“A human enemy does not push us toward the path of progress nearly as forcefully and accurately as our other great and mysteriously enchanted adversary - nature.
The internal social struggle that the individualist takes as the only possible and unquestionably necessary engine of progress in reality appears rather as its barrier. It wastes energy and dissipates the creative attention of men.
Man's struggle with nature - the main and universal engine of progress - is entirely devoid of such detrimental side effects.
Progress may be accomplished with the greatest speed and energy, the greatest versatility and harmony, only in a society that would have comradely cooperation as its form and the whole of humanity as its limit. There the forces of development will become infinite.”
