This article poses the question of ‘the human’ whose security it is 'human security'’s ambition to advance and preserve. New research and new reflexion—by anthropologists, psychologists, philosophers and others—suggests that the humanity of humans is, as with most phenomena, finite, that the definition or concept that regulates it has limits, that these limits have become more tangible, and that, as a consequence, a new look at ‘human security’ is warranted.
