”(…)those communities which included the greatest number of the most sympathetic members, would flourish best and rear the greatest number of offspring.” (Charles Darwin, The descent of man and selection in relation to sex, Vol. 1, New York: D. Appleton and Company, 1871, pp. 79)
”The slight corporeal strength of man, his little speed, his want of natural weapons, etc., are more than counterbalanced, firstly by his intellectual powers, through which he has, while still remaining in a barbarous state, formed for himself weapons, tools, etc., and secondly by his social qualities which lead him to give aid to his fellow-men and to receive it in return.” (Charles Darwin, The descent of man and selection in relation to sex, Vol. 1, New York: D. Appleton and Company, 1871, pp. 150-151)
