… A hundred times I wished to kill myself, but my love of life persisted. This ridiculous weakness is perhaps one of the most fatal of our faults. For what could be more stupid than to go on carrying a burden that we always long to lay down? To loathe, and yet cling to, existence? In short, to cherish the serpent that devours us, until it has eaten our hearts?

– The Old Woman’s Story, Candide (Voltaire)
