I like this:
“Perception will not be our driver,because reality ultimately takes over from perception and it’s reality we rely on in establishing our record. (Graeme Samuel in discussing his time as Chairman of the Australian Competition and Consumer Commission 12.06.11.)
I believe we should constantly seek after our perception of the truth, uninfluenced by whatever the conventional wisdom may be. In pursuing a point, don’t get angry or rude,but just keep hammering away at what you believe to be true. Sir Gustav Nossal talks of “sweet reason”.
Beware of being dogmatic and remember the saying (attributed to J.M. Keynes and/or Einstein)- “When the facts change, I change my mind – what do you do, sir?”
