Hello @knowledgefruit.

Knowledge can flow in different streams, for example we can learn from a book, we can learn in a university based on the different professors that transmit us knowledge, but really if we do not execute that knowledge in something materialized we are not doing anything.

Now we can acquire knowledge through practice, that is to say, we can learn from day to day life, with the popular knowledge of the people, when we learn and obtain knowledge in this way, it is not necessary to demonstrate that knowledge for the simple reason that we have learned it from practice, on the other hand when we learn theoretical knowledge it is necessary to materialize it.

I had not read your posts before, they fascinate me because I like philosophy, you have one more follower, I hope to continue reading more of your excellent content, thanks for sharing.
