The ideas are creations of the maind. Is a gesture from inside to outside. In this way, the opposite to learn is to create ideas. To create is to make something from nothing. An idea is always absolutly original, unique, because it comes from the interior of an individual mind (also unique).
Creation of ideas is one of the most important things in human life, that is, a man is not a man without ideas. Thats why William Morris talked about the need of creative jobs for all the men, where they could use the mind, ideate, and in this way, be happier in life. Ideas is what make humans more human.
