The responsible subject in the global age.

The first thesis of this article is that the concept of responsibility takes on an unprecedented meaning in the twentieth century resulting from the emergence of a new dimension of the other: to be responsible comes to mean not just to account for oneself in relation to the other, but also to take the other into account, to take care of the other-what I call responsibility towards (the other). The main reason for this change consists in the emergence of global risks and the necessity, as underlined by Hans Jonas, to be responsible for the destiny of the world and future generations. The problem, as explored in the article's second thesis, is that this implies the existence of a subject who is capable of responsibility.
