This memorial essay examines the philosophical legacy of Emmanuel Levinas through an analysis of his autobiographical work "Signature" from *Difficult Freedom*. Using Levinas's own interpretive methodology derived from M. Chouchani's contextual interpretation of Talmudic texts, the author explores multiple meanings of "signature" as they relate to Levinas's intellectual development and ethical philosophy. The study traces Levinas's biographical journey from Lithuanian Jewish learning through his encounter with Western philosophy via Husserl and Heidegger, culminating in his captivity during Nazi Germany and subsequent development of an ethics-first philosophy. The analysis demonstrates how Levinas's "presentiment and memory of Nazi horror" fundamentally shaped his critique of Western totalistic thinking and his development of an alternative philosophical framework grounded in face-to-face ethical relationships with the Other. Through examination of Levinas's concept of time, consciousness, and moral responsibility, the paper argues that his work represents a successful translation of Hebrew biblical ethics into philosophical discourse while simultaneously rescuing Western philosophy from its totalitarian implications. The study concludes that Levinas's legacy lies in his insistence that all authentic philosophy must begin with the ethical moment of interpersonal encounter, thereby establishing ethics as first philosophy rather than a derivative concern.
