
If greatness of purpose, smallness of means, and astounding results are the three criteria of human genius, who could dare to compare any great man in modern history with Muhammad? The most famous men created arms, laws and empires only. They founded, if anything at all, no more than material powers which often crumbled away before their eyes. This man moved not only armies, legislations, empires, peoples and dynasties, but millions of men in one-third of the then inhabited world; and more than that, he moved the altars, the gods, the religions, the ideas, the beliefs and souls... his forbearance in victory, his ambition, which was entirely devoted to one idea and in no manner striving for an empire; his endless prayers, his mystic conversations with God, his death and his triumph after death; all these attest not to an imposture but to a firm conviction which gave him the power to restore a dogma. This dogma was twofold, the unity of God and the immateriality of God; the former telling what God is, the latter telling what God is not; the one overthrowing false gods with the sword, the other starting an idea with words.
Philosopher, orator, apostle, legislator, warrior, conqueror of ideas, restorer of rational dogmas, of a cult without images; the founder of twenty terrestrial empires and of one spiritual empire, that is Muhammad. As regards all standards by which human greatness may be measured, we may well ask, is there any man greater than he?
