I have a strong opinion on people who pronounce their wisdom.
If anyone is currently telling you they are wise or telling you that they have some wisdom on a subject for you (of their own), they are currently not being wise. I am certainly guilty of this myself as well, perhaps even now. That doesn’t mean the self-proclaimed “wisdom” people have to say isn’t valuable to you necessarily. It does mean that their definition of the world isn’t the same as mine, and I think I’ve got a pretty good handle on it:
My definition is different from any dictionary’s definition. I will specify my definition: Wisdom is more about knowing what you don’t know than it is about knowing about what you do know.
I will cite a source to back up my opinion on this matter from a perhaps fictional character (a well-known fact is that he may have never lived and been a character Plato invented) that said what I assert are many wise things: “I am the wisest man alive, for I know one thing, and that is that I know nothing.” Socrates: (Plato’s Apology)
