  Thenegativemovementwhichfilledtheeighteenthcenturyhadforitswatchwordontheeconomicsidetheliberationof

  Fromthisstateofoscillation,whichhasgiventothe19thcenturyitsequivocalandtransitionalaspect,theonlypossible

  Thesegeneralprinciplesaffecttheeconomicnolessthanotherbranchesofsocialspeculation;andwithrespecttothat

  Hence,too,itwillfollowthat,whateverusefulindicationsmaybederivedfromourgeneralknowledgeofindividualhuman
