Much of his work he did while confined to his bed. He was always an invalid, always obliged to take great care of himself, living constantly with death just before him, never idle a moment for fear his work would not be done. Probably no man ever lived who assailed the Church and the State with the same wit and keenness that was always at Voltaire's command; and yet in spite of this he managed to live comfortably, accumulate riches and die in peace.
Voltaire (1916)
