Prus called Spencer "the Aristotle of the 19th century" and wrote: "I grew up under the influence of Spencerian evolutionary philosophy and heeded its counsels, not those of Idealist or Comtean philosophy."
Prus l-ar fi numit pe Spencer "Aristotel al secolului al XIX-lea" si scrie : "Am crescut sub influenta filosofiei progresive spencieriene, tinand cont de sfaturile sale si nu cele ale idealistilor sau cele ale filosofiei lui Auguste Comte".
