Through language people can give advice. Others, through language, can share their perspective on a situation, which in hindsight may make that situation clearer to another person. Words can, and many times do, reveal truth. People's minds become so biased from the lies that they are told that many times only the testimony of a witness can convince them of the real truth. It is then, when people fail at this, that they begin to have problems because they are not using language to the best of their ability.
All languages are aesthetic.
Just think of how beautiful poetry is. Take the opportunity to listen to people speaking in a language other than your own. The words sound so beautiful and flow together so smoothly that one can't help but wonder what they mean. Words are colorful, when used correctly by an imaginative person. They can paint pictures and tell stories, write books, create poetry, share thoughts, feelings, secrets, and even tell jokes.
