Full Idea
All men accept the most rigorous morality when there is no question of putting it into practice.
Gist of Idea
Everyone is devoted to morality, if they don't have to implement it
Source
Simone Weil (Lect 3: Politics and Society [1933], p.129)
A Reaction
Presumably this ranges from deliberate hypocrisy to a failure to know ourselves. There is also the question of scope. The mafia seem to be devoted to morality, but only within their family.
