Lem put into words the paradox of resuscitation form atoms in the book 'Dialogues' (1957), paradox unsolved untill today. There is followig problem : is X * an alive copy of dead person X - who has identical atomic structure - the same as X? The issue has already been considered in the past although in crude version by Lucretius. Lem's arguments against the possiblity of resuscitacion only intesify the power of paradox. It also appears with reference to cloning of human beings. Lem objected to such process. Identity of reproduced zygote is unclear and therefore reasonable resistance arises to human clonnig.
