▁that ▁' [ a ] s ▁individuals ▁express ▁their ▁life , ▁so ▁they ▁are . ▁Hence ▁what ▁individuals ▁are ▁depends ▁on ▁the ▁material ▁conditions ▁of ▁their ▁production ', ▁he ▁also ▁bel ieves ▁that ▁human ▁nature ▁will ▁condition ▁( ag ain st ▁the ▁background ▁of ▁the ▁product ive ▁forces ▁and ▁relations ▁of ▁production ) ▁the ▁way ▁in ▁which ▁individuals ▁express ▁their ▁life . ▁ ▁History ▁involves ▁' a ▁continuous ▁transformation ▁of ▁human ▁nature ', ▁though ▁this ▁does ▁not ▁mean ▁that ▁every ▁aspect ▁of ▁human ▁nature ▁is ▁wh olly ▁variable ; ▁what ▁is ▁transformed ▁need ▁not ▁be ▁wh olly ▁transformed . ▁ ▁Marx ▁did ▁critic ise ▁the ▁t endency ▁to ▁' transform ▁into ▁et ernal ▁laws ▁of ▁nature ▁and ▁of ▁reason , ▁the ▁social ▁forms ▁spring ing ▁from ▁your ▁present ▁mode ▁of ▁production ▁and ▁form ▁of ▁property '. ▁For ▁this ▁reason , ▁he ▁would ▁likely ▁have ▁wanted ▁to ▁critic ise ▁certain ▁aspects ▁of ▁some ▁accounts ▁of ▁human ▁nature . ▁ ▁Some ▁people ▁believe , ▁for ▁example , ▁that ▁humans ▁are ▁naturally ▁self ish ▁- ▁Im manuel ▁Kant ▁and ▁Thomas ▁Hob bes , ▁for ▁example . ▁( B oth ▁Hob bes ▁and ▁Kant ▁thought ▁that ▁it ▁was ▁necessary ▁to ▁const rain ▁our ▁human ▁nature ▁in ▁order ▁to ▁achieve ▁a ▁good ▁society ▁- ▁Kant ▁thought ▁we ▁should ▁use ▁rational ity , ▁Hob bes ▁thought ▁we ▁should ▁use ▁the ▁force ▁of ▁the ▁state ▁- ▁Marx , ▁as ▁we ▁shall ▁see , ▁thought ▁that ▁the ▁good ▁society ▁was ▁one ▁which ▁allows ▁our ▁human ▁nature ▁its ▁full ▁expression .) ▁
