Democracy - Terry Pratchett quote

'In return, however,’ said the Patrician, ‘I must ask you not to upset Commander Vimes.’ He gave a little cough.  ‘More than necessary.’
‘I’m sure we can pull together, sir.’
‘Oh, I do hope not, I really do hope not. Pulling together is the aim of despotism and tyranny. Free men pull in all kinds of directions.’ 
He smiled. ‘It’s the only way to make progress.'  (TT)
