QUÆRENS.. Yet there is a wide divergence between human beings themselves in all that pertains both to intellect and morals. We in Europe differ greatly from the tribes of Abyssinia and from the savages of the Oceanic Isles. What people do you take as a type of the highest degree of intelligence on the Earth? [Sidenote: The Arabs and their intelligence.] LUMEN. The Arabs. They are capable of producing their Keplers, their Newtons, their Galileos, their Archimedes, their Euclids, their D'Alemberts. Besides, they sprang from those primitive hordes whose roots reach down to the bed rock of humanity. But it is not necessary to choose a people for a type. It is better to consider modern civilisation as a whole. Nor is there so marked a distance as you appear to suppose, between the brain capacity of a negro and that of the Latin race. However, if you insist upon a comparison, I can assure you that the men of the planet of Virgo are almost on a par intellectually with the Scandinavians. [Sidenote: Vital difference between Virgo and the Earth.] The most vital difference which exists between their world and the Earth, _is the absence of sex_. Neither plants, animals, nor human beings have sex. Generation is effected spontaneously, as the natural result of the union of certain physiological conditions in some of the fertile isles of this planet, man not being formed in the womb of his mother as upon earth. It would be useless to explain the process, to one whose earthly faculties prevent him comprehending the facts of a world distinctly different from his own. It results from this organic arrangement, that marriage in any form does not exist in this world, and that the friendships between human beings are never mixed with the carnal desires, which are inevitably manifested on the Earth between people of different sexes, even when the attraction is most pure. Probably you will remember that during the protozoic period, the inhabitants of the Earth were all deaf, dumb, and sexless. The division into sexes took place much later in the history of Nature both among animals and plants.
