|Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring. The offspring, also, will thus have a better chance of surviving.
– Charles Darwin (1809-1882)
|Hereditary succession has no claim. For all men being originally equals, no one by birth could have the right to set up his own family in perpetual preference to all others for ever, and tho’ himself might deserve some decent degree of honours of his contemporaries, yet his descendants might be far too unworthy to inherit them.
– Thomas Paine (1737-1809)
