“When goodness appears openly, it is no longer goodness, though it may still be useful as organized charity or an act of solidarity. Therefore: “Take heed that ye do not your alms before men, to be seen of them.” Goodness can exist only when it is not perceived, not even by its author; whoever sees himself performing a good work is no longer good, but at best a useful member of society or a dutiful member of a church. Therefore, “Let not thy left hand know what they right hand doeth.”

Hannah Arendt Human Condition
