Posthumanism is the subject of our epoch. We address perhaps the most common critique of Posthumanism: that as archaeologists we could never be non-anthropocentric; that the central position of human beings to our discipline means they must always take centre stage. This paper wants to study the situation of individuality in posthuman worlds of scifis like Gibson's Neuromancer and Ishigurou's Klara and the Sun. it will try to clarify that with the emergence of posthumanism, individualism is not going to be weakened It refers precisely on humanism at first and then tries to bring clues from posthuman writers like Braidotti and Badmington to clarify the concept of posthumanism.Here this paper will try to study morality and ethics in the sci fic world in which human and robots cooperate to save humans' life.it can be said that in sci fic human being is the central figure still and sentient robots are human's assistant and follower agents. There should be a lot of studies in the field like posthumanism and AI.
