There are some good reasons to think that future historians will characterize twentieth century century of secularism. As century began, Nietzsche's declaration that God is dead, made some years earlier, was still reverberating. Three years into century, Bertrand Russell's famous essay, A Free Man's Worship, was published.1 The essay is widely interpreted a powerful renunciation of religion in favor of an ethical humanism. Then came existentialism. Despite its religious beginnings in Kierkegaard and Buber, existentialism established itself in twentieth century a thoroughly secular philosophy. As David Cooper puts it, existentialism as defined by Sartre, made notion of a religious existentialist a virtual contradiction..2 While existentialism is no longer an influential philosophy, its secular messages have been well absorbed. However, it remains to be seen whether secular trend will continue into new millennium. According to some observers, it is too hasty to assume that it will. Indeed, Gianni Vattimo claims that end of twentieth century has witnessed a to religion.3 Given standard view of existentialism, it may be taken for granted that if there is a return to religion then it cannot be via existentialism. The trouble is that philosophy has habit of demonstrating that what is taken for granted turns out to be otherwise. At least, wish to demonstrate that this is so in case of existentialism. Specifically, aim of this essay is to show that philosophy of Emmanuel Levinas is essentially an existentialist philosophy and if so, then, far from being a dead end, existentialism could well be main route for a return to religion. Levinas' account of subjectivity is discussed in Section I. In Section II, defend claim that Levinas' philosophy of subjectivity is essentially existentialist. In Section III, religiousness of that philosophy is explored. In his various writings, Levinas employs term l'Autrui, often translated the Other, to refer to one's fellow human beings, indefinite neighbors, strangers, widows and orphans, and term 1 'Autre, often translated the other, to refer to what lies beyond totality that is one's own being, beyond what constitutes one's essence, a realm to which Other belongs. The world that one knows is called the le dit, because all things in that world are known through what is said about them, through our own thematization or conceptualization of them. The realm of other is called the saying, le dire, because we are aware of it only through what it says to us rather than through our thematization. As a totality, belong to world of said, having an essence that can be thematized, a being that can be conceptualized; for instance, thematized and conceptualized in science or in traditional philosophy. However, this is utterly devoid of any subjectivity. In response to this, in Totality and Infinity, Levinas embarks on a phenomenological journey, tracing subjectivity of I.4 As is case with any classical phenomenology, Levinas begins with mundane experiences of I, showing that acquires its unique identity, or its unicity, by separating or isolating itself from what is not itself in activity of enjoyment. It is in that one is aware of one's own happiness and unhappiness, thus aware of one's own ipseity. For Levinas, enjoyment . . . is (TI, 117) and isolation is structure of unicity of I. The phenomenology of allows Levinas to conclude that self sufficiency of enjoying measures egoism or ipseity of Ego and same. Enjoyment is a withdrawal into oneself, an involution (TI, 118). In enjoyment, see all things in terms of my own being because in it I am absolutely for myself (TI, 134). Yet, in very process of enjoying, come to be aware that am much more than my own enjoyment. …
