Knowledge is the death of another knowledge, which is why we unlearn and relearn. You cannot relearn what you have not previously learned. It simply means that you cannot store new food in a dirty environment.
This is where the sentence LEARN, UNLEARN AND RELEARN, becomes lucid. Knowledge is very key, having a command of language is also very important, which is the ability to share, teach and influence another person with the wisdom one has. A knowledgeable man without the command of language cannot share anything.
Thanks for sharing
Yes, I agree, sometimes you need the command of a certain language to share knowledge, if not, an audience might not even understand the knowledge a potential creator aims to pass across
