"Necessity is the plea for every infringement of human freedom. It is the argument of tyrants; it is the creed of slaves."
-- British Prime Minister "The Right Honourable" William Pitt the Younger, stated on the floor of the House of Commons November 18th 1783
That may have influenced a later epigram by Brit WH Auden:
“The tyrant’s device: Whatever is possible is NECESSARY.”
