. ▁Position ▁( 1 ) ▁is ▁hard ▁determin ism , ▁and ▁position ▁( 2 ) ▁is ▁libert arian ism . ▁The ▁position ▁( 1 ) ▁of ▁hard ▁determin ism ▁adds ▁to ▁the ▁table ▁the ▁cont ention ▁that ▁D ▁implies ▁F W ▁is ▁un true , ▁and ▁the ▁position ▁( 2 ) ▁of ▁libert arian ism ▁adds ▁the ▁cont ention ▁that ▁F W ▁implies ▁D ▁is ▁un true . ▁Position ▁( 9 ) ▁may ▁be ▁called ▁hard ▁in compat ibil ism ▁if ▁one ▁interpre ts ▁? ▁as ▁meaning ▁both ▁concepts ▁are ▁of ▁dub ious ▁value . ▁Comp at ibil ism ▁itself ▁may ▁occup y ▁any ▁of ▁the ▁nine ▁positions , ▁that ▁is , ▁there ▁is ▁no ▁logical ▁contradiction ▁between ▁determin ism ▁and ▁free ▁will , ▁and ▁either ▁or ▁both ▁may ▁be ▁true ▁or ▁false ▁in ▁principle . ▁However , ▁the ▁most ▁common ▁meaning ▁attached ▁to ▁compat ibil ism ▁is ▁that ▁some ▁form ▁of ▁determin ism ▁is ▁true ▁and ▁yet ▁we ▁have ▁some ▁form ▁of ▁free ▁will , ▁position ▁( 3 ). ▁ ▁Alex ▁Ros enberg ▁makes ▁an ▁ext rap olation ▁of ▁physical ▁determin ism ▁as ▁infer red ▁on ▁the ▁macro scop ic ▁scale ▁by ▁the ▁behaviour ▁of ▁a ▁set ▁of ▁dom ino es ▁to ▁neural ▁activity ▁in ▁the ▁brain ▁where ; ▁" If ▁the ▁brain ▁is ▁nothing ▁but ▁a ▁complex ▁physical ▁object ▁whose ▁states ▁are ▁as ▁much ▁govern ed ▁by ▁physical ▁laws ▁as ▁any ▁other ▁physical ▁object , ▁then ▁what ▁goes ▁on ▁in ▁our ▁heads ▁is ▁as ▁fixed ▁and ▁determined ▁by ▁prior ▁events ▁as
