QUOTE: "TO LISTEN IS AN EFFORT AND JUST TO HEAR IS NO MERIT. A DUCK HEARS ALSO".

I think that the quote above means that listening and hearing are two different things. Listening is a mental process involving paying attention to and make sence of what is being heard. Hearing is a physiological process that involves the vibration of sound waves on the eardrums.I agree with this quote because whun people hear they dont take in any information. But when you listen you pay attention to and make sence of what is being heard.
