Otherness and human embryo: the face as ethics demand host of other

In this article, we will discuss the themes of otherness and of the human embryo. From the ethical point of view, we show that the human embryo carries absense, has a face that needs protection and care in their existential condition. We divide the article into three points: first, we present the embryo as having life from conception, when it comes down to the moment of human existence. Later, reflecting on the category face as ethical requirement that expresses the imperative "thou shall not kill", according to philosopher Emmanuel Levinas's perspective. Finally, we argue that the human embryo, given their vulnerable condition, expresses the inordinate other as other, ie, the absolute otherness that begs needs and responsible acceptance and unconditional.
