Morality, like art, means drawing a line someplace.
The phrase above is attributed to Oscar Wilde at websites such as like "Goodreads" and "The Quotations Page". But QI has found no substantive evidence linking the saying to Wilde. Instead, there is another similar saying that was written by the English author, journalist, and critic Gilbert Keith Chesterton in "The Illustrated London News" in May 1928:
Art, like morality, consists of drawing the line somewhere.
Interestingly, the positions of the terms "art" and "morality" were switched in Chesterton's original statement. To learn more about the history of this saying you may visit the Quote Investigator website:http://quoteinvestigator.com/2014/07/20/drawing/
