For Protestants, Diligence (or hard work) is one of the ways to please God. Max Weber (1864-1920) treats this in his work The Protestant Ethic and the Spirit of Capitalism. In his work "Anthropologie in pragmatischer Hinsicht", Immanuel Kant stated that of the capital sins sloth, cowardice and falsehood, the first one is the most despicable. However, he also sees this as a measure of self-protection of the individual, as long phases of hard work will lead a person to become tired, and to make short pauses between intervals of work. Without these pauses, the restles malice that is in the world would do a far greater amount of damage. In 1846, Louis Blanc wrote about the right to work. There was a financial crisis at the time, and many people were unemployed. The crisis led to the French Revolution of 1848.
