The essay analyzes the word "Humanity" starting from its polysemic character, whose meaning may change according to historical periods and
cultural contexts. The author shows how the terms "humanity" and "human"
have always offered a battlefield for philosophy, while the concepts
of "inhumanity" and "dis-humanity" have been understood as constituting
factors of the same symbolic dimension of the human being. To this
first conceptual overlapping, the author adds also the difference between
human and "posthuman": this difference, in fact, characterizes the contemporary philosophical debate. Finally, the author focuses on the ideas
of humanity faced with the concept of "human nature" after the new perspectives opened by genetics and a criticism involving both humanistic
historicism and philosophical anthropology.
