sottise

Il y a à parier que toute idée publique, toute convention reçue, est une sottise, car elle a convenu au plus grand nombre.

It is safe to wager that every public idea and every accepted convention is foolish because it has suited the majority.

La sottise, l’erreur, le péché, la lésine / Occupent nos esprits et travaillent nos corps,

Foolishness, error, sin, miserliness / Occupy our minds and work on our bodies,
