Des gueules, des gueules partout. L’homme s’étend. L’homme est le cancer de la terre.
Faces, faces everywhere. Mankind is spreading. Mankind is the cancer of the earth.
E.M. Cioran, De l’inconvénient d’être né (The Inconvenience of Being Born, 1977)
Perhaps “Mankind metastasizes.” would flow better with the cancer metaphor?
