▁that ▁before ▁f ission ▁there ▁was ▁one ▁am o eb a ▁( call ▁it ▁A ), ▁but ▁what ▁has ▁happened ▁to ▁it ? ▁It ▁has ▁not ▁died , ▁for ▁death ▁is ▁a ▁bi ological ▁state , ▁and ▁there ▁are ▁no ▁dead ▁am o eb ae ▁lying ▁around ▁after ▁the ▁f ission ! ▁In ▁fact , ▁there ▁is ▁more ▁life ▁after ▁the ▁f ission ▁than ▁there ▁was ▁before , ▁i . e . ▁two ▁live ▁am o eb ae ▁instead ▁of ▁just ▁one . ▁Has ▁A ▁somehow ▁ceased ▁to ▁exist ▁without ▁dying ? ▁Is ▁A ▁still ▁around , ▁and ▁identical ▁with ▁either ▁B ▁or ▁C ? ▁It ▁cannot ▁be ▁identified ▁with ▁both ▁B ▁and ▁C , ▁for ▁identity ▁is ▁a ▁trans itive ▁relation , ▁and ▁B ▁is ▁certainly ▁not ▁the ▁same ▁am o eb a ▁as ▁C . ▁Yet , ▁the ▁f ission ▁was ▁symmet rical , ▁so ▁neither ▁B ▁nor ▁C ▁has ▁any ▁more ▁or ▁less ▁claim ▁to ▁be ▁A ▁than ▁the ▁other . ▁This ▁is ▁the ▁problem . ▁We ▁seem ▁to ▁be ▁forced ▁to ▁say ▁that ▁A ▁has ▁ceased ▁to ▁exist , ▁but ▁the ▁m . o . ▁view ▁provides ▁us ▁with ▁another ▁option , ▁consistent ▁with ▁all ▁of ▁the ▁above ▁consider ations . ▁The ▁m . o . ▁view ▁is ▁that ▁there ▁were ▁two ▁distinct ▁but ▁coinc ident ▁am o eb ae ▁before ▁f ission , ▁occup ying ▁the ▁same ▁body ▁of ▁matter , ▁but ▁which ▁diver ge ▁upon ▁f ission ▁into ▁the ▁same ▁two ▁distinct , ▁but ▁no ▁longer ▁coinc
