“Knowledge speaks, but Wisdom listens.” Jimi Hendrix
“A Wise person knows that there is something to learn from everyone” – Poster Quote (Not sure the originator)
The first is one of my favourite quotes, and one I tend to adhere to as much as possible. Mainly because it speaks so many truths. I’m an avid listener rather than a talker (mainly because I hate the sound of my own voice :D), to spread knowledge is great but to broaden the horizons of your own knowledge is much is greater, knowledge is power after all!
I slightly disagree with the second; I would say a knowledgeable person knows there is something to be learned from everyone. Where-as a wise person would know how to use that information to either aide themselves or others with the new acquired information. But yes you can learn so much from other people, with just a little in depth observation, whether in conversation, watching them perform an act or just in a more general sense.
If Knowledge is information or a tool, then Wisdom is the understanding and application of said information or the craft within which you use said tool.
Unfortunately we can gain a lifetime of knowledge, yet never see the wisdom in it.
