John Stuart Mill,
Auguste Comte and Positivism
“ When we consider that the united power of the whole human race cannot reproduce a species once eradicated—that what is once done, in the extirpation of races, can never be repaired; one can only be thankful that amidst all which the past rulers of mankind have to answer for, they have never come up to the measure of the great regenerator of Humanity; mankind have not yet been under the rule of one who assumes that he knows all there is to be known, and that when he has put himself at the head of humanity, the book of human knowledge may be closed. ”
