Voltaire"A hundred times I was upon the point of killing myself; but still loved life. This ridiculous foible is perhaps one of our most fatal characteristics, for is there anything more absurd than to wish to carry continually a burden which one can always throw down? To detest existence and yet to cling to one's existence? In brief, to caress the serpent which devours us, till he has eaten our very heart?"
- Candide by Voltaire
