(1) Maxim of quantity -
Make your contribution as informative as is required:
'Excuse me, do you have the time?'
(2) Maxim of quality -
(a) Do not say that which you believe to be false:
'My God, I beseech thee, give me some proof of thy nonexistence!'
(b) Do not say that for which you lack adequate evidence:
'I find Maritain's thought unnacceptable and irritating. Thank God I've never read any of his books!'
(3) Maxim of relation -
'Can you give me a motorboat?'
'Why, you bet your life! I did my military service in Death Valley!'
(4) Maxim of manner -
Avoid obscurity of expression and ambiguitiy. Be brief and avoid unnecessary prolixity. Be orderly:
Mrs Slocombe (from 'Are You Being Served'):It's a wonder I'm here at all, you know. My pussy got soakin' wet. I had to dry it out in front of the fire before I left.
