“Man is an engine, the motive power of which is the soul; and the greatest amount of work will not be accomplished by this engine for pay, or under pressure, or by the help of any kind of fuel which may be supplied by the ton. It will be done only when the will or the spirit of the creature is brought to its greatest strength by its own natural fuel, namely: the affections.”

–Maurice de Saxe, Marechal de France
