Language accelerates learning and creation by permitting communication and coordination... A new idea can be spread quickly if someone can explain it and communicate it to others before they have to discover it for themselves.
But the chief advantage of language is not communication but autogeneration. Lanauge is a trick that allows the mind to question itself; a magic mirror that reveals to the mind what the mind thinks; a handle that turns a mind into a tool. With a grp on the slippery, aimless activity of self-awareness and self-reference, language can harness a minto into a foundation of new ideas.
