All human history attests That happiness for man, - the hungry sinner! - Since Eve ate apples, much depends on dinner. ~Lord Byron, Don Juan, Canto XIII, stanza 99
Because men, compared to male chimps, have such relatively small testicles (large testicles indicate a species where many males mate, one after the other, with the same female), we might guess that promiscuous societies were uncommon in the immediate human past.
If Natur has gifted a man with powers of argeyment, a man has a right to make the best of 'em, and has not a right to stand on false delicacy, and deny that he is so gifted; for that is a turning of his back on Natur, a flouting of her, a slighting of her precious caskets, and a proving of one's self to be a swine that isn't worth her scattering pearls before.
Through error you come to the truth! I am a man because I err! You never reach any truth without making fourteen mistakes and very likely a hundred and fourteen.
O philosophy, life's guide! O searcher-out of virtue and expeller of vices! What could we and every age of men have been without thee? Thou hast produced cities; thou hast called men scattered about into the social enjoyment of life.
[Lat., O vitae philosophia dux! O virtutis indagatrix, expultrixque vitiorum! Quid non modo nos, sed omnino vita hominum sine et esse potuisset? Tu urbes peperisti; tu dissipatos homines in societatum vitae convocasti.]
I hold that if the Almighty had ever made a set of men that should do all the eating and none of the work, he would have made them with mouths only and no hands, and if he had ever made another class that he intended should do all the work and none of the eating, he would have made them without mouths and with all hands.
I have very carefully studied Islam and the life of its Prophet (PBUH). I have done so both as a student of history and as a critic. And I have come to conclusion that Muhammad (PBUH) was indeed a great man and a deliverer and benefactor of mankind which was till then writhing under the most agonising Pain.
